Alfred Sommer

Alfred (Al) Sommer (born October 2, 1942) is an American ophthalmologist and epidemiologist at the Johns Hopkins Bloomberg School of Public Health. His research on vitamin A in the 1970s and 1980s revealed that dosing even mildly vitamin A deficient children with an inexpensive, large dose vitamin A capsule twice a year reduces child mortality by as much as 34 percent. The World Bank and the Copenhagen Consensus list vitamin A supplementation as one of the most cost-effective health interventions in the world. Provided by Wikipedia
