In the past decade there has been increasing visibility of malaria control efforts at the national and international levels. The factors that have enhanced this scenario are the availability of proven interventions such as artemisinin-based combination therapy, the wide scale use of insecticide-treated nets (ITNs) and a renewed emphasis in indoor residual house-spraying. Concurrently, there has been a window of opportunity of financial commitments from organizations such as the Global Fund for HIV/AIDS, Tuberculosis and Malaria (GFATM), the President's Malaria Initiative and the World Bank Booster programme.
The case study uses the health policy analysis framework to analyse the implementation of a public-private partnership approach embarked upon by the government of Tanzania in malaria control – 'The Tanzania National Voucher Scheme'- and in this synthesis, emphasis is on the challenges faced by the scheme during the pre-implementation (2001 – 2004) and implementation phases (2004 – 2005). Qualitative research tools used include: document review, interview with key informants, stakeholder's analysis, force-field analysis, time line of events, policy characteristic analysis and focus group discussions. The study is also complemented by a cross-sectional survey, which was conducted at the Rufiji Health Demographic Surveillance Site, where a cohort of women of child-bearing age were followed up regarding access and use of ITNs.
The major challenges observed include: the re-introduction of taxes on mosquito nets and related products, procurement and tendering procedures in the implementation of the GFATM, and organizational arrangements and free delivery of mosquito nets through a Presidential initiative.
The lessons gleaned from this synthesis include: (a) the consistency of the stakeholders with a common vision, was an important strength in overcoming obstacles, (b) senior politicians often steered the policy agenda when the policy in question was a 'crisis event', the stakes and the visibility were high, (c) national stakeholders in policy making have an advantage in strengthening alliances with international organizations, where the latter can become extremely influential in solving bottlenecks as the need arises, and (d) conflict can be turned into an opportunity, for example the Presidential initiative has inadvertently provided Tanzania with important lessons in the organization of 'catch-up' campaigns.
Malaria remains one of the major tropical challenges in the world today. Based on World Health Reports 1999–2004, the number of malaria deaths globally has been estimated at 1.1–1.3 million . The most recent World Health report estimates that malaria incidence rates are 350–500 million per annum . In the past three decades, malaria has, however, encroached upon areas where it had formerly been eradicated or had successfully been controlled, offsetting the gains attained in the latter half of the past century . The disease is endemic in 107 countries with some 3.2 billion lives at risk of transmission. About 60% of the cases of malaria worldwide, 75% of global falciparum malaria cases and more than 80% of malaria deaths occur in Africa South of the Sahara. Plasmodium falciparum causes the vast majority of infections in this region and about 18% of deaths in children under five years of age .
Studies focusing on under-five children in African populations conclude that 600,000 children contract cerebral malaria yearly, with a case fatality rate of 20%. Severe malaria due to anaemia occurs in 1.5 – 6.0 million African children, with a case fatality rate of 15% . Malaria is also a major threat to pregnant women and adversely affects foetal growth and newborn survival through low birth weight.
The socio-economic impact of malaria is extremely high in endemic countries. It has been observed that over the past 25 years the economic growth in malarial countries has been hampered . It incapacitates the workforce, leading to decreased economic productivity and output in various sectors of the economy .
In the past decade, proven interventions, such as artemisinin-based combination therapy (ACT), the wide-scale use of insecticide-treated nets (ITNs) and a renewed emphasis in indoor residual house-spraying (IRS), are available for combating the disease. The challenge is to ensure that these relatively inexpensive interventions reach a major proportion of the population through universal coverage.
A number of global initiatives have been developed leading to increased awareness of malaria such as the Roll Back Malaria (RBM) initiative spearheaded by the World Health Organization's Director General in 1998, followed up by the Abuja Declaration on Roll Back Malaria by African Heads of State , and most recently a statement made by the World Health Assembly . In this statement, member states are urged to establish policies and operational plans to ensure that at least 80% of those at risk of or suffering from malaria benefit from major preventive and curative interventions in accordance with WHO technical recommendations, by 2010 so as to ensure a reduction in the burden of malaria of at least 50% by 2010 and by 75% by 2015.
The Abuja targets were revisited in 2006 where all the indicators were raised from 60% to 80% on the basis of current opportunities and increasing visibility of financial support from the global community such as the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM), President's Malaria Initiative (PMI), World Bank Booster funding and the Bill and Melinda Gates Foundation .
During the last 15 years, a large body of evidence has been compiled on the key technical and managerial aspects of ITNs as well as on their efficacy and effectiveness. A systematic review of 22 randomized controlled trials showed a consistently high impact of ITNs [10, 11] preventing malaria episodes. Current debates around ITNs, internationally and nationally where malaria is endemic, is the appropriate delivery mechanisms for wide-scale use of ITNs [12–15]. The advantages and challenges of the various delivery mechanisms have been discussed.
Tanzania has been on the forefront in the promotion of the use of ITNs from research projects in the 1980s and 1990s [16–18] and validation in larger field trials in early 2000 [19, 20] to a nation-wide programme through a discount voucher scheme delivered through a public-private partnership approach [21, 22]. The ITN activities in Tanzania were closely linked to international developments including: randomized controlled trials [23–25], technological developments in the home treatment kits , rationalization of taxes and tariffs and expansion, and investment in Long-Lasting Insecticide-treated Nets (LLIN).
Through the nationwide discount voucher scheme, pregnant women access the vouchers at the Antenatal clinics in public health facilities. The voucher is redeemed for a mosquito net of her choice at a shop in the catchment area of the health facility by adding a variable top-up, ranging between 0.75 – 1.25 USD depending on the size of the mosquito net purchased [21, 22].
Since April 2008, the pregnant woman voucher has been complemented with an infant voucher scheme, which uses the same delivery mechanism as the pregnant woman voucher through the Antenatal Clinics. It is also a country-wide initiative. Until mid-year 2008, the two schemes combined totaled a redemption of 3.5 million nets as a share of the mosquito nets available in the country through these groups .
A recent study carried out in a rural setting in Tanzania showed that a combination of interventions, such as vouchers for the vulnerable groups, free mosquito nets and full-cost nets in the local market have proved to raise the coverage of mosquito nets in different segments of the population substantially thus complementing each other . A lot of research on ITNs has concentrated on the outcomes and impact of the intervention on malaria and most recently investigations have been done on various delivery mechanisms to ensure the tool is available to the target groups as alluded to above. However, there is very little covered in the research in terms of health policy analysis in malaria  and Njau et al, in press). However health policy analysis has been used in HIV/AIDS and has also been used to describe health sector reforms in the country [30–33].
Community health financing (CHF) was introduced in Tanzania through the health sector reforms since 1995 [31, 34], with an overarching aim of resource generation and equity. Using the health policy analysis framework, the authors point to the top-down approach in the development of the community health financing policy, where there was no interaction of the central Ministry of Health (MoH) with the sub-national levels in the conceptualization of the CHF[30, 31]. Furthermore managerial weaknesses were also observed. These included lack of supervision and accountability by the district managers.
