Moderna announces step toward updating COVID shots for fall

Moderna hopes to offer updated COVID-19 boosters in the fall that combine the original vaccine with protection against the latest variant. Now it’s reporting a hint that such an approach might work.

Before omicron struck, Moderna began testing a shot combining the original vaccine with protection against an earlier variant named beta.

The company says people given that test combo shot developed more antibodies capable of fighting newer variants, including omicron, than today’s regular booster.

Studies are underway to see if a combination shot that adds omicron-specific protection works better.
