The study sought to examine the predictors of incomplete vaccination against polio among children aged 12\u201323 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\u2019 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\u2019s incomplete polio vaccination and\/or vaccination dropout.<\/jats:p>","DOI":"10.3390\/ijerph182211820","type":"journal-article","created":{"date-parts":[[2021,11,11]],"date-time":"2021-11-11T23:02:41Z","timestamp":1636671761000},"page":"11820","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Bayesian Analysis of Predictors of Incomplete Vaccination against Polio among Children Aged 12\u201323 Months in Ethiopia"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1324-2135","authenticated-orcid":false,"given":"Teshita Uke","family":"Chikako","sequence":"first","affiliation":[{"name":"Wondo Genet College of Forestry and Natural Resource, Hawassa University, Hawassa P.O.
