FDA panel votes to authorize booster shots for J&J vaccine
An independent FDA panel has voted to move forward with Johnson & Johnson vaccine boosters.
The panel’s decision on J&J was broader than for Moderna and Pfizer as it applies to all J&J recipients 18 and older. The timing is also different: The J&J booster can be administered two months after the initial shot.
The 19-person panel voted unanimously.
Johnson & Johnson's one dose has shown to be 85% effective against severe illness, but adding a second dose boosted that to 100%.
Penny Heaton, a J&J executive, acknowledged Friday that J&J’s efficacy is below the mRNA vaccines but said they would be on par if they used a booster.
