With no new data or clear reasoning, a panel of advisors hand-selected by anti-vaccine Health Secretary Robert F. Kennedy Jr. voted last September to strip federal recommendations for a combination shot against measles, mumps, rubella, and varicella (chickenpox). An analysis published today by independent researchers does the work the advisors neglected to do before the vote and, in turn, shows how harmful the decision is to vulnerable US toddlers.
The decision last fall followed clumsy discussion by Kennedy's dubiously qualified advisors, who make up the Advisory Committee on Immunization Practices (ACIP) for the Centers for Disease Control and Prevention. Most noticeably, their unprompted review of the MMRV vaccine did not include a standard decision-making framework ACIP has historically used to comprehensively evaluate what the change would mean for US children in practice—including basic questions, such as which children would be affected.
Still, the decision meant that private health insurance providers would no longer be required to cover the vaccine, called MMRV. It also meant the shot would no longer be available through a federal program that provides vaccines to about half of American children, mostly from low-income families.
