J&J Vaccine Booster Shot

October 18, 2021

I think this frankly was always a two-dose vaccine … It would be hard to recommend this as a single-dose vaccine at this point.

FDA advisor Dr. Paul Offit on the FDA’s recommendation for Johnson & Johnson COVID-19 vaccine booster shots.
  • On Friday, an FDA advisory committee unanimously voted to recommend booster shots for Johnson & Johnson’s single-shot COVID-19 vaccine, following the company’s request for approval earlier this month.
  • CNBC reported J&J submitted data showing a second dose of their vaccine boosts “protection against symptomatic infection from 72% to 94% when administered two months after the first dose in the United States.”
  • Before the panel voted on the J&J booster shot, some committee members questioned whether they should postpone their decision due to concerns about limited data. The committee chair said of J&J vaccine recipients: “There is a public health imperative here because what we’re seeing is this is a group with overall lower efficacy than we have seen with the mRNA vaccines so there is some urgency to do something.” (The J&J vaccine does not use the mRNA technology that Pfizer and Moderna vaccines use to fight the virus that causes COVID-19.)
  • The FDA panel recommended booster shots for those ages 18 and up who have received the J&J vaccine at least two months prior.
  • The FDA generally follows the advice of the recommending committee, and a final decision is expected very soon. These are all important steps before the United States can begin administering booster shots of J&J’s COVID-19 vaccines.

Why It Matters: Over time, data has shown waning immunity following initial COVID-19 vaccinations. Pfizer’s vaccine booster shot was recently authorized, and last week the FDA advisory committee recommended Moderna’s vaccine booster shot – both for those older/at higher risk. More than 15 million Americans over the age of 18 have already received J&J’s COVID-19 vaccine, and could be eligible for the booster shot if it is authorized by the FDA and recommended by the CDC.

FDA panel unanimously recommends J&J Covid booster shots to adults who already got the first dose (CNBC).
