Alfred Sommer is a professor at the Johns Hopkins Bloomberg School of Public Health, and was involved in discovering vitamin A’s importance in infectious disease. His CV reads:
"In a series of complex intervention trials Sommer conducted in
To prove these observations definitively, Sommer and his colleagues ran a number of large-scale, community-based, randomized trials from 1983 through 1992 and demonstrated the link between even mild vitamin A deficiency and pediatric mortality.
Moving from science to practice, Sommer next showed that the debilitating consequences of vitamin A deficiency could be effectively, quickly, and cheaply treated with oral high-dose vitamin A supplementation, and treatment did not require a sterile injectable preparation. As a result, the World Development Report (World Bank) declared vitamin A supplementation one of the most cost-effective of all health interventions.
The latest research by Dr. Sommer and his colleagues has shown that supplementing women of childbearing age with vitamin A or beta-carotene can reduce maternal mortality by an average of 45 percent. These dramatic results are now being tested in a new, large, randomized, controlled, field trial in
