Key data on US J&J, Moderna COVID-19 boosters 'weeks away,' Fauci says

WASHINGTON - Data needed to determine the advisability of booster shots of the Moderna Inc and Johnson & Johnson COVID-19 vaccines is just weeks away, President Joe Biden's chief medical adviser said on Sunday, as officials signaled they expected boosters would be recommended for a broad swath of Americans.

U.S. health regulators already have begun to consider a third dose of the Pfizer/BioNTech vaccine. A U.S. Food and Drug Administration advisory panel on Friday recommended a third shot of the two-dose Pfizer/BioNTech vaccine for people age 65 and older or at high risk of severe COVID-19, but declined to endorse boosters for the wider population.

People who have received the two-dose Moderna vaccine or one-dose J&J vaccine are still awaiting guidance on possible booster shots.
