Updated COVID boosters for Omicron BA.5 variant expected in September
CBSN
U.S. regulators said Friday they are no longer considering authorizing a second COVID-19 booster shot for all adults under 50 this summer, focusing instead on revamped vaccines for the fall that will target the newest viral subvariants.
Pfizer and Moderna expect to have updated versions of their shots available as early as September, the Food and Drug Administration said in a statement. That would set the stage for a fall booster campaign to strengthen protection against the latest versions of Omicron.
The announcement means the U.S. won't pursue a summer round of boosters using the current vaccines for adults under 50, as some Biden administration officials and outside experts previously suggested. They had argued that another round of shots now could help head off rising cases and hospitalizations caused by the highly transmissible Omicron strains.
