刚在美国网站上查的信息，今年5月14号的，说是没问题。
Within the last two months, FDA became aware of the presence PCV1 in Rotarix and DNA from PCV1 and PCV2 in RotaTeq. These viruses are not known to cause any infection or illness in people.
Based on a careful review of a variety of scientific information, FDA has determined it is appropriate for clinicians and public health professionals in the United States to use these vaccines. All available evidence supports the safety and effectiveness of Rotarix and RotaTeq, which have been extensively studied, both before and after approval.
FDA = US FOOD AND DRUG ADMINISTRATION
