FDA panel debates lower-dose Moderna COVID shots for booster

Associated Press

U.S. health advisers are debating if millions of Americans who received Moderna vaccinations should get a booster shot -- this time, using half the original dose.

Already millions who got their initial Pfizer shots at least six months ago are getting a booster of that brand. Thursday, advisers to the Food and Drug Administration evaluated the evidence that Moderna boosters should be offered, too -- and on Friday, they’ll tackle the same question for those who got Johnson & Johnson’s vaccine.

U.S. officials stress that the priority is to get shots to the 66 million unvaccinated Americans who are eligible for immunization -- those most at risk as the extra-contagious delta variant of the coronavirus has burned across the country.

“It’s important to remember that the vaccines still provide strong protection against serious outcomes” such as hospitalization and death from COVID-19, said FDA vaccine chief Dr. Peter Marks.

But Marks said it’s also become clear there is some waning of protection against milder infections with all three of the coronavirus vaccines used in the U.S. And he encouraged the advisory panel to consider if the evidence backs similar booster recommendations for all of them as well, since that would “create the least confusion” for the public.
