Former leaders of the U.S. Food and Drug Administration have sharply criticized the agency's recent assertions questioning the safety of vaccines, calling proposed changes a threat to public health. These twelve former officials, spanning both Republican and Democratic appointments, voiced their concerns in an editorial published in the New England Journal of Medicine. They pointed to an internal memo from Dr. Vinay Prasad, the FDA's vaccine chief, which alluded to grave concerns regarding COVID-19 vaccinations and specified a shift in how vaccines for flu, COVID-19, and other respiratory illnesses should be managed.

The internal memo, which has not been made public, allegedly claimed without substantiation that COVID-19 vaccines were linked to ten deaths in children, which the ex-officials countered was based on a surveillance program lacking the necessary medical records to establish causation. They reinforced the fact that significant evidence supports the efficacy of COVID-19 vaccines in reducing severe disease and hospitalization among children.

The former FDA officials asserted that the proposed policy shifts not only deviate from established scientific evaluation frameworks but could also slow down the introduction of new vaccine formulations. They argue that the changes risk making the FDA's processes less transparent and more cumbersome, ultimately endangering those the agency is supposed to protect, particularly vulnerable populations.

The critique comes as Health Secretary Robert F. Kennedy Jr. seeks to redefine federal vaccine policies amid a backdrop of ongoing vaccine skepticism. Kennedy's recent actions have included restructuring advisory committees related to vaccine recommendations and administrative dismissals, which have raised further concerns about public health governance.

In conclusion, the former FDA leaders warned that embracing these changes could set a precedent that endangers long-held scientific principles regarding vaccine safety and public health.
