Bayesian Analysis of Predictors of Incomplete Vaccination against Polio among Children Aged 12–23 Months in Ethiopia

Abstract

Background: The re-introduction of polio among children aged 12–23 months is likely to occur in Ethiopia due to the low vaccination rates against poliovirus. The study sought to examine the predictors of incomplete vaccination against polio among children aged 12–23 months in Ethiopia. Methods: The data used were obtained from the 2016 Ethiopia Demographic and Health Survey. Binary and Bayesian logistic regressions were used for the data analysis, with parameters estimated using classical maximum likelihood and the Bayesian estimation method. Results: The results revealed that 43.7% of the children were not fully vaccinated against polio in Ethiopia. Maternal age, educational level, household wealth index, exposure to mass media, place of residence, presence of nearby healthy facility, counseling on vaccination, and place of delivery were significant determinants of incomplete polio vaccination among children aged between 12 and 23 months in Ethiopia. Conclusion: Considerable numbers of children are not fully vaccinated against polio in Ethiopia. Individual and contextual factors significantly contributed to incomplete polio vaccination among children in the country. Therefore, the government and other stakeholders should pay particular attention to maternal education to increase mothers’ educational level in all regions and give training and counseling in all urban and rural parts of the country on child vaccination to overcome the problem of children’s incomplete polio vaccination and/or vaccination dropout.

“…This may be due to the fact that most mothers who go to Angola give birth at home because the majority live in mining camps, which does not allow them to easily access maternal and child care. Moreover, it has been proven that the place of residence of the mother plays a large role in the complete vaccination of children [24]. It was shown in a study conducted in Ethiopia that children of mothers living in rural areas were more likely to be unvaccinated than those living in urban areas.…”

Particular attention should be paid to disadvantaged mothers by raising awareness about the importance of childhood vaccination [24].…”

“…Although the reason for this finding was not directly collected, we speculate that most mothers who travel to Angola give birth at home because many live in mining camps and do not have access to maternal and child care. Vaccination services in both countries (Angola and DRC) should therefore tailor intervention to reach children in mining camps via mobile or advanced vaccination sessions, as the place of residence of the mother plays a large role in the child's vaccination [24].…”
