摘要

Background

The conflict in Tigray led many children to remain unvaccinated or under-vaccinated, thus, after the Pretoria peace agreement an integrated supplementary immunization activity was carried out to reach these children. Therefore, this study aimed to investigate the coverage and identify the factors affecting the uptake of integrated measles supplementary immunization activities in the post-conflict setting of Tigray, northern Ethiopia.

Methods

A community-based cross-sectional study design was conducted from July 1–30, 2023 and the data were collected from mothers or caregivers of children aged 0–59 months. The study participants were selected using a multi-stage sampling technique. Descriptive analysis was employed and the results were presented using tables and figures. A modified Poisson regression analysis was performed to examine the relationship between the independent and dependent variables.

Results

The overall coverage of measles vaccination among children aged 6–59 months during the Integrated Measles Supplementary Immunization Activities (IMSIAs) campaign was 90% (95% CI: 89%, 90%). The significant predictors for measles vaccination during the IMSIAs campaign were maternal age, those aged 25–34 years (Adjusted Prevalence Ratio (aPR): 1.03; 95% CI: 1.01, 1.06), and aged 35 + years (aPR: 1.07; 95% CI: 1.05, 1.10), receiving information about the campaign (aPR: 3.68; 95% CI: 2.98, 4.54) and perceived wealth status of mothers, moderate in wealth (aPR: 0.95; 95% CI: 0.92, 0.99) or poor (aPR: 0.95; 95% CI: 0.92, 0.98).

Conclusion and recommendation

The integrated measles supplementary immunization activities successfully reached a significant number of children who were previously unvaccinated or under-vaccinated during the conflict in the Tigray region. Despite this progress, a considerable number of children remained unvaccinated. Thus, it is crucial to conduct periodic supplementary immunization activities and catch-up vaccinations in the most affected and hard to reach districts of the region.
