Last week, the World Health Organization recommended that a vaccine against the rotavirus, a diarrheal disease that takes the lives of half a million children per year, be administered to every child around the world. The recommendation came after a studies done in South Africa and Malawi showed that the vaccine is effective even in areas of poor sanitation. The Bill and Melinda Gates Foundation paid for most of the research. Unfortunately, this would not be an easy task- the vaccine costs about $20 even in poor countries, and it must be refrigerated. This poses some difficulties with issuing the vaccine to every child in the world.