In Mwanza, Tanzania, the health policy analytical framework was used to describe extensively how HIV/AIDS research findings were successfully been translated to policy . The trial demonstrated the effectiveness of improved treatment services for Sexually Transmitted Infections in preventing HIV infections. The factors that influenced the policy impact of the research results included: 1) research data packaged in a simple manner digestible by politicians, 2) researchers and policy makers formed strategic alliances for the policy shift, and 3) the policy environment was conducive.
Data collection tools
Qualitative and quantitative methods were used in the study to highlight the challenges experienced at the different levels of the health care delivery system in the implementation of the country-wide subsidy scheme.
The qualitative methods included: key informant interviews from the national and district levels, policy characteristic analysis, stakeholders' analysis and focus group discussions.
Key informant interviews
The interviews were carried out through 2005 and 2006. A balanced selection of key informants were interviewed from the MoH, the National Malaria Control Programme (NMCP), the CHMT in Rufiji district, Reproductive and Child Health (RCH) coordinators in randomly selected health facilities in Rufiji, stakeholders sub-contracted by the MOH to implement the TNVS and stakeholders involved in malaria control through technical support to the MOH. Other groups interviewed included influential people from the community and the private sector. The private-for-profit sector included some of the Tanzania Net Manufacturing companies, Price Waterhouse Coopers, wholesalers and retailers while the private-not-for-profit included Population Services International (PSI) and the Christian Social Services Commission (CSSC). The synthesis identified 14 key informants from the onset to be interviewed, however, 10 more were added through a snowball effect, as key people mentioned through the first interviews were sought and added to the list .

Stakeholders' analysis was also used in the research and enabled the reviewer to understand the actors' behaviour, interests, intentions and interactions. It further allowed the assessment of the actors influence and resources that they brought to bear on decision making in the development and the implementation of a PPP initiative in the wide-scale use of ITNs . The information for each group/actor was arrayed according to the group interests, the level of resources the group or actor possessed and the groups' position on the PPP initiative. The resources that were identified in the stakeholders analysis were drawn from the preliminary policy characteristic analysis [37, 38]. These included (a) technical resources, described here as the inherent technical expertise that the stakeholder has that would be critical to the implementation of the policy or by virtue of the stakeholders position in relation to the implementation of the policy (for example, the presence of the Tanzania Net Manufacturers in the country providing a market for mosquito nets); (b) political resources, expounded here as the influence that the stakeholder has on the ITN subsidy scheme through direct or indirect interaction with government officials; and (c) financial resources, the stakeholders influence over the economic situation. For example, PSI conducting social marketing of ITNs in the remotest parts of the country, or the UK Department for International Development availing financial support towards social marketing initiatives.
The stakeholders' analysis enabled the synthesis to look retrospectively at the key actors and groups of actors and their influence, or lack of it, in the development and the implementation of a PPP in scaling-up ITNs country-wide. The outcome enabled the analyst to draw recommendations for future health policies in relation to optimizing participation under conditions of limited resources .
Force-field analysis and micro-political mapping were used in support of the stakeholders' analysis, where the former clarified the array of support on the discount voucher scheme by different stakeholders and micro-political mapping showed the sources of actors influence over the implementation of the ITN subsidy scheme in the decision making phase, the pre-implementation and implementation phases .
Focus group discussions
Two focus group discussions (FGDs) were conducted where purposive sampling was used to select individuals from two separate villages from Ikwiriri and Kibiti divisions under the Rufiji DSS. Each group, consisting of 8 – 12 individuals, included women of child-bearing age and some women in these groups were pregnant and others had infants at the time of the survey. Older women in the society of different socio-economic status were also included . Each FGD took between 45 – 50 minutes. Guiding questions were prepared with the major aim of finding out from the women what the major health problems in the village were, how they addressed them and whether they were acquainted to the discount voucher scheme.
Qualitative data analysis
Triangulation of the information accrued from the interviews was done through published and grey literature.
Policy characteristic analysis
A policy characteristic analysis was used to provide a systematic understanding of what the policy change was designed to do, the context in which the policy was implemented, the consequences of the change and the reactions of the public and/or the bureaucracy .
A number of informants came-up with quite similar issues and perspectives on key subjects related to the issue. One or two quotes representing the thoughts are quoted to reflect the thoughts of the key actors; however they are kept anonymous. Controversial issues and perceptions of some key actors were also quoted to enlighten the reader on the hurdles that the implementers faced and how they were able to overcome them. In most instances the quotations are validated through the literature review which was conducted. This approach is described as the grounded theory [42, 43].
A retrospective cohort of women of child bearing age from Ikwiriri and Kibiti divisions of the Rufiji district in the Coast Region – the Rufiji DSS database was followed-up twice in the survey coinciding with the normal DSS updates (Figure 1). The first follow-up was during the February 2005 – May 2005 cycle, immediately after the discount voucher was launched in the district. The second follow-up was in the June 2005 – September 2005 cycle, when the discount voucher scheme had been operational for eight months. The Rufiji DSS involves continuous surveillance of households and members within households in cycles or intervals of four months each. The information collected in these cycles includes demographic, household, socioeconomic and environmental characteristics of the population .
The sample size estimation for the number of households with the probability of having pregnant women was calculated using the estimates of the proportion of pregnant women and women of child bearing age in the RDSS census of 2003. The anticipated proportion of pregnant women with a mosquito net through the TNVS was estimated at 50%. With a precision of 5% and an average household of 4.7, a total of 1048 households were sampled. Systematic random sampling was used, where nine villages were selected from Kibiti, Mchukwi and Bungu wards of Kibiti division, and three villages from the Ikwiriri, Mgomba and Umwe wards (Figure 1).
A semi-structured questionnaire was used to collect information on ITN possession and use. This was triangulated with subsequent surveys carried out by the monitoring and evaluation contractors during the implementation of the TNVS . The questions included knowledge of TNVS, access to ITNs, barriers to access and redemption mechanisms. The relationship between socio-economic status and health has been an area of increasing interest in recent years [46, 47]. A number of studies have used the socio-economic status to predict variance against mortality of children under five (infant and <5 mortality) and health interventions such as household possession of mosquito nets [44, 48, 49]. Each member of the cohort of women of child-bearing age was matched with the respective socio-economic household indicator index derived from the Rufiji DSS in 2000 for mosquito net possession. The socio-economic data was collected during the October 2000 – January 2001 Rufiji DSS cycle. This included asset ownership, housing conditions, source of energy for cooking, type of water and sanitation . Principle Component Analysis, using Stata 7.0 (Stata Corporation), was applied to the socio-economic data to obtain a proxy index for household socio-economic status [44, 50]. The cohort was divided into socio-economic quintiles for analyses .
Data management for the quantitative analysis
Data was entered into Excel® and processed in Stata Version 9.0®. Data was entered twice and cleaned by data managers at the Rufiji DSS. The analysis was done for computing frequencies, Chi square tests and calculating Confidence intervals for examining the real differences in net use amongst the cohort of women of child-bearing age followed up and the difference in net acquisition of the different social economic groups.
Challenges in the implementation of the country wide subsidy scheme through a PPP approach
The first part of this synthesis analysed the period of 'building momentum' toward a country-wide scale-up of a discount voucher scheme. The main conclusion was that the PPP approach to the initiative was made through incremental approaches both at the national and international levels and the process was dynamic and complex and far from linear. Secondly, the analysis also observed that the policy implementation has stretched over several years and is still evolving.
