Partial vaccination and associated factors among children aged 12–23 months in eastern Ethiopia

Abstract

Abstract Background Vaccine prevents about 2–3 million deaths from vaccine-preventable diseases each year. However, immunization coverage in Ethiopia is lower than the herd immunity level required to prevent the spread of all vaccine-preventable diseases. Thus, this study aimed to assess the partial immunization and associated factors among 12–23-month-old children in Eastern Ethiopia. Method A community-based cross-sectional study design was carried out among 874 randomly selected mothers/caregivers of children aged 12–23 months. A structured questionnaire was adapted and data were collected through face-to-face interviews and review of vaccination cards. Data were coded and analyzed using the Stata version 14 software. A binary logistic regression model was utilized to identify the determinant factors. The predictor of partial immunization was presented by an adjusted odds ratio with a 95% confidence interval. A p-value of 60 min to reach nearby health facilities [AOR = 1.94, 95% CI: 1.1–3.45], [AOR = 4.5, 95% CI: 2.47–8.15], and [AOR = 3.45, 95% CI: 1.59- 7.48] respectively were factors significantly associated with partial vaccination. Conclusions The prevalence of partial immunization is high compared to other studies. As a result, to decrease the proportion of defaulters and to increase immunization coverage, maternal health care utilization like antenatal care follow-up and mother knowledge about the importance of the vaccine need to be sought cautiously.
