Background: The effect of mother’s HIV-status on child vaccination is an important public health issue in countries with high HIV prevalence. We conducted a study in a primary healthcare center located in Niamey, the capital of Niger, which offers free of charge services to HIV positive and/or underprivileged mothers, with the aim of assessing: 1) vaccination coverage for children 0–36 months old, born to HIV-infected mothers, and 2) the impact of maternal HIV status on child vaccination. Methods: Mothers of children less than 36 months old attending the center were interviewed, to collect information on vaccines administered to their child, and family’s socio-demographic characteristics. Results: Overall, 502 children were investigated. Children of HIV-seropositive mothers were less likely to receive follow up vaccinations for Diphtheria-Tetanus-Pertussis (DTP) than those of HIV-seronegative mothers, with a prevalence ratio (PR) of 2.03 (95%CI: 1.58–2.61). Children born to HIV-seropositive mothers were less likely to miss vaccination for MMR than those born to HIV negative mothers, with a RR of 0.46 (95%CI: 0.30–0.72). Conclusions: Vaccine coverage among children born to HIV infected mothers was rather low. It is important to favor access to vaccination programs in this population.
