Predictors of incomplete childhood vaccination in four West African countries: a population based cross-sectional study
摘要
Children with incomplete vaccination are at higher risk of contracting Vaccine-Preventable Diseases and can contribute to the spread of outbreaks. This study assessed the prevalence and predictors of incomplete vaccination among children aged 12–23 months in four West African countries. Using data from the latest DHS of these countries and a weighted sample of 11,333 children, multivariable logistic regression analysis was performed, with a p-value of < 0.05 considered statistically significant. The pooled prevalence of incomplete vaccination was 67%. The odds of incomplete vaccination were lower among children whose mothers attended antenatal clinics (AOR 0.46; 95% CI: 0.39–0.54), were educated (AOR 0.54; 95% CI: 0.47–0.63), and were employed (AOR 0.88; 95% CI: 0.79–0.99). Facility delivery (AOR 0.85; 95% CI: 0.74–0.97), higher household wealth (AOR 0.85; 95% CI: 0.73–0.98), and older maternal age (AOR 0.69; 95% CI: 0.56–0.86) were all associated with reduced odds of incomplete vaccination. In conclusion, the study reveals a high prevalence of incomplete vaccination emphasizing the need for targeted interventions to address identified barriers and improve coverage. We recommend implementing programmes and policies to address country-specific and regional level predictors of incomplete vaccination.
