Prevalence and determinants of full vaccination coverage according to the national schedule among children aged 12–35 months in Ghana

Abstract Universal immunization of children against common vaccine-preventable diseases is crucial in reducing infant and child morbidity and mortality. Assessing the vaccination coverage is a key step to improve utilization and coverage of vaccines for under-five children. Accordingly, vaccination coverage according to the national schedule assesses the vaccination coverage of children aged 12–35 months. However, there is a scarcity of information on the full vaccination coverage according to the national schedule and its determinants in Ghana. Therefore, this study aimed to assess the prevalence and predictors of vaccination coverage according to the national schedule among children aged 12–35 months in Ghana. A cross-sectional study design using the most recent demographic and health survey data from the Ghana Demographic and Health Survey was used. We included a total weighted sample of 1,823 children aged 12–35 months in the five years preceding the survey. We used a multilevel logistic regression model to identify associated factors for vaccination coverage according to the national schedule in Ghana. The adjusted odds ratio at 95% Cl was computed to assess the strength and significance of the association between explanatory and outcome variables. Factors with a p-value of
