Dr. Paul Offit, a committee member, mentioned two doses are unlikely to supply safety towards mildness sickness from omicron’s subvariants, however they’d possible shield towards extreme sickness with a 3rd dose.

We’re not in the identical a part of this pandemic anymore. It is a totally different time.”
Nevertheless, Dr. Eric Rubin mentioned the FDA will at all times be evaluating vaccine effectiveness based mostly on earlier Covid variants given how shortly the virus evolves and the time it takes to collect knowledge.
