The Food and Drug Administration told doctors Monday to temporarily stop using the Rotarix vaccine after the product was found to be contaminated with a pig virus.
Rotarix is typically given to infants to protect against potentially deadly gastrointestinal illness caused by rotavirus. The FDA approved the vaccine in 2008.
Researchers recently found DNA from the porcine virus PCV-1 in the vaccine, and that the virus has been present in the product since early in its development, the FDA said in a statement. The agency said there was no evidence that the vaccine had caused any health problems but wants doctors to stop using it until outside medical experts can rule out risks.
Rotarix manufacturer GlaxoSmithKline said in a statement that PCV-1 does not multiply or cause illness in humans. It also said the virus is routinely found in meat products and “frequently eaten with no resulting disease or illness.”
