FDA has learned that DNA from porcine circovirus type 1 (PCV1) is present in Rotarix. PCV1 is not known to cause disease in humans. There is no evidence at this time that this finding poses a safety risk. Because available evidence supports the safety of Rotarix, no medical follow-up is needed for patients who have been vaccinated with Rotarix.
There are two licensed vaccines for rotavirus in the United States: RotaTeq and Rotarix. For children who have received one dose of Rotarix, CDC advises that clinicians can complete the series with RotaTeq for the next two doses.
