(CNN) — Federal health authorities recommended Monday that doctors suspend using Rotarix, one of two vaccines licensed in the United States against rotavirus, saying the vaccine is contaminated with material from a pig virus.
“There is no evidence at this time that this material poses a safety risk,” Food and Drug Administration Commissioner Dr. Margaret Hamburg told reporters in a conference call.
Rotarix, made by GlaxoSmithKline, was approved by the FDA in 2008. The contaminant material is DNA from porcine circovirus 1, a virus from pigs that is not known to cause disease in humans or animals, Hamburg said.
About 1 million children in the United States and about 30 million worldwide have gotten Rotarix vaccine, she said.
