Determinants of full valid vaccine dose administration among 12-32 months children in Ethiopia: Evidence from the Ethiopian 2012 national immunization coverage survey

Introduction: According to the 2012 national immunization coverage survey report of Ethiopia, EPI coverage by antigen is 79.6% for BCG, 80.0% for DPT-HepB-Hib1 90.1% for OPV1 65.7%; for adjusted DPT-HepB-Hib 3; 65.7 % for OPV3 and 68.2% for Measles. Similarly, the prevalence of full vaccination was 50%. However, the prevalence of valid vaccination dose for all vaccines is 18.6 %. Therefore, the aim of this study is to identify factors that determine the administration of full valid vaccines dose to set effective interventions.Methods: Data was obtained from the 2012 Immunization Coverage survey of Ethiopia, a cross- sectional study administered at the household level. Data were analyzed using SPSS version 20. Binary and multivariate logistic regression with 95% CI was done to assess factors associated with getting full valid vaccination dose. Results: As documented from the 2012 national immunization coverage survey, the coverage of full valid vaccination dose were very low as compared to full immunization coverage that is 18.6% Vs 50%, respectively. Urban residence 2.6 (95% CI: 2.50, 2.68), mothers with age groups of 21-34 and >35 were 1.26 (95% CI: 1.22, 1.29) and 2.4 (95% CI: 2.3, 2.44); children with caretakers with primary, secondary, and higher level of education were 1.6 (95% CI: 1.22, 1.29), 2.8 (95% CI: 2.76, 2.92), and 2.2 (95% CI: 2.13, 2.27) times more likely to get valid vaccination dose.Conclusion: The rich wealth quintile, rural place of residence, living more than 5km proximity to nearest health facility, having more than six sibling, having teenage (
