Vitamin A supplementation cost-effectiveness questionedCost-effectiveness of Vitamin A supplementation among children in three sub-Saharan African countries: An individual-based simulation model using estimates from Global Burden of Disease 2019.
We explored the effectiveness of Vitamin A supplementation (VAS) in reducing measles-related mortality among children in Nigeria, Kenya, and Burkina Faso. Using a detailed simulation model, we calculated the costs and health benefits of increasing VAS coverage from 2019 to 2023.
While our results showed some reduction in disability-adjusted life years (DALYs), the cost-effectiveness ratios ranged widely—ranging from $220 to $860 per DALY averted. Ultimately, it appears VAS may not be as cost-effective as previously thought, prompting experts to recommend alternative interventions like improved food fortification and vaccination coverage.
