The FDA said Tuesday annual COVID shots will still be regularly approved for seniors and younger people with increased health risks from the virus.

Annual COVID-19 shots for healthy younger adults and children will no longer be routinely approved under a major new policy shift unveiled Tuesday by the Trump administration.

Top officials for the Food and Drug Administration laid out new requirements for yearly updates to COVID shots, saying they’d continue to use a streamlined approach that would make vaccines available to adults 65 and older as well as children and younger adults with at least one health problem that puts them at higher risk.

But the FDA framework urges companies conduct large, lengthy studies before tweaked vaccines can be approved for healthier people. In a framework published Tuesday in the New England Journal of Medicine, agency officials said the approach still could keep annual vaccinations available for between 100 million and 200 million adults.
