Marty Makary, who Trump nominated to lead the FDA and work with RFK Jr., opposed vaccine mandates during the pandemic.

RFK Jr. would also have the power, along with the FDA commissioner, to slow down or hamper the process by which new vaccines are evaluated, approved, and recommended. That could discourage pharmaceutical companies from developing new or reformulated vaccines.

The U.S. Food and Drug Administration’s (FDA) head of vaccine safety says that President-elect Donald Trump’s embrace of vaccine skeptics could be an opportunity for the science community to teach the public about the value of these life-saving drugs.
