The Centers for Disease Control and Prevention’s vaccine advisory group is considering changing recommendations for the MMRV and hepatitis B vaccines. CDC staff presented evidence showing a slightly increased risk of fever-related seizures in children ages 12-23 months associated with the MMRV shot compared to the MMR, which concerned some committee members. The meeting comes on the heels of a contentious Senate hearing on Wednesday with the recently-ousted CDC director Susan Monarez. Monarez testified that she was fired after clashing with Kennedy over his demands that she preemptively agree to approve vaccine recommendations from ACIP, and fire career scientists. “He said the childhood vaccine schedule would be changing starting in September and that I needed to be on board with it,” Monarez said.
