UPDATE 1-U.S. FDA to allow mixing and matching of COVID-19 boosters- NYT

(Adds background, details from NYT report)

Oct 18 (Reuters) - The U.S. Food and Drug Administration is planning to allow Americans to get a different booster shot of a COVID-19 vaccine than the one initially taken, the New York Times reported on Monday.

The FDA in September authorized a booster dose of Pfizer Inc and partner BioNTech's two-shot COVID-19 vaccine for those aged 65 and older and some high-risk Americans.

The regulator's advisory panel has also backed the use of Moderna Inc and Johnson & Johnson's COVID-19 vaccine booster shots.

The government would not recommend one shot over another, and it might note that using the same vaccine as a booster when possible is preferable, the NYT report https://nyti.ms/3vmBRYE said, citing people familiar with the agency's plans.

The FDA declined to comment on the matter.

U.S. health officials have been under pressure to authorize the additional shots after the White House announced plans in August for a widespread booster campaign pending approvals from the FDA and the U.S. Centers for Disease Control and Prevention.

A study by the National Institutes of Health last week showed people who got Johnson & Johnson's COVID-19 vaccine as a first shot had a stronger immune response when boosted with vaccines from Pfizer and Moderna. (Reporting by Amruta Khandekar; Editing by Maju Samuel)