Tanzania is a fairly stable country politically with a unitary system of government embedded in its socialist history . Since 1995, the government has turned to a market-based economy and has in the recent past introduced a series of comprehensive frameworks to address the issues surrounding poverty, with Vision 2025 as the overarching development framework . In this relatively stable context and a maturing open market, the voucher scheme for the control of malaria was not implemented without challenges and 'hiccups.'
Marketing challenges in promoting ITNs – White Sands meeting 1998
As the agenda had been set, with a firm foundation for the PPP approach in scaling up ITNs, a number of challenges were to be addressed in the pre-implementation stage. One of the milestones in the momentum that was being created in providing a conducive environment for the up-scaling of ITNs was a meeting held at the White Sands Hotel in 1998 . A serious barrier to ITN promotion identified at this meeting was taxation. The meeting outlined plans of action for follow-up and assigned various tasks to the different stakeholders. Some of the tasks included outlining a strategy to petition against the introduction of Value Added Tax (VAT) on mosquito nets and insecticides, lobbying members of parliament and influential individuals. Wide dissemination of the meeting recommendations to key stakeholders such as the World Bank (both nationally and internationally), WHO, the World Trade Organization and the media. Finally, in the MOF Bill of 1999/2000, the tireless efforts of all stakeholders proved fruitful when mosquito nets were zero rated for import duty and VAT, and classified under the essential drug list of the MoH. The 20% VAT levied on 100% polyester yarn was refundable to the manufacturing companies as rebate on production of relevant documents, which had been audited and certified by the Tanzania Revenue Authority. In this manner, they established the volume of imported yarn, which was actually used to produce a certain number of mosquito nets (as polyester yarn could also be used to make other fabrics) .
A revisit of the rationalization of taxes and tariffs on ITNs
An issue already well dealt with during the decision making stage, appeared once again in the pre-implementation phase (phase II): the issue of taxes and tariffs related to ITNs, with the re-introduction of VAT by the Ministry of Finance (MoF) in May 2002 on raw materials for production of mosquito nets. This was discussed at length at the steering committee of the National ITN Strategy (NATNET) in 2003. One of the members of the committee remarked as follows;
"Lobbying is needed to re-instate zero rating on VAT as well as zero rating customs duty. There is a risk if this is not achieved in this budget (as the fiscal year for the Government begins June/July – hence any amendment had to be done before that) there will never be a revision. The Minister of Health has been made aware of this issue and information has been sent to the Ministry of Finance. The current tax policy favours imported nets as finished products imported are not subject to VAT. It was noted however that imported nets were not bundled and due to the uneven playing field of the imported nets versus locally produced nets there was a general supply shortfall of mosquito nets in the country (Steering committee member, 7 th March 2003)."
At the time of this synthesis the members of the NATNET steering committee were the Chief Medical Officer (the chairperson), the Programme Manager of the NMCP (the secretariat), the ITN Cell Team Leader, the UK Department for International Development, the Swiss Development Corporation, the President's Malaria Initiative, the Irish AID, WHO, UNICEF and PSI.
A tax reform task force is set-up
The NATNETs steering committee set-up a 'Tax reform task force,' with the objective of (a) providing an assessment of the changes at that particular time in the VAT legislation on the importation and local manufacture of mosquito nets, and (b) to make recommendations as to how to minimize the effect of the changes such that the tax burden was removed from the local manufacturer of mosquito nets.
On completion of its assignment, the task force observed that the amendments to the new taxes effectively restored the position of the old VAT Act of July 1998, where the mosquito nets produced locally and all the raw materials and overheads were VAT exempt. They were not able to claim back any VAT to the extent that they relate to domestic sales. In this case they would have to absorb this irrecoverable VAT by accepting reduced margins or passing it over to the consumer, through an increase in their selling price with the risk of reducing sales. However, importers of nets were zero rated for VAT at the point of entry. Thus, an uneven playing field between the locally-produced nets and the imported nets was created. The task force looked at the rationale behind the 2002 changes and summarized their recommendations as follows: the pressure for change in relief afforded in any country could be because of special interest groups who felt that the special relieves are disadvantaged to them or does not cater for their particular needs. Secondly, there may be pressure from within the government administration to change the reliefs available by increasing or decreasing them to remove inequalities of treatment, to remove ambiguities, to raise revenue or to give relief for social reasons.
The task force visited two of the three net manufacturing companies in the country at the time. The companies stated there would be an increase of 10 to 20% in mosquito net price should the government re-introduce VAT. The course of action suggested by the task force was that, a written submission had to be prepared by the MoH, from the senior health officials to the MoF, making a case for the changes required and proposals for the re-wording of the schedule. Subsequent to this submission, meetings were to be held between senior MOH officials and the Commissioner of Finance. The task force advised the MoH to request for the following in their submission to the MoF : (a) to leave mosquito nets as VAT exempt, which implies no VAT at point of sale to consumer but VAT charged and not recoverable on all manufacturing inputs; (b) to levy a customs duty of 10% on ready-made mosquito nets. Therefore, leveling the playing field between imported nets and domestic mosquito nets.
Discourse between technical advisor and the TNVS steering committee
The NATNET steering committee did not agree with the recommendations of the task force and, therefore, wrote a memo to the Permanent Secretary of MoH , through the UK Department for International Development (as a member of the steering committee), requesting the restoration of zero rating on the sale of nets by domestic manufacturers and the removal of customs duty on material imported for the manufacture of mosquito nets. The memorandum also stressed that what the appointed task force had recommended on the tax issue was contrary to the international commendation made to Tanzania in early 2000 on the progressive rationalization of taxes and tariffs on mosquito nets and inputs in the production of mosquito nets and was a standing example to other malaria endemic countries.
To re-enforce the steering committees plea, the net manufacturers had written a memorandum to the Commissioner of VAT, dated 2nd August 2002, requesting the Tanzania Revenue Authority to re-visit the new taxes imposed on domestic mosquito nets. The memorandum was copied to the Permanent Secretaries of the MoH, the MoF and the Ministry of Trade and Industry, the Programme Manager of the NMCP, WHO, the Tanzania Essential Health Intervention Project (TEHIP) and PSI.
Government medical stores department affected by tax reforms
Furthermore, the Medical Stores Department (MSD), which was the sole government semi-autonomous organization responsible for ordering pharmaceuticals, medical equipment and supplies on behalf of the government, found that the new tax amendment also affected them. They stated in their memorandum  which they addressed to the Permanent Secretary, MoH, "......as a result 10% import duty is levied on all pharmaceuticals, including vaccines, TB and Leprosy drugs procured by her departments, and those given as donations. This has a very negative impact over our budget and ultimately to the end user, which is the Government health facilities. MSD has applied for a waiver of such taxes through the Permanent Secretary, Ministry of Finance (vide memorandum MSD/003/215/2002 dated 24 th July 2002) and while waiting for an official response, more consignments are arriving at the sea and airports, demanding huge payment arising from taxes, port storage and demurrage."
