COVID-19 concerns among caregivers and vitamin A supplementation coverage among children aged 6-59 months in four countries in Western sub-Saharan Africa.

Objective: To assess child vitamin A supplementation (VAS) coverage in 2019 and 2020 and explore key factors, including COVID-19 concerns, that influenced VAS status in four sub-Saharan African countries.

Design: Data from eight representative household surveys were used to assess VAS coverage. Multivariable logistic regression models examined the effect of rural/urban residence, child sex and age, caregiver education, COVID-19 concern and household wealth on VAS status.
