Antibody results in Plasmodium falciparum circumsporozoite protein enzyme-linked immunosorbent assay (A), automated immunofluorescence assay (B), and automated inhibition of sporozoite invasion assay (C) or ELISA, aIFA, and aISI, respectively. Nets were obtained by subtracting pre-immune values from the values obtained from sera drawn 2 weeks after the third dose of 1·8×106
