Age limit wasn’t part of advisory committee’s vote on third shot of the COVID vaccine, but aligns with concerns about myocarditis in younger recipients.

J&J announced strong data for its single-shot vaccine, with even stronger booster shot data to boot. Also Gilead posted strong results for outpatient use of Veklury, but it faces stiff competition, while Clover announced new data and Pfizer/BioNTech sold another 500 million vaccine doses for donation.

Pressure is growing on richer countries to share their excess vaccine doses, and the European Parliament has passed legislation intended to strengthen the EU’s health security framework and make joint vaccine procurement more transparent.

ACIP will get a chance to further restrict and tailor the US booster plan for COVID vaccinations. Among other things, CDC's advisors may have to define what constitutes being at high risk of severe COVID-19 post-primary vaccination, occupations at high risk of COVID exposure, and whether people who didn’t receive Pfizer’s primary vaccine series could get the company’s mRNA booster shot.
