Vitamin A Supplementation With Routine Childhood Vaccines and Mortality and Morbidity

Summary

Vitamin A supplementation (VAS) is important for the immune system and may interact with different childhood vaccinations. We have hypothesized that the improved survival after VAS may depend on vitamin A amplifying the non-specific immune modulation induced by vaccinations. In the present study we used information collected in connection with a national vitamin A campaign in Guinea-Bissau during which different doses of VAS was provided together with missing doses of DTP, OPV, and measles vaccines. We aimed to study the potential interactions between VAS and vaccine type.
