Title: Should Infants Receive High-dose Vitamin A Supplementation With BCG Vaccine at Birth in Developing Countries?
Brief Summary: Two studies from Asia have suggested a beneficial effect of vitamin A supplementation given at birth. Hypotheses: Vitamin A supplementation administered at birth together with BCG vaccination is associated with a 30% reduction in infant mortality and morbidity during the first year of life in normal birth weight children in an African setting.
