Incomplete immunization and associated factors among children 12-23 months in Aletawondo district, Sidama zone, South Ethiopia: Across-sectional study.

Abstract

Immunization is one of the most cost-effective and commonly used public health strategies for preventing child mortality. The goal of this study was to determine the prevalence of incomplete immunization and associated variables in children aged 12-23 months in the Aleta Wondo district of Southern Ethiopia. The researchers utilized a community-based cross-sectional study approach. A modified World Health Organization-Expanded Program on Immunization cluster sampling method was used to choose 634 mothers/caregivers of children aged 12-23 months. Data were collected by trained data collectors between March and April 2019. Descriptive statistics and logistic regression were done. In this study, 138 (21.8%) of children were not completed their immunization. Mothers who were literate [AOR = 2.1; (95% CI: 1.1, 4.2)]. Home birth [AOR = 2.9; (95% CI: 1.7, 5.3)], walking time from home to vaccination site [AOR = 1.95; (95% CI: 1.1,3.3)], inconvenience times for vaccination service [AOR = 2.4; (95% CI: 1.3,4.5)], postponing vaccination session schedule [AOR = 2.4; (95% CI:1.1,5.4)], households not visited by health extension workers [AOR = 4.1; (95% CI: 2.2,7.4)], poorer knowledge about child immunization [AOR = 4; (95% CI:2.2,7.5)] were factors associated with incomplete immunization. Incomplete immunization was higher compared to the national target. It is necessary to strengthen the program by enhancing the number of outreach sites considering the size of the target group.