The MSD ended their memorandum by requesting the Permanent Secretary, MoH to discuss this issue bilaterally with the Permanent Secretary, MoF, as a matter of urgency. In a subsequent meeting of the NATNET steering committee on 25th June 2003, it was observed that, as a result of pressure by the NMCP through the ITN Cell and other stakeholders (including private and public), the MoF endorsed in the 2004 Budget that VAT on mosquito nets was zero-rated and the customs duty on the yarn was also removed. This was a remarkable breakthrough in ensuring that the price of nets remained stable in the country.
The scenario depicted here reinforces the high administrative and technical resources which the individuals in the steering committee brought to bear in this particular high stake issue and its consequences in the public arena. The malaria agenda turned from 'business-as-usual' to a 'crisis' event. Without these concerted efforts the government would not have resolved the tax rationalization in a timely manner, which would have been detrimental to the PPP approach to scaling up ITNs in the country.
The members of the steering committee were consistently supporting the ITN subsidy scheme with high influence over the events that occurred in both the decision making stage and the pre- implementation phase (Figures 5 and 6) and high support in the decision making process (Figure 2).
Challenges faced in signing the GFATM award
As the opinion leaders were being groomed such that there was heightened political commitment towards malaria control in the country; behind the scenes there were a number of teething problems in the pre-implementation phase with regards to the signing of the GFATM award.
The United Republic of Tanzania (URT), through its MoH, had been awarded USD 19 million from the GFATM for the implementation of the TNVS . There were a number of critical and fundamental organizational arrangements, which the MoH and other government sectors had to lay down from the period that the GFATM grant agreement had been signed in 2002 to the launching of the Tanzania National Voucher Scheme in October 2004. It was also observed that in parallel, the GFATM, in these very early years of their operations, was also developing and strengthening its own systems as they delivered financial support to recipient countries with variable monetary and administrative mechanisms.
This scenario may have prompted one of the stakeholders spearheading the TNVS within the ITN cell to remark as follows:
"...GFATM have not always committed themselves to the development process. They call themselves development agencies, they do not want to hear about the context in which their money is being spent...they had no understanding or compassion that there are health systems constraints that one cannot solve within a 5 year programme (16 th January 2006)."
Most stakeholders interviewed in this synthesis noted that it would be prudent for GFATM grants in the future to allow a preparatory period within the proposal before the actual start date for implementation. Hence, the preparatory period would include all administrative issues and any other unforeseen logistical issues, which the recipient country would put in place prior to the implementation of the grant.
Bottleneck one: procurement, tendering procedures and structures for implementation
The TNVS was one of the first proposals to be accepted worldwide by GFATM in the first round for the call of proposals in 2002. In accordance to one stakeholder, "...one of the first ones around the world and one of the best ones too...(29 th October 2006)." But in spite of this, taking off and becoming active was another issue.
In the Tanzanian context, the TNVS grant took one year from 2002–2003 for tendering of contractors who would be involved in the actual implementation of the programme. These included the Mennonite Economic Development Agency, the World Vision International, the Ifakara Health Research and Development Centre and the London School of Hygiene and Tropical Medicine (LSHTM). The time was also spent in appointing a team leader for the programme. In 2003, the team leader was recruited at the beginning of the year and an administrator and a communication officer were recruited at the end of 2003. The recruitment of the technical staff for the ITN cell was subjected to the normal procurement procedures of the MoH through competitive bidding. The process involved, preparations of the expression of interest through advertising of the posts, calling for the proposals, evaluation, awarding and negotiations. Financial support for the technical staff of the ITN cell was made available from the Swiss Development Corporation.
Bottleneck two: principles of handling government foreign currency
The other bottleneck that was faced by the MoH, after being awarded the TNVS agreement, included principles of handling foreign currency by the government as stipulated by the MoF. The MoF referred to an Act of the government, which states that foreign money from donors availing financial support to the United Republic of Tanzania through the public sector should be channelled through the MoF before being handled by the recipient ministry concerned. The MoF was the sole custodian of that fund and would be the one signing the grants on behalf of the Government of Tanzania rather than the implementing ministry. This was in spite of the fact that in the TNVS grant proposal, the Principle Recipient (PR) was the MoH. In this respect, the PR had been selected by the Country Coordinating Mechanism in the country to be legally responsible for programme results and financial accountability, as stipulated in the GFATM fiduciary arrangements at the time . These organizational issues between the two ministries delayed the signing of the agreement by two weeks from the day it was awarded. A related financial bottleneck was the issue of the sub-contractors identified to implement the TNVS being required by government procedures to pay VAT. However, the GFATM had set a condition in their guidelines for the application for grants at the time, that the grants that they would award were not to be used by the recipient country to pay VAT. One of the stakeholders, who had been selected independently as the 'Local Fund Agent' of the GFATM grants in the country was Price Waterhouse Coopers. As the Local Fund Agent, they monitored the implementation of the activities of the GFATM, including the contracting negotiations and agreeing on the provisos and verifying the plans at the initial stages . Price Waterhouse Coopers worked tirelessly with the MoF to get a government notice to be signed by the MoF, which was subsequently placed in the government gazette, to relieve the recipients of the GFATM award on the payment of VAT.
The Local Fund Agent is only a medium supporter to the ITN subsidy scheme in the key steps towards the implementation of the scheme, as he confronts the complexities of the procurement hurdles of the Central Tender Board and MoF bottlenecks (Figure 2). His influence over the scheme however shifts to 'medium/high' as he puts all his efforts to ensure that there are solutions to overcome the problems (Figure 6).
Adding the bottlenecks mentioned above equalled to a whole year's delay in the implementation of the TNVS programme. In fact, one of the respondents was quoted as follows, "The GFATM was close to scrapping the programme. It took a very senior official from the GFATM to come to Tanzania and institute negotiations so that the programme was given a new life. Basically by saying that the start date is different from the actual start date that was originally in the contract ... (29th October 2006).' Furthermore another interviewee, who was an International Public Health specialist advising the MoH on health issues, commented, "...by coincidence I was in Tanzania when the Portfolio Manager was in Tanzania definitely with instructions to stop the project because of an 11 months delay in issuing contracts. They felt that this was due to technical incompetence (18 th October 2006)."
The GFATM at the international level hailed Tanzania for being one of the first countries to be awarded a GFATM grant and were confident that they would not be disappointed in the implementation of the intervention. However, within nine months of the release of the funds to the MoH, and no implementation having taken place, they quickly reverted to being 'opposed,' to the intervention short of scrapping the grant as observed in Figure 2.
Joint efforts open a window of opportunity in salvaging the GFATM grant
A joint memo was written by the Chair, Roll Back Malaria 'Working Group on scaling up ITNs' and the RBM Secretariat Focal Person, East African Regional Network to the GFATM, in August 2004 requesting for a 'No-cost Extension of Phase I: Jan 2005 – 31st October 2005 '. This memo was copied to the Permanent Secretary of the MoH, the Executive Secretary of RBM Secretariat and WHO.
