Moderna says its experimental COVID-19 vaccine that combines its original shot with protection against the omicron variant appears to work.
FILE - In this Dec. 15, 2020, file photo, a sign for Moderna, Inc. hangs on its headquarters in Cambridge, Mass. Moderna's experimental COVID-19 vaccine that combines its original shot with protection against the omicron variant appears to work, the company announced Wednesday, June 8, 2022. COVID-19 vaccine makers are studying updated boosters that might be offered in the fall to better protect people against future coronavirus surges.
Moderna's preliminary study results show people given the combination shot experienced a higher boost in omicron-fighting antibodies than if they just got a fourth dose of the original vaccine. So U.S. regulators, and the World Health Organization, are considering whether to order a change in the vaccine recipe for a new round of booster shots in the fall -- when cold weather and kids returning to school are expected to drive yet another surge.
