Yellow fever vaccine coverage and associated factors among under-five children in Kenya: Data from Kenyan Demographic and Health Survey 2022

Abstract

Yellow fever is a vaccine preventable hemorrhagic disease that leads to morbidity and mortality in the affected individuals. The only options for preventing and controlling its spread are through vaccination. Therefore, this study was conducted to estimate yellow fever vaccination coverage and associated factors among under-five children in Kenya. The total weighted samples of 2,844 children aged under-five were included in this study. The data were taken from the Kenyan Demographic and Health Survey 2022. In the multivariable analysis, the adjusted odds ratio with a 95% CI was used to declare significant associations of yellow fever vaccine. The yellow fever vaccine coverage among children aged under-five in Kenya was 18.50%. The significant factors associated with yellow fever vaccine coverage were: the age of the child older than 24 months (AOR = 1.7; 95% CI (1.17–2.58)); higher odds of yellow fever vaccination coverage was observed among older children, place of residence (AOR = 1.76; 95% CI (1.04–2.97)); higher odds was observed among urban residents, maternal education; primary education (AOR = 1.99; 95% CI (1.04–2.97)), secondary education (AOR = 2.85; 95% CI (1.41–5.76)), mothers who attended primary or secondary education have higher odds of yellow fever vaccination coverage, wealth index (AOR = 2.38; 95% CI (1.15–4.91)); higher odds of vaccination coverage was observed among poor households. Yellow fever vaccine coverage among under-five children in Kenya was low and has become an important public health concern. Policymakers and other stakeholders are recommended to focus on vaccination programs to prevent yellow fever disease.