In part the request is quoted as follows "...Despite the delays, much has been accomplished that is essential to a rapid and efficient roll out of the programme. In the 18 months since January 2003, there have been dramatic increases in domestic commercial market distribution and sales of both bundled and treatment kits (2.3 million ITNs) and separate Insecticide Re-treatment Kits (2.6 million kits) for existing nets even without the voucher due to strong demand creation supported by the NATNETs programme and the low cost of nets on the domestic market. The voucher will now come at the best time to add greater rural penetration and equity of access to the rapidly growing culture of ITNs...The preparatory stage also included a pilot voucher distribution in two districts to be completed and lessons incorporated into the first design of roll out.... Counterfeit resistant vouchers have been designed, produced and procured...detailed work plans for a staggered nation wide launch schedule have been developed... ."
The memorandum also stressed that there was no blue print elsewhere for a country-wide discount voucher scheme, earmarked for the control of malaria. Secondly, it used a novel approach of bringing together and building two existing systems: the public sector arm, where the pregnant women were receiving the discount vouchers, and the private sector distribution of the commodity, in a new configuration in order to achieve high coverage, efficiency, equity and sustainability of ITN use by the most vulnerable group.
One interviewee remarked as follows in relation to the uniqueness of the scheme, "This is not only the first voucher project done in Tanzania. It is the first nation-wide voucher programme addressing health that has ever been done in Africa (2 nd February 2006)."
The memorandum also noted that changes in public systems and strengthening take both time and careful preparation to get right. However once accomplished provide a solid foundation for rapid and sustained progress .
The GFATM endorsed this request and subsequently the NATNET project lost almost 2.5 million USD due to the delay.
In relation to the reaction of the GFATM to the delays that Tanzania experienced, one stakeholder had the following point of view...."the GFATM as a funding agent, for them it was expedient to fund projects that bought nets hence less logistics as all the money would be spent in the first week. As opposed to a systems approach which was intended to spend money continuously over time....they would prefer campaign type of approaches rather than system strengthening approaches (18 th October 2006)."
Joint efforts between national and international stakeholders opened a window of opportunity in salvaging the GFATM award for the implementation of the TNVS.
Contractors of the Tanzania National Voucher scheme and the challenges they faced
The three major contractors in the implementation of the TNVS had their own experience and challenges as they were learning-by-doing in this massive scale-up exercise of ITNs in the country. In order to have a sense of how the early days of implementation faired and their own experiences they were included in the stakeholders analysis.
The logistic contractor was MEDA, responsible for all the logistic arrangements for the production of vouchers, identifying the retailers and wholesalers and reimbursement of the manufacturers of the mosquito nets. The Director of MEDA at the time described their responsibilities as the logistic contractor in the following manner "....designing and printing of vouchers, ensuring vouchers get to the District Medical Officer and then to the Reproductive and Child Health clinics, identifying and signing up the retailers and wholesalers and the net manufacturers through out the country....We are involved in every step of the movement of the voucher including the final step which is the payment to the wholesalers and the manufacturers (2 nd February 2006)."
Regional managers from MEDA were placed in each region. They approached the district on the implementation of the TNVS through the District Medical Officer (DMO). World Vision International and Care International were appointed as the training and promotion contractors. Their responsibilities included designing promotional materials for TNVS. Apart from training the Council Health Management Teams and the RCH staff, they also included the District Planning Officer, the District Executive Director and the District Cultural Officer of the respective district. Ifakara Health and Research Development Centre and the LSHTM were the monitoring and evaluation contractors for TNVS. The institutions were independent in their monitoring with a schedule that included different types of surveys. These were household and health facility surveys, qualitative studies through in-depth interviews, tracking of vouchers and retail auditing. The baseline for the household survey was carried out in July-August 2005 and it has been repeated yearly thereafter .
The Director of MEDA expressed the fears that he had prior to the implementation of the TNVS programme, especially bearing in mind there was no blue print to follow. He was quoted as follows '....fear of the voucher being produced as forgery, how the clinic staff would react to additional responsibility, how would the retailers and wholesalers perceive vouchers?.........some of the wholesalers said that if it is the government we do not want to be involved. An NGO we can be involved (2 nd February 2006).'
When probed as to why the private sector was weary of working with the government, the Director explained "....There is a lot of suspicion in the private sector about the government and actually vice versa because one of the things that you struggle with is that many people in the government and Non-Governmental Organizations see business as evil. It is very difficult to see them as potential partners......... The reality is this project does not work without the public sector support at all or the private sector support at all and really the private sector has reacted even better than we thought they would. You have manufacturing companies which have purchased 5 or 6 trucks, because the distribution is so much more developed (2 nd February 2006)."
Another challenge observed was the underestimation of the vastness and geographical complexity of Tanzania. The topography in some districts really challenged them where districts had health facilities built in complex infrastructure. The Manager of the Logistics Component in MEDA also mentioned the problem of existing revolving fund projects within some of the health facilities in the country. The MOH had taken action on this issue by writing a memorandum to all DMO's informing them that given the nature of the voucher scheme, it was deemed essential that existing ITN activities do not contradict or hinder the principle of PPPs, which the TNVS was embarking upon. The regions were requested to examine ways in which existing ITN activities (such as revolving funds, sale of nets by health facilities, and free distribution of ITNs) could be phased out once the TNVS was introduced in the respective districts. Furthermore the districts could explore means of integrating the discount voucher scheme so as not to create two parallel systems, which would be difficult to implement.
The training and promotion contractor alluded to the timelines for the implementation of the TNVS. He noted that the period of covering the whole country with the scheme was too short. He took into cognizance the year that was spent on administrative and logistic issues, after the signing of the grant in 2002 up to the actual launch in 2004 as already mentioned. The contractor felt that the work was very intensive. It was also noted by this contractor that some retailers, which had been selected in respective districts to sell ITNs to the pregnant women, had a tendency to inflate the prices of the mosquito nets. Hence, this became a barrier to the pregnant woman accessing the mosquito net against the intended policy of the intervention.
The monitoring and evaluation contractor noted several challenges in two surveys, which had been conducted at the time of this synthesis. In a qualitative study conducted in 2006 in four districts by the monitoring and evaluation contractor, the nurses expressed that there was work overload since the setting in of the voucher scheme. It was also apparent that there was a period where the districts experienced voucher stock outs, which were related to administrative arrangements of replenishment by the CHMTs. As noted by the other contractors, the RCH staff sometimes became a barrier to women as they demanded a proof of 'top-up.' Another problem observed was that the vouchers were not reaching the remotest part of the districts, as they were not carried by health workers who went to outreach and mobile services within respective districts. The contractor also noted that some of the women interviewed were not aware of the 'face-value' of the voucher. They equated the voucher entitling them to a cheap net and did not perceive that they had to pay a 'top-up.' The coordinator of the monitoring and evaluation component of TNVS expressed that the experience the IHRDC had on social marketing of ITNs in Kilombero-Ulanga project in 2000–2002 was very useful in the large scale country wide discount voucher scheme .
The subsidy scheme is challenged with a directive from the Head of State
Another challenge that faced the subsidy scheme was a directive from the head of state of the URT related to free delivery of mosquito nets in the country. The World Economic Forum, a not-for-profit organization which holds annual meetings on various topics, held its summit in Davos, Switzerland with the theme 'Taking Responsibility for Tough Choices '. One of the agendas put forward at the meeting was debt relief for Africa. Professor Jeffrey Sachs, Director of the Earth Institute at the University of Columbia and Director of the United Nation Millennium Project, mentioned at the meeting that debt relief was the only hope for economic development in Africa. He called for the cancellation of multilateral debt to the most impoverished nations in Africa.
