Vitamin A Supplementation With Bacille Calmette Guerin (BCG) Vaccine

Summary

In the present study the investigators wish to address the effects of different doses of vitamin A supplementation in low and normal birth weight infants. 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 both normal and low birth weight infants. * A lower dose of vitamin A may be even more beneficial than a high dose.
