ROCHESTER, Minn.--(BUSINESS WIRE)--More than half a million children – or 1,400 to 1,600 each day – die from rotavirus, the most common cause of severe childhood diarrhea. Almost all of these deaths occur in developing countries, where lifesaving medical care may not be affordable or available to the families with the most critical needs. In addition, income loss due to the need for parents to take care of sick children can have a very significant economic burden on families that can least afford it. To combat rotavirus, the International Medica Foundation is sponsoring a Phase II clinical trial of its oral rotavirus vaccine, RotaShield®. The trial is being conducted in more than 1,000 infants in Ghana, Africa, in association with the Noguchi Memorial Institute for Medical Research.
