Does India Need a Universal High-Dose Vitamin A Supplementation Program?

High dose vitamin A (HDVA) concentrate began to be distributed in India in 1970 as a short-term, stop-gap approach to reduce clinical signs of vitamin A deficiency. As this problem declined globally, the purpose of distributing them changed to the reduction of young child mortality. However, their impact on this has also declined, if not disappeared, as suggested in India by the enormous DEVTA study. This may be because of improved protection against and treatment of the main morbidity involved, measles and diarrhea. At the same time, semi-annual provision of mega-doses of vitamin A is not without risks, in particular linked to children's vaccination status. While a single dose is inexpensive, large-scale implementation of HDVA programs is expensive, particularly the opportunity cost involved in reducing the time health workers involved have to deal with their other commitments. Balancing potential benefits, risks and costs leads us to recommend an immediate cessation of the distribution of HDVA in India.
