Moderna says its experimental COVID-19 vaccine that combines its original shot with protection against the omicron variant appears to work. COVID-19 vaccine makers are studying updated boosters that might be offered in the fall. Moderna says its combination booster candidate increased omicron-fighting antibodies more than just giving another dose of the original. Today’s vaccines still offer strong protection against COVID-19 hospitalization and death but protection against milder infections wanes especially as the virus continues to mutate. Health authorities are considering whether to order a change in the vaccine recipe. Moderna announced its preliminary study results Wednesday.
