Background Information Immunization is one of the most cost-effective public health interventions to address the morbidity and mortality attributable to vaccine-preventable diseases. However, predictors of immunization completion have not been well studied in Kwania. This study investigated predictors of immunization completion among children aged 12-23 months old in Kwania. Methods: This was a cross-sectional study design, a sample size of 409 children aged 12-23 months was considered. A multistage sampling technique was employed to select the study subject. Data was entered into SPSS version 23; univariate and multivariate logistic regression models were used to identify the association between the variables. A P-value <0 .05 was considered statistically significant at 95% CI. Results: Out of 409 children paired with their mothers, 77.3% completed their immunization. 89% of the caregivers had health cards and 91.2% at least attended ANC. Predictors of complete immunization in this study were; the presence of a health card (AOR: 1.57, P = 0.01), the child aged 16-20 months and above 20-23 months (AOR: 2.34, P = 0.01), and (AOR=4.07 p=0.00) respectively, ANC attendance (AOR: 2.01, P = 0.02) and positive attitude of health workers (AOR: 2.36, P = 0.01). Conclusion: Immunization completion among children aged 12-23 months in Kwania was 77.3%, below the national target of 90%. The child’s age, health cards, ANC attendance, and positive attitudes of health workers were associated with immunization completion. Therefore, the district stakeholders should mobilize the community to improve ANC attendance, provide health cards during vaccination, and innovate other strategic interventions to address adherence to immunization completion.
