WASHINGTON (AP) -- A vaccine against a virus that hospitalizes thousands of children in the U.S. with diarrhea and kills millions in developing countries moved a step closer to the U.S. market on Wednesday.
If the government gives the go-ahead, Merck & Co.'s vaccine would become the nation's second attempt at preventing rotavirus. A competitor's vaccine was pulled from the market six years ago because of a rare but life-threatening side effect.
Federal health advisers unanimously voted Wednesday that Merck's candidate, RotaTeq, seems safe and effective. They also urged careful monitoring to watch for that side effect, a twisted bowel condition, and other possible problems.
