Moderna says updated Covid-19 vaccine booster shows stronger antibody response against Omicron

Bivalent boosters address two viral strains in the same vaccine. The updated booster contains Moderna's original vaccine, and a vaccine candidate that targets the Omicron variant.
The vaccine was generally well-tolerated, the company said, with side effects similar to booster doses of the current vaccine.
The 50-microgram bivalent booster, called mRNA-1273.214, generated a stronger antibody response against Omicron than the original Moderna vaccine. Omicron subvariants are driving virtually all the new Covid-19 cases in the United States right now.

Moderna said it will seek authorization for an updated coronavirus vaccine designed to protect against omicron subvariants that the company described as its “lead candidate” for a fall booster, but it remains unclear how effective the shot will be against the latest versions of the omicron variant spreading in the United States.
