FDA Considering Black Box Warning for COVID Vaccines
Sunday, December 14, 2025
Strongest safety label would mark unprecedented shift in vaccine policy amid declining uptake
The FDA is reportedly preparing to add a black box warning—its strongest safety alert—to COVID-19 vaccines by year's end, according to multiple reports.
The potential warning, allegedly driven by FDA's chief medical officer Dr. Vinay Prasad, remains unconfirmed by HHS, which called reports "pure speculation." Health experts strongly oppose the move, emphasizing that COVID vaccines have been safely administered to billions worldwide and saved millions of lives. The development comes as vaccination rates plummet, with Massachusetts seeing only 10.4% uptake compared to 17.4% last year, and retail pharmacy vaccinations down 27% nationally since 2024.
