Demographical, clinical, and complication differences between vaccinated and unvaccinated hospitalized children with measles in mogadishu somalia: a hospital-based retrospective cohort study

Abstract
Background:
Measles is endemic in Somalia; recurrent outbreaks are reported annually. Under-five children are the most affected due to low immunization coverage, vitamin A deficiency, and malnutrition. The study aims to evaluate the demographical, clinical, and complication variations between vaccinated and unvaccinated hospitalized children with measles in the study hospital.

Method:
A hospital-based retrospective cohort study was implemented between 10 October and 10 November 2022 by reviewing case record files following a well-structured checklist of admitted clinical features, demographic characteristics, history of measles immunization, and measles complication status. Descriptive statistics were used by presenting frequency and percentage for categorical and the mean score for continuous variables. χ2 and Fisher’s exact test at P =0.05 were used to identify the proportions differences between vaccinated and unvaccinated cases.
