Shares of Novavax jumped more than 13% on Tuesday after the biotech company said its new Covid vaccine generated a broad immune response against the now-dominant Eris variant and another fast-spreading strain of the virus in small animal trials.
But the trial results suggest that the shot may still be effective against newer Covid variants gaining a greater foothold in the U.S. That includes Eris and XBB.1.16.6, both of which are also descendants of omicron.
"We have a lot of confidence in our updated Covid vaccine and are working diligently with global regulatory bodies to ensure our protein-based vaccine is available this fall," Filip Dubovsky, Novavax's president of research and development, said in a release.
The World Health Organization designated Eris a "variant of interest," meaning it will be monitored for mutations that could make it more severe.
XBB.1.16.6 is also beginning to surge, accounting for 8% of all cases nationwide as of Saturday, the CDC said.