The honourable President of the United Republic of Tanzania, Benjamin William Mkapa was at the time one of the Commissioners of the Commission of Africa at the WEF. In response to Dr Sachs remarks, he made the following statement, " Each year I must find several million dollars to service the Tanzanian debt. I can use that money for bed nets, which would prevent the loss of 1 million lives every year to malaria."
In response to the honourable President's plea, a famous actress – Sharon Stone – pledged USD 10,000 to buy bed nets for Africa. She wanted to raise 1 million USD, which would go directly to the GFATM to buy mosquito nets to stop deaths from malaria in the developing world .
In March 2005, the Tanzania National Coordinating Mechanism  of the GFTAM met to negotiate on the best use of the 'Sharon Stone' funds (Alex Mwita, personal communication). After a lot of debate and in spite of the MoH's position in relation to the delivery of mosquito nets through PPPs, it was agreed that LLINs would be bought and delivered free-of-charge with the measles, Vitamin A and de-worming campaign, which was to take place country-wide in July 2005. The target regions were Lindi and Mtwara as they had the highest infant mortality (129 and 126 per 1,000 live births, respectively in Lindi and Mtwara) and the highest under five mortality in the country (217 and 212 per 1,000 lives birth, respectively in Lindi and Mtwara), compared to a national average 99 per 1,000 live births for infant mortality and an under five mortality of 112 per 1,000 live births .
However, by May 2005 only 20% of the pledge from the World Economic Forum had come through to Tanzania. The MoH had ordered LLINs in advance through the A-to-Z Textile factory, but had to cancel. UNICEF intervened to save the situation by agreeing to bridge the gap. UNICEF readily accepted to take this position as part of their cooperate agenda in protecting vulnerable groups in malaria-endemic areas in Africa through accelerated deployment of ITNs .
Conventional nets bundled with insecticide re-treatment kits were ordered from the same textile company and distributed to Lindi in July/August 2005 and Mtwara in December 2005 in the country-wide immunization campaign. A MoH official responded as follows about the free net distribution campaign "The private sector thought that we are killing the net market in those regions, we are working against the public-private partnerships. But we allayed their fears in that this was a one-off activity not continuous. An offer, a Presidential initiative which we could not go against, the market for nets is not limited to under fives only. The population of under-fives is 20%. 80% of the people still need the nets (3 rd February 2006)". One of the net manufacturers went as far as writing a memorandum to the Roll Back Malaria Secretariat in Geneva related to the intention of the country intending to distribute ITNs freely to vulnerable groups against the standing agreement that Tanzania had in delivering ITNs through a PPP mechanism (memorandum dated 15th June 2005). In response, the RBM Director stressed that the government had through consultations embarked on the campaign as a one-off presidential campaign consequent to the precedents set at the Davos meeting in January 2005. Secondly, that the campaign had not changed the policy of the MoH with regards to the PPP approach in delivering ITNs. Thirdly, she stressed that the Demographic and Health Survey (DHS) results (2004/2005) were evidence that the country had increased ITN coverage in both vulnerable groups compared to the 2000–2001 data. Finally, she alluded to some of the indicators which were being observed from the launched discount voucher scheme, including high redemption rates by pregnant women up to 85% at the time, early attendance of pregnant women to antenatal clinics and an expanding domestic commercial market of bundled mosquito nets through strong demand creation pump-primed by social marketing. An administrator from the ITN cell had the following to say in relation to free ITN distribution "It was a fact that this letter the private sector wrote went to the Presidential level. The minister had to call us and the Programme manager, myself and the Permanent Secretary. We had to narrate how we reached this consensus, showing all the correspondence....... (24 th January 2006)."
In a meeting held by the NMCP to discuss the possibility of developing an equity voucher to address the 15% of pregnant women who were not redeeming their vouchers for a net, the MoH decided to clarify the issues surrounding free net delivery of mosquito nets in two regions in the country in 2005. The programme manager for malaria read a statement of the Ministry of Health and Social Welfare with regard to ITNs on behalf of the Director of Preventive Services in the MoH . "In summary, the MoH reiterated that the free net distribution in Lindi and Mtwara was an exceptional activity arising from the peculiar circumstances and in no way represented a policy shift within government. The statement also stressed that equitable protection of the most physiologically vulnerable groups will be encouraged through the consideration and development of targeted subsidies designed to encourage commercial sector participation in ITN distribution. Subsidies will be linked to utilization of other essential health intervention packages, such as antenatal and Expanded Programme for Immunization (EPI) services ."
Challenges of the TNVS at the community level
A retrospective cohort of women of child-bearing age from Ikwiriri and Kibiti divisions of the Rufiji district, Coast region, under the Rufiji DSS database were followed up twice in the survey coinciding with the normal demographic surveillance updates. The survey enabled the analyst to collect information on the knowledge of the women on the TNVS, access to ITNs, barriers to access and redemption mechanisms. The manner in which the women solved the challenges they faced in acquiring mosquito nets was also documented.
The cohort of women of child-bearing was matched with the socio-economic status of the households from the Rufiji DSS in 2000. From the 1,048 women who were being followed up, 698 matched in the first survey (February to May 2005) and 678 women matched in the second survey (June to September 2005). It was observed that the number of women in the two surveys did not match due to the specific questions that the survey was asking, including the acquisition of vouchers from the Antenatal Clinic by pregnant women for purchasing a mosquito net, and the observation that there could have been some migration of households from the study site within the five years difference between the two surveys.

Results of focus group discussions
Two Focus Group Discussions (FGDs) were conducted during the course of the survey. The first one was carried out in Ikwiriri Division at Tanga-mbili sub-village (Figure 1). This included 10 women of child-bearing age: with an age range of 18 to 30 years and an average of 25.4 years. Fifty percent of these women were pregnant at the time of the survey and the remaining had infants. The second FGD was carried out in Kibiti Division at Kibiti Central sub-village (Figure 1). Twelve women of child-bearing age were involved, with an age range of 17 to 45 years and an average of 27 years.
Sixty-eight percent of the women had received no formal education. Five percent had dropped out of school before completing their formal primary education. Only 28% had completed their primary education. Sixty-four percent of the women were small-scale farmers in rice paddies, 27% were housewives, and 9% engaged in small business such as selling fish and tailoring.
Malaria was identified as the major public health problem followed by diarrhoeal diseases and lastly HIV/AIDS, by a majority of the women. All the women affirmed that mosquito nets were readily available from the shops, shifting markets and vendors. They quoted that the price range depended on the size of the net: 3,500 Tshs – 4,000Tshs (about 3.5 – 4.00 USD at the time of the survey). They affirmed that the nets were bundled with an insecticide re-treatment kit. On the question of knowledge of the discount voucher scheme, one or two members of the groups described the scheme and others confirmed. Only two women in both FGDs were able to give the correct value of the voucher. The responses ranged from 350 Tshs – 2,250 Tshs. It was evident, due to the low literacy level of the women, that they did not actually comprehend what the face value of the voucher was. On the other hand it also reflects the level of sensitization that they had received from the RCH Coordinators when they attended their antenatal clinic and were first introduced to the scheme.
