Determinants of full valid vaccine dose administration among 12-23 months children in Ethiopia: evidence from the Ethiopian 2012 national immunization coverage survey

Abstract

Introduction:- According to the 2012 national immunization coverage survey report of Ethiopia, the EPI coverage by antigen is BCG 79.6% , DPT-HepB-Hib1 80.0%; OPV1 90.1%; adjusted DPT-HepB-Hib3 65.7%; OPV3 70.5%; and measles 68.2%. Similarly, the prevalence of fully vaccination was 50%. But, 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 from the Ethiopian 2012 national immunization coverage survey to set effective interventions. Methods:- Data was obtained from the 2012 Immunization Coverage survey of Ethiopia. Cross- sectional survey was administered at the household level to provide estimates for infant immunization status at the national 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 :- Urban residence 2.6 (95% CI: 2.50, 2.68), mothers with age groups of 21-34 and >35 were 26% (95% CI: 1.22, 1.29) and 2.4(95% CI: 2.3, 2.44); Childs who had a care takers attended 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 than their counter parts. Conclusion:- Infants who had young mother , had no formal education, mother/ care giver with no card or family folder which state children vaccination status, care takers ever refused to vaccinate their child, and did not hear a message about importance of vaccine were less likely to get full valid vaccination dose.
