Why was the rotavirus vaccine suspended then reinstated?
In July 1999, the Centers for Disease Control and Prevention suspended the only approved vaccine for rotavirus (a common virus which causes severe diarrhea), saying there was a potential health risk of a serious intestinal problem. In 2006, the CDC’s Advisory Committee on Immunization Practices (ACIP) recommended a newly designed vaccine for infants. The ACIP made its recommendation after reviewing a study involving 70,000 children in which the vaccine showed no association with the previous one’s risks. In February 2007, the CDC adopted the new Rotavirus vaccine in its immunization schedule.