In addition to receiving vouchers from the public health facilities and the mission hospital, four mothers mentioned that they had received free mosquito nets from one of the mission health centres. However, 50% of the women said that they had received free mosquito nets during the measles campaign held in July 2005. In this campaign, all children under five received free nets and all of them were bundled with insecticide re-treatment kits. With regards to the problems surrounding the operationalization of the voucher scheme at the household level, two issues were described by the FGDs. One respondent mentioned that the RCH coordinators themselves were not conversant enough with the system hence they caused some one to leave the ANC without receiving a voucher. Even when some pregnant women deliver in the same clinic that they have been attending antenatal check-ups, they still did not get their voucher. Another woman actually confirmed that she had attended antenatal clinic at least twice in her pregnancy and up until the time she had delivered, she was never given a voucher. The second problem cited was the hiking of prices of mosquito nets by some of the shop-keepers since the discount voucher scheme began. Thus, the shop-keepers were actually benefiting from the discount voucher by over-pricing the mosquito nets compared to the price before the scheme began.
Interviews were also conducted with RCH Coordinators from three health centres and one hospital, which were randomly selected within the Rufiji DSS. The health facilities were the Ikwiriri Mission, (a dispensary), the Kibiti Health Centre (a public facility), Mariamu Consolota dispensary (a mission dispensary) and Mchukwi Hospital (a missionary hospital) (Figure 1).
The interviewees confirmed that the voucher scheme begun on the 14th February 2005 in two facilities and on the 15th February 2005 in the others. They received training for one day on issues related to malaria and the discount voucher scheme. The trainees were from World Vision International and the District Nursing Officer (she is the Integrated Management and Childhood Illness (IMCI)/Malaria focal point in the district). The RCH coordinators pointed to three major problems which they had observed since the scheme begun: 1) voucher books could be depleted before they were replenished by the district, 2) there were women who could not afford the top up to the voucher and, hence, did not redeem the voucher for a mosquito net, and 3) there were women who actually move into the paddy farms during the farming season and slept in fragile houses and usually these families were extremely poor. There was a very small probability of these women accessing the voucher let alone redeeming it.
Analytical features of the challenges faced in the implementation of the TNVS
The Abuja declaration clearly stipulated that countries endemic for malaria were obliged to ensure that there was a reduction of taxes and tariffs for all mosquito net products so that they became affordable to the communities . To meet this challenge, early in 1998, the MoH held a meeting with other relevant government sectors, multilaterals, bilaterals, the private sector for – profit and non-profit to set-up strategies to tackle the issue of taxes and tariffs on mosquito net products in Tanzania. The strategies included lobbying members of parliament and influential individuals, wide dissemination of the outcome of the meeting to international organizations and the media. The results were fruitful and taxes and tariffs on mosquito net products including insecticides used to treat the nets were reduced. His Excellency Benjamin William Mkapa at a fund raising dinner held in 2000, toward the 'Comprehensive malaria control project in Zanzibar' had this to say on the issue of taxes "...Tanzania was the first country to take action on the so-called "malaria taxes" last year, by reducing the total taxes on mosquito nets and insecticides to fight malaria to a combined rate of 5% only. This has made mosquito nets affordable to the people... ". Many countries at the time had not rationalized their taxes and tariffs on mosquito net products. To date only 15 of the 39 Abuja signatories of the malaria declaration in 2000 have reduced taxes and tariffs on this life-saving intervention .
The MoH was strategic in their approach to the tax rationalization agenda in (1) allowing a broad discussion around the tax reform required through a multisectoral meeting, (2) lobbying key national individuals and organizations, (3) strengthening alliances with relevant international organizations such as the World Trade Organization, WHO and the World Bank, and (4) making use of the media to bring the issue to the forefront in the eyes of the public. Most importantly the process was owned and led by the government itself. Ironically, the situation lasted only for two years: while the MoH was struggling to ensure how best the mosquito nets could now be delivered to the communities, the MoF re-introduced taxes and tariffs on mosquito net products in the country. The reason behind this is the generation of internal revenue through raising the tax base of some commodities . The synthesis could not explicitly identify whether the government officials from the MoF which were involved in the re-introduction of the taxes were different from those that reduced the taxes in 1999/2000; what is evident is that an overarching agenda of raising the domestic revenue of the country is overshadowing the efforts of the MoH in the control of malaria. All civil servants are governed in terms of their loyalties, values and expertise and avidly follow through their agenda in many instances. The MOF officials in this context have disregarded the history of the removal of taxes on mosquito net products in the first place having had no consultations with other relevant sectors on the subject, where they would have gleaned the repercussion of their decision on health .
Evidently, the rationalization of taxes and tariffs by the MOH under the particular clause that affected the mosquito nets also had an effect on the MSD, who independently struggled with the new tax bill. Subsequently, lobbying was carried out by the NMCP and key stakeholders and, in 2004, within the new fiscal budget of the government taxes and tariffs on mosquito net nets and related products were reduced again. The MoH, through its steering committee for NATNETS, was able to create an appropriate space to manoeuvre, in a complex policy issue and engaged other actors on the scene in a timely manner to further the malaria control agenda.
Tanzania was one of the first countries to receive a GFATM award for malaria control. Nonetheless, it took the country almost one year from the signing of the grant to the implementation of the discount voucher activities. The hurdles faced by the MoH during this period was partly due to the procurement bottlenecks within the Central Tender Board, but was also related to the organizational arrangements of the GFATM at the time: (1) the GFATM was a newly-formed funding organization for the three diseases. It was challenged with an urgent need to show results in the recipient countries and balance this with the latter managing the new financing mechanism , (2) at the international level it had high staff turnover with different portfolio managers assigned to countries within less than a year hence reducing the institutional capacity of these managers to follow-up on the design and scope of the proposals, (3) GFATM needed to be sensitive to the contextual and systemic issues surrounding recipient countries in as much as they demanded performance based management , and (4) the organization had to make provision for recipient countries to build health systems through the grants they disbursed which are critical for successful programmatic implementation. These include strengthening the human resource capacity, contracting and procurement procedures, concrete monitoring and evaluation plans etc. One of the major challenges alluded to by the WHO in reaching the Millennium Development Goals is failing or inadequate health systems. Without building and strengthening these systems it will be difficult to reach communities with the desired health outcomes on time, reliably and in sufficient quantities . It is encouraging that the GFATM has since 2005 incorporated health systems strengthening issues within country proposals .
The international community through the RBM working group on scaling up ITNs made a historical and timely intervention to salvage the discount voucher programme when it was threatened to be 'scrapped' by the Board of the GFATM in 2004. Their sensitivity to the public health systems in the country enabled them to articulate the nature of the unique approach that Tanzania had embarked upon in the delivery of ITNs through a PPP to the GFATM and request for a no-cost extension so that the programme could continue.
