Moderna is likely to update the COVID-19 booster

Moderna hopes to offer updated COVID-19 boosters this fall, combining the original vaccine with protection against the latest variant.

Now it reports a hint that such an approach may work.

Currently, all COVID-19 vaccines are designed to tackle the original coronavirus strain.

But before omicron struck, Moderna began testing a shot that combined the original vaccine with protection against an earlier variant called beta.

The company says people who got that test combination shot developed more antibodies that were able to fight newer variants – including omicron – than today’s regular booster.

Researchers said the protection continued six months after the shot was given.

Studies are underway to see if a combination shot that adds omicron-specific and 31 other mutation protection works better.

Investigations into the two boosters are underway.

The results are expected in late June.
