FDA OKs New Vaccine for Kids' Diarrhea

Other Vaccines in the Works

Other rotavirus vaccines are in the works in the U.S. and other countries but have not been approved by the FDA, Goodman notes.

RotaTeq is one of two rotavirus vaccines that were recently called "promising" in The New England Journal of Medicine. The other vaccine, called Rotarix, hasn't been FDA-approved.

An editorial in the journal also stated that "hundreds of thousands of children will need to be immunized before a clean bill of health can be given to these vaccines. The editorialists included the CDC's Roger Glass, MD, PhD.

RotaTeq is made by Merck. Rotarix is made by GlaxoSmithKline. GlaxoSmithKline and Merck are WebMD sponsors.
