Moderna says updated COVID vaccine is effective against newer variant

Moderna said clinical trial data showed its updated COVID-19 vaccine will likely be effective against the highly-mutated BA.2.86 subvariant of the coronavirus that has raised fears of a resurgence of infections. The company said its shot generated an 8.7-fold increase in neutralizing antibodies in humans against BA.2.86, which is being tracked by the World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC).
