Moderna new vaccine

Moderna says updated vaccine works better against omicron variant…
Moderna on Wednesday said that a new version of its vaccine provided a superior immune response against the COVID-19 omicron variant, making it the lead candidate for a booster shot this fall.

The company released results on an updated, “bivalent” vaccine that includes both the original vaccine and an updated version specifically designed to target the omicron variant. That update allows the vaccine to provide better protection against that variant specifically, the company said.

A booster dose of the updated vaccine led to an eight-fold increase in neutralizing antibody levels, the company said.
