Age-stratified IgG and IgM responses. Antibody responses: IgG responses against MSP3 (a) and Pfs230 (c) and IgM responses against MSP3 (b) and Pfs230 (d) in the study participants were stratified into children 10 years old and below (≤ 10 years), children between 11 and 15 years (11–15 years) and adults 16 years and above (≥ 16 years). Measurements were made in both the dry and rainy season from Obom and Asutsuare. Antibody concentrations are presented in arbitrary units (AU) on a Tukey box-and-whiskers plot
