The panel of vaccine advisors hand-selected by anti-vaccine activist Robert F. Kennedy Jr. voted on Thursday to change the federal vaccine recommendations for children, removing safe, well-established vaccine doses from current schedules and realizing Kennedy's anti-vaccine agenda to erode federal vaccine policy and sow distrust. Specifically, the panel—the Advisory Committee on Immunization Practices (ACIP)—voted to remove the Centers for Disease Control and Prevention's previous recommendation for use of a measles, mumps, rubella, varicella (chickenpox) MMRV combination vaccine for children under 4 years old. The context In June, Kennedy fired all 17 highly qualified, highly vetted members of ACIP and quickly replaced them with seven questionable members, who largely did not have subject matter expertise. Moreover, many of them have clearly expressed anti-vaccine rhetoric and skepticism about pandemic responses and COVID-19 vaccines. At least two new members have been paid witnesses in trials against vaccine makers, a clear conflict of interest. Earlier this week, Kennedy added five additional members, who raise the same anti-vaccine concerns as the first group. In the meeting today—the first of two all-day meetings—members made clear their inexperience and lack of expertise in evaluating vaccine policy. They asked basic questions about study data and analysis—such as asking what a "low confidence" designation means—and claimed CDC presentations lacked critical data when, in fact, a CDC scientist had just presented the exact data in question. The first half of the day focused on the MMRV vaccine, while the second half focused on a newborn dose of the hepatitis B (hep B) vaccine. A vote was initially scheduled for that vaccine today, too, but was postponed after the panel decided to change the wording of the voting question. They meet again tomorrow to vote on the hep B recommendation as well as recommendations for this year's COVID-19 vaccine. Ars Technica will have coverage of the second half of the meeting tomorrow, along with a report on the hepatitis B discussion today. MMRV vaccine change For the MMRV vaccine, the panel rehashed an issue that vaccine experts had thoroughly examined years ago. Currently, the CDC recommends children get vaccinated against measles, mumps, rubella, and varicella (chickenpox) twice—one dose at 12 to 15 months, and a second dose between the ages of 4 and 6 years.
