Proportions of adequate antibody concentrations or titers to the EPI vaccines and geometric mean concentrations or titers for antibodies against measles, DTwP and TOPV antigens, according to the HIV status of the children.

*P1: P value for the comparison of the proportion of adequate antibody concentrations or titers between HIV-infected and HIV-exposed uninfected children (Chi square test or Fisher exact test, as appropriate)
†P2: P value for the comparison of the GMC between HIV-infected and HIV-exposed uninfected children (Mann-Whitney test)
‡GMC = geometric mean concentration and CI = confidence interval, expressed in mUI/ml, except for poliovirus (UI/ml) and pertussis (GMT).
