Fig. S1.

Responses to two laboratory Plasmodium falciparum isolates A4 40-cycle and 3D7, and a clinical isolate P1. The proportion of individuals in each age category are shown, with upper 95% confidence interval, scoring positive for antibody recognition of parasite lines A4 40-cycle and 3D7 and clinical isolate P1. Positivity was scored as defined in the text. The dark grey bars represent individuals with no microscopically detectable parasitaemia at the time of the cross-sectional survey and the light grey bars represent individuals with parasites detected at that time. A) responses to A4 40-cycle B) responses to 3D7 C) responses to P1
