List of new FDA guidelines for COVID-19 vaccine approval and use

The Trump administration has introduced new guidelines that restrict routine COVID-19 vaccinations for healthy children and younger adults. Announced Tuesday in the New England Journal of Medicine by FDA Commissioner Dr. Marty Makary and vaccine chief Dr. Vinay Prasad, the policy marks a significant shift from earlier recommendations that encouraged annual shots for nearly everyone.

Under the new rules, COVID-19 vaccines will continue to be available to adults aged 65 and older and younger individuals with medical conditions that increase their risk of severe COVID-19. However, healthy children and adults outside these groups will face stricter approval requirements. Drugmakers must now conduct large, randomized controlled trials to prove that new vaccines effectively prevent severe illness, hospitalization, or death before receiving FDA approval for these populations.

Previously, vaccine updates were approved based mainly on their ability to trigger antibody responses, a faster process that allowed more frequent booster shots. Dr. Makary and Dr. Prasad argue this approach was too broad. They wrote, “We simply don’t know whether a healthy 52-year-old woman with a normal BMI who has had COVID-19 three times and received six previous doses will benefit from the seventh dose.” They called the U.S. “the most aggressive” among developed nations in recommending COVID boosters and questioned the utility of repeated doses for healthy individuals.

The new guidelines mean vaccine manufacturers like Pfizer and Moderna will need to conduct more comprehensive and lengthy studies for vaccines aimed at healthy people. While antibody tests might suffice for high-risk groups, they are no longer enough for the general population. This could limit vaccine access for millions of Americans, depending on risk status, insurance, and healthcare providers.

The policy comes ahead of the first meeting of the FDA’s vaccine advisory panel under the Trump administration. It follows recent FDA decisions, such as the limited approval of Novavax’s COVID vaccine after Trump appointees overruled broader access recommendations by FDA scientists.

Representative Marjorie Taylor Greene praised the new guidelines, saying, “No one should have ever been forced to take an unproven and experimental shot. It turned out deadly with miscarriages and myocarditis going through the roof after the COVID shot was forced upon the American people.” She thanked Health Secretary Robert F. Kennedy Jr. for “rightly updating the FDA’s guidance” and called for “health freedom again.”

Conversely, vaccine expert Dr. Paul Offit from the Children’s Hospital of Philadelphia warned about potential problems. “Is the pharmacist going to determine if you’re in a high-risk group? The only thing that can come of this will make vaccines less insurable and less available,” he said. Offit also noted that booster shots have been shown to reduce mild and moderate illness for several months, even in healthy people.

FDA guidelines for COVID-19 vaccine approval

Diana Atieh, an influencer with the Make America Healthy Again movement, criticized the FDA for continuing to promote vaccines for people with preexisting conditions. She said, “It’s very important for the FDA to show the risks with any medical procedure like vaccinations, and here they have not done that—which shows how little they care about informed consent for consumers.”

The FDA’s publication of these guidelines directly in a medical journal, rather than through the standard draft-and-comment process, has raised procedural concerns. Some experts say this method might violate federal rules. It also risks overshadowing the CDC’s role, whose advisory panel is expected to debate vaccine recommendations soon.

Makary and Prasad suggested that companies conduct six-month placebo-controlled studies in healthy populations before seeking approval for vaccines intended for those groups. This would focus on preventing severe disease and death rather than just immune response.

The new guidance could limit access to annual COVID-19 shots for an estimated 100 million to 200 million people in the U.S. High-risk individuals will still have access, but healthy children and adults may face restrictions until more data becomes available.

As public health officials rethink the approach to COVID vaccinations, the debate continues over how often healthy people need boosters. Will these new rules increase trust in vaccines or create new barriers? The coming months will show how this policy shift plays out.
