Figure 2. Age sero-prevalence plots for antibody responses to P. falciparum parasite antigens MSP-1₁₉ (fig 2a) and AMA-1 (figure 2b) from the pilot study (Msitu wa Tembo).

Open circles (and confidence limits) represent observed age group specific sero-prevalence points for the cross sectional survey. The dotted line represents a maximum likelihood fit using these data. The full triangles and unbroken line represent observed sero-prevalence points and fitted line for the health facility surveys.
