Effect of prenatal maternal parasitic infection on prevalence of protective infant anti-vaccine IgG levels at 6 and 24 months of age.

The upper panel (A) indicates results at 6 months of age. The lower panel (B) indicates results at 24 months of age. Open circles indicate the proportion of children of mothers uninfected during pregnancy who had protective antibody levels against each of vaccine antigens tested in this study. Antigens are arrayed along the x axis; error bars indicate the 95% CI of the observed prevalence values. Open boxes indicate results for children of mothers who had any antenatal parasite infection, and black boxes indicate results for children whose mothers had two or more infections during pregnancy. Numerical details are presented in S1 Table.
