New Covid vaccines from Pfizer, Moderna and Novavax will likely provide protection against the new “Eris” variant, now the dominant strain of the virus in the U.S.
The drugmakers designed their updated vaccines to target the omicron subvariant XBB.1.5, which is slowly declining nationwide. But health experts and initial data suggest that the new shots will still be effective against Eris, or EG.5, and other widely circulating variants – all of which are descendants of omicron.