In 2005, a year into the implementation of the TNVS and at a time when the NMCP had covered 75% of the country with the scheme; a presidential initiative brought uncertainty to the status quo of the PPP initiative amongst stakeholders. Indeed, the fact that His Excellency the President of the United Republic of Tanzania recognized malaria as one of his priority agenda's is apparent when he made a plea at the World Economic Forum to channel the savings from debt relief towards the purchase of mosquito nets . The problem was the consultative or non-consultative process that the country pursued in the delivery of the mosquito nets purchased through these funds .
A series of instructions were received by the NMCP from the GFATM (who were given the task of managing the funds), in relation to the presidential initiative. The GFATM desired the funds to be used for quick wins, high visibility and high profile. The Executive Director of GFATM at the time suggested saturating an area of high malaria transmission with at least one LLIN per family to demonstrate a big measurable impact . But the country took a different approach. The NMCP was engaged in rapid planning for the funds with the Tanzania National Coordinating Mechanism, who in turn were receiving pressure from the President's office, the Prime Minister's office and the MoH to finalize the proposal for the initiative. Finally a decision was made to deliver free LLINs to two regions with the highest poverty rates and infant mortality.
Notably, the Presidential initiative had turned the malaria agenda into a crisis event. The stakes were high, there was high visibility and there was a lot of uneasiness not only for the domestic net manufacturers who had invested heavily in the production of mosquito nets but amidst the members of the NATNETs steering committee as well. The institutions the steering committee members belonged to had availed considerable grants towards the PPP approach in the delivery of nets in the country. One member of the steering committee was quoted as follows '...we have been mandated by the Ministry of Health to advise the government on matters related to scaling up of ITNs in Tanzania, but in this Presidential initiative, we have been left out...'. Members of the steering committee, who were mostly from the bilateral organizations such as the UK Department for International Development, the Swiss Development Cooperation, the Development Cooperation for Ireland and the Royal Netherlands Embassy became moderate/poor supporters of the programme in this phase of the implementation of the scheme (Figure 3) and had low influence on the events around them (Figure 6).
As for the net manufacturers, they were really desperate and wrote a memorandum straight to the RBM Secretariat in Geneva reiterating their fears with regards to the agreements that the manufacturers had been enforced with the government on the PPP approach (Figures 3 and 6). The RBM Secretariat responded by carefully outlining that this was a 'one-off' event and the country would not abandon its core strategy in the delivery of mosquito nets.
In the few months that the grant for implementing the President's initiative was being handled by the NMCP, constraints were also observed between the NMCP and UNICEF. In spite of the fact that this multilateral organization had bridged the gap in a very timely manner when the grant funds from the World Economic Forum were delayed, they strongly urged the NMCP to make provision towards the delivery of free nets (Figure 3). However, the MoH was reluctant to change their ITN policy due to a one-off initiative of free delivery of nets in two regions. A number of issues are drawn out through the free delivery of nets in this Presidential initiative: (1) implementation of the policy was in the hands of many different groups and mostly influential figures in the government including the Head of State, (2) there was conflict as the delivery mechanism of nets in the country is changed, (3) the outcome of the conflict was being felt in the public arena, (4) the malaria agenda was turned into a macro-political issue characterized with high stakes, high visibility, in which the government takes complete control in driving the agenda with little or no consultation with other stakeholders, (5) the timing of the initiative was crucial as the funds had to be spent quickly and make a visible impact.
Once all the plans were in place and implementation was underway, the MoH stepped back and called upon its malaria stakeholders to expound the fact that the free net delivery carried out in Lindi was a one-off Presidential initiative, which was beyond their control. They also assured their partners that the mainstay of the Ministry's delivery mechanism was the PPP initiative approach.
The challenges observed by the contractors who were operating the scheme allude to the fact that once policy is formulated, implementation can take on a different angle from the initial goal depending on the bureaucrats at the grass root level . This was reinforced by the focus group discussions where only 60% of the women who were eligible to receive their vouchers actually acquired it. They also underestimated the magnitude of the work and the difficult terrain that features in some districts in the country.
The poverty index in the cohort of women of child-bearing age, which were followed up in the two cycles of the cross-sectional survey, reveal that the most poor are still disadvantaged in redeeming their vouchers for a net. In the monitoring and evaluation household surveys conducted in 2006, it was observed that the least poor women and those living in early launch districts were more likely to have reported receipt of pregnancy voucher than the most poor women and those living in the late launch districts.
A cross-sectional survey carried out in Rufiji in 2005, with a large sample size to observe the contribution of various delivery mechanisms to net use by socio-economic status, was very significant . Net coverage was far higher for the least poor with more than 80% of the better off quintile possessing a net. In the least poor quintile, over half obtained their nets from the commercial market at full price (the most popular source of nets for all other socio-economic groups). Monitoring studies showed that coverage of the three intermediate wealth quintiles was relatively even, coverage of the poorest was consistently and substantially lower for both voucher subsidized and freely distributed nets. Notably the study has also shown that the issue of inequity where subsided mechanisms are used for delivery of goods also applies to goods delivered free of charge. The larger cross-sectional survey study in Rufiji observed that the majority of nets used by infants were obtained through the national voucher scheme and nets provided free to the end user during the child vaccination campaign supported by the Red Cross. Net coverage achieved amongst young children was 50% and over 30% of coverage amongst older children . Clearly the mix of catch-up and keep-up strategies in this very poor rural setting has substantially increased the coverage of mosquito nets in discrete populations of the community in a very complementary manner. The RBM working group on scalable malaria vector control (WIN) underscores that 'for targeted distribution – a single mass distribution catch-up campaign followed up by a continuous delivery system integrated into the ANC and EPI catch-up strategy should rapidly achieve and sustain control coverage levels in excess of 80% without the need of further campaigns... .'
Tanzania took a bold step in the implementation of a country-wide voucher scheme for the delivery of ITNs through a PPP approach to vulnerable groups. The stakeholders had no 'blue-print' in the venture and had to gain experience as the scheme evolved. The challenges they encountered articulated in this synthesis lend invaluable lessons to malaria endemic countries: (a) the consistency of the stakeholders with a common vision to their desired goals is an important strength in overcoming obstacles, (b) senior politicians will often drive the policy agenda when the policy in question is a 'crisis event', the stakes are high and there is high visibility, (c) national stakeholders in policy making have an advantage in strengthening alliances with international organizations, where the latter can become extremely influential in solving bottlenecks as the need arises, and (d) conflict can be turned into an opportunity as the Presidential initiative has lent Tanzania a learning ground in 'catch-up' campaigns, which had not been carried out at that scale in the country. The outcome is a hybrid of mechanisms including catch-up and keep up in the newly developed National Malaria Control Strategic Plan 2008 – 2013 .
The United Republic of Tanzania in congruence with its PPP policy has invested heavily in the scale-up of LLINs in the A-to-Z net manufacturing company in Arusha, where in 2005 it contributed to the building of a new tarmac road to the plant, including the installation of electricity and water. This was to the tune of about 2.5 million USD (Anuj Shah, personal communication). The country has been consistently positive in the PPP approach to ITNs as seen from 2000 when His Excellency the President of the URT, at a fund raising dinner for the comprehensive malaria control project in Zanzibar had this to say ..."I must caution however, that all political will to fight malaria notwithstanding, we can only succeed to meet our goals if there is active participation and support of all stakeholders ."
