Seroprevalence of total IgG and subclass response to PfRH5 and PfRipr by concurrent parasitemia measured by PCR.
Results are shown as percentage seropositive, as determined by ELISA. Error bars indicate standard error of proportion (SE). Results are shown by parasitemic status at enrolment (PCR(−) or PCR(+)). Top row: PfRH5 Bottom row: PfRipr. Results are shown for (A)/(D) Total IgG, (B)/(E) IgG1 and (C)/(F) IgG3 left to right. P values indicate chi square test.
