The US Food and Drug Administration on Wednesday authorised booster doses of the Covid-19 vaccines from Moderna Inc and Johnson & Johnson, and said Americans can choose a different shot than their original inoculation as a booster.

The decision paves the way for millions more people in the United States to get the additional protection with the highly contagious Delta variant of the virus causing breakthrough infections among some who are fully vaccinated.

The agency previously authorised boosters of the Pfizer Inc Covid-19 vaccine developed with German partner BioNTech SE at least six months after the first round of shots to increase protection for people aged 65 and older, those at risk of severe disease and those who are exposed to the virus through their work.

Last week, an advisory panel to the FDA voted to recommend a third round of shots of the Moderna vaccine for the same groups. The panel also recommended a second shot of the J&J vaccine for all recipients of the one-dose inoculation at least two months after receiving their first.
