Incomplete immunization in Woliso Town is 16% in 2021/22 which is aboveNational cutoff of point <5%, but no justification had been sort out for this high incomplete immunization in the area. Objective:This study aimed to assess the prevalence of incomplete immunization and associated factors among children aged 12-23 months in Woliso town, Ethiopia, 2023 Method: A community based cross-sectional study was conducted among randomly sampled 286children aged 12-23 months in Woliso town from March 06, 2023 to April 06, 2023.The data was collected using pre-tested and structured questionnaire through face to face interview. Data entry and analysis were made using EPI info version 7 software and SPSS version 20 respectively. Association between dependent and independent variables was tested in bivariate and multivariate binary logistic regression model and variables with p-value ≤ 0.25 were entered once stepwise backward in to multivariate logistic regression. Summary results were presented using frequency table and cross- tabulation. Statistical significance was declared at P-value ≤ 0.05 in multivariate logistic regression. Adjusted odds ratio with corresponding 95% CI was used for the interpretation purpose. Result: A total of 284 respondents were enrolled into this study giving a response rate of 99.3%. Fifty-two (18.3%, 95% CI:14.1, 22.5) of children incomplete their immunization. Not having ANC follow up (AOR=4.14, 95%CI: 1.57, 10.90), giving birth at home (AOR=6.52,95%CI: 2.48,17.14), not knowing benefit of vaccination (AOR=3.59, 95% CI: 1.13,11.45), fail to know when to complete immunization of children(AOR= 3.59, 95% CI:1.13,11.45) and not getting advice on next appointment from health workers( AOR=3.58, 95%CI: 1.12,11.46) were statistically associated with incomplete immunization Conclusion:Fifty-two (18.3%, 95% CI:14.1, 22.5) of children incomplete their immunization out of total 284. Not having ANC follow up,giving birth at home,not knowing benefit of vaccination, fail to know when to complete immunization andnot getting advice on next appointment from health workers were statistically associated with incomplete immunization.
