Determinants of immunization status among 12–24 months old children in Ethiopia: Using 2019 Ethiopian mini demographic and health survey data

Abstract

Background Vaccination is a global success story, one of the most effective and successful health interventions for health and development, saving the lives of millions of children every year. In 2018, nearly 870,000 Ethiopian children did not receive the life-saving measles, diphtheria, and tetanus vaccines. This study aimed to determine what factors influence children’s immunization status in Ethiopia. Methods Immunization status was examined in a sample of 1843 children aged 12–24 months using data from the 2019 Ethiopian Mini Demographic and Health Survey 2019. The study used percentages to show the prevalence of immunization status among children. The marginal likelihood effect was used to determine the impact of each category of the explanatory variable on one response category of immunization status. Ordinal logistic regression models were constructed, and the best-fitting model was selected to identify significant immunization status variables. Results The immunization prevalence among children was 72.2% (34.2% fully immunized and 38.0% partially immunized), while about 27.8% of children were non-immunized. The fitted partial proportional odds model revealed that child immunization status was significantly associated with region afar (OR = 7.90; CI: 4.78–11.92), family planning use (OR = 0.69; CI: 0.54–0.88), residence (OR = 2.22;CI: 1.60–3.09), antenatal visit (OR = 0.73;CI: 0.53–0.99), and delivery place (OR = 0.65;CI: 0.50–0.84). Conclusions Vaccinating children was a significant step forward in improving and protecting child health in Ethiopia, as the proportion of non-immunized children was about 27.8%. The study showed that the prevalence of non-immunization status among rural children was 33.6% and about 36.6% among children from non-educated mothers. As a result, it is agreeable that treatments are better to focus on targeting essential childhood vaccinations by promoting maternal education about family planning, antenatal visits, and maternal access to health care.
