FDA Intends to Put its Most Serious Warning on Covid Vaccines, Sources Say

January 29, 2026

The FDA is planning to add a black box warning—the agency's most serious safety alert—to COVID-19 vaccines, according to sources familiar with the matter, though the plan has not been finalized. This initiative is being led by Dr. Vinay Prasad, the FDA's chief medical and scientific officer, who has been a vocal critic of COVID-19 vaccine policies and recently claimed that at least 10 children died because of the vaccines, though he provided no supporting data. Outside public health experts and former federal officials have strongly criticized the move, stating there is no scientific basis for such a warning and expressing concern that the decision appears politically motivated rather than based on transparent scientific review.

Who is affected

Children and adolescents, particularly males aged 12-24 who have the highest observed risk of myocarditis
Pregnant women (mentioned as potential targets of safety concerns)
The general public receiving COVID-19 vaccines
Vaccine manufacturers Pfizer and Moderna
Public health officials and agencies including the CDC and FDA
Former federal health officials expressing concern
Dr. Vinay Prasad (FDA's chief medical and scientific officer orchestrating the plan)
Robert F. Kennedy Jr. (HHS Secretary and vaccine skeptic)
Outside public health experts criticizing the decision

What action is being taken

The FDA intends to put a black box warning on COVID-19 vaccines
The plan is being orchestrated by Dr. Vinay Prasad
The FDA is looking into whether deaths "across multiple age groups" might be related to COVID-19 vaccines
HHS stated that "any questions regarding potential safety issues are being thoroughly reviewed by the FDA's established scientific and regulatory processes"
Children's Health Defense filed a citizen petition this week seeking to revoke licenses for the vaccines

Why it matters

This matters because black box warnings are the FDA's most serious safety alert, designed to warn about life-threatening risks, and such a warning could significantly undermine public confidence in COVID-19 vaccines that have been demonstrated to save millions of lives. The significance is heightened because the decision appears to lack the transparent scientific review process typically required for such warnings, with no public data release, advisory committee consultation, or notification to the public about the safety investigation. The move represents a dramatic reversal from the Trump administration's first-term achievement of Operation Warp Speed, which developed these vaccines, and could discourage vaccination uptake, potentially leading to preventable deaths. Public health experts are particularly concerned that the decision appears politically motivated rather than evidence-based, part of a broader pattern of messaging that contradicts established scientific evidence and could erode trust in all vaccines.

What's next

The warnings are expected to be unveiled by the end of the year, though the plan has not been finalized and may still change. It remains unclear whether the warnings would apply only to mRNA vaccines or all COVID-19 vaccines, and whether they would apply to all age groups.
