Different Doses of Vitamin A and Childhood Morbidity and Mortality

Summary

Vitamin A supplementation reduces all-cause mortality. It is therefore given with oral polio vaccine in national campaigns. However, it is not clear which dose is optimal. The two studies that have investigated the impact of different doses of vitamin A have both found that a smaller dose was better than a large dose. We therefore investigated if a smaller dose given with oral polio vaccine gives equal or better effect.
