Pig virus found in Merck rotavirus vaccine-U.S. FDA

WASHINGTON, May 6 (Reuters) - Pieces of DNA from two pig viruses were found in Merck & Co Inc’s (MRK.N) rotavirus vaccine, but there was no evidence of a safety risk, U.S. health officials said on Thursday.

The finding follows a March announcement of an apparently harmless pig virus found in a rival rotavirus vaccine from GlaxoSmithKline Plc (GSK.L). (Editing by Maureen Bavdek)
