FDA Tells Physicians to Temporarily Stop Using Rotarix Vaccine

The FDA is advising clinicians to temporarily stop using the rotavirus vaccine Rotarix because components of a separate virus, porcine circovirus 1 (PCV1), have been detected in the vaccine.
PCV1 is not known to cause illness in humans, and according to FDA Commissioner Dr. Margaret Hamburg, "there is no evidence at this time that there is a safety concern."
The agency says that children who've already received one dose of Rotarix can receive RotaTeq instead for the next two doses to complete the series.
The FDA will continue to investigate the finding and expects to make additional recommendations on the use of rotavirus vaccines after an expert advisory committee meets in about 4 to 6 weeks.
