Indicators are within children aged 12–23 months at the time of the survey, except for LLIN use, which is within children aged 5–48 months. To assess whether vaccine introduction was associated with any change in coverage of other vaccines, coverage of LLIN use, care-seeking for fever, or use of vitamin A, the ratio of the prevalence in the midline survey to that at baseline was compared between implementing and comparison areas. The relative ratio (ratio of the prevalence ratio in implementing areas to that in comparison areas) is shown in the forest plots. *Ratio of prevalence ratio of pre-introduction and midline surveys. Equivalent numbers restricted to the sentinel areas are available in theappendix (p 59). †Vaccination coverages in Ghana are from HBR only in the baseline survey because vaccination status by recall was not captured; midline coverages presented are from HBR or recall; however, for comparability, the prevalence ratios for midline versus baseline surveys in Ghana use coverage by HBR only. ‡Full basic vaccination coverage refers to BCG at birth, three doses of OPV (excluding birth dose), three doses of the pentavalent vaccine, and one dose of the measles vaccine; children who received IPV at 14 weeks in place of the third dose of OPV were considered to be fully vaccinated for polio; IPV status was only available from recall in Malawi, only available from HBR in Ghana, and not available in Kenya by either method. §Vitamin A coverage was determined from HBR only in Ghana, recall only in Malawi, and both HBR and recall in Kenya. HBR=home-based record. LLIN=long-lasting insecticide treated-net. RTS,S=RTS,S/AS01Emalaria vaccine. OPV=oral poliovirus vaccine. IPV=inactivated poliovirus vaccine.
