Plasmodium falciparum age-seroprevalence curves for the entire study site (a) and distinct geographical regions within each study site (b, c). Seroprevalence curves, fitted by maximum likelihood, represent the average annual rate at which this population become seropositive to either PfAMA-1 and/or PfMSP-119 characterized by a seroconversion rate (SCR). Red triangles: observed age-seroprevalence, solid lines: predicted seroprevalence and dotted lines: predicted seroprevalence upper and lower 95% confidence intervals. N: sample size
