FDA is updating clinicians on information that recently has become available about Rotarix, a vaccine used to prevent rotavirus disease. FDA has learned that components of an extraneous virus, PCV1, are present in Rotarix. There is no evidence at this time that this finding poses a safety risk. While the agency is learning more about the situation, FDA is recommending that clinicians and public health professionals in the United States temporarily suspend the use of Rotarix. FDA will keep the public and the clinical community updated as more information becomes available.
To rephrase this they ‘unexpectedly’ (research was by an independent research team not linked to a vaccine company) found a pork virus in a vaccine we give to young infants. hmm
