National age-seroconversion plots for antibody responses for Plasmodium falciparum and Plasmodium vivax antigens [Merozoite Surface Protien-1 (MSP-1) and Apical Membrane Antigen-1 (AMA-1)]. Y-axis represents probability of being seropositive and the X-axis age. Seroconversion curves represent the rate at which a population becomes seropositive to specific antigens resulting in seroconversion rates (SCR) or lambda (λ). In each graph points represent age seroprevalence (by deciles), unbroken line represents maximum likelihood curves and broken lines represent the 95% confidence interval. a and d depict the seroconversion rates for combined (MSP-1/AMA-1) P. falciparum antigen response (a) and for combined (MSP-1/AMA-1) P. vivax antigen response (d). Plots b and c show seroconversion rates for individual P. falciparum antigens MSP-1 (b) and AMA-1 (c). Plots e and f show seroconversion rates for individual P. vivax antigens MSP-1 (e) and AMA-1 (f)
