Nutrient Needs

If every child received adequate vitamin A supplements, 1 million lives could be saved each year, making it an easy choice for our 100 Objects That Shaped Public Health list.
After studying vitamin A deficiency among poor children in Indonesia in the 1970s, researcher Al Sommer led a randomized controlled trial involving more than 20,000 children. He showed that a 2-cent capsule of vitamin A given twice a year reduced deaths by 1/3rd. The finding was replicated in other studies, leading to the adoption of vitamin A supplementation in more than 70 countries.
Check GHN every Wednesday for an up-close look at one of the objects that made the list published by the Johns Hopkins Bloomberg School of Public Health.
