  1. * MiP is a consortium of experts in the field of malaria funded by the Bill and Melinda Gates Foundation to review current research and develop future research strategy for malaria in pregnancy. One of the key objectives of MiP is to create a database containing all published and unpublished research and a trial registry on malaria in pregnancy.
