Community vaccine perceptions and its role on vaccination uptake among children aged 12-23 months in the Ileje District, Tanzania: a cross section study

INTRODUCTION: Underutilization of vaccines still remains a challenge in many regions across the world. Ileje district is one of the districts in Tanzania with consistently low pentavalent vaccine uptake (69%) and with drop out of 15%. We determined the vaccination completion with regard to Oral Polio virus, Measles, Bacillus Calmette-Guérin, and pentavalent vaccines and its association with community perceptions on vaccines. METHODS: We conducted a cross sectional study in Ileje district from October to December 2013. We sampled 380 mothers using a multistage random sampling technique. We analysed data using EPI INFO. We summarized descriptive variables using mean and standard deviation and categorical variables using proportions. We conducted bivariate and multivariate logistic regression to identify factors influencing vaccination uptake, statistical significance was assessed at 95% confidence interval. RESULTS: Mean age of the mothers was 27 years (SD 6.5 years) while that of their children was 16 months (SD 3.6 months). Fully vaccinated children were 71.1% and partially vaccinated were 28.9%, 99.2% were vaccinated with BCG vaccine and 73.4% were vaccinated with all OPV vaccine. Predictors of vaccination completion included negative perception on the vaccine provider-client relationship (AOR 1.86, 95%CI1.03-3.35), Perceived satisfaction with vaccination services (AOR 2.63, 95%CI 1.1 - 6.3). Others include child being born in the health facility (AOR 13.8 95% CI 8.04-25.8) and younger age of a child (AOR 0.51, 95%CI 0.29-0.9). CONCLUSION: Improving quality of vaccination services, promoting health education and sensitizing community on health facility delivery will improve child vaccination completion in the district
