A panel of advisers to the U.S. Centers for Disease Control and Prevention (CDC) on Thursday are considering several recommendations for rollout of COVID-19 vaccine boosters from Moderna Inc and Johnson & Johnson , expected to pave the way for additional shots for millions of Americans.

The U.S. Food and Drug Administration on Wednesday authorized the booster doses U.S. FDA clears Moderna, J&J COVID-19 boosters, backs use of different vaccine for boost, and said Americans can choose a different shot from their original inoculation.

The CDC is expected to sign off in the coming days on the recommendations of the panel for a rollout that health officials said could be confusing.
