The Omicron variant of the Covid-19 virus could lead to more infections among vaccinated people, according to several scientists, but some said there were reasons to believe the shots would protect against severe disease.
While the new variant might evade the antibodies generated in reaction to the vaccines, the virus will likely remain vulnerable to immune cells that destroy it once it enters the body, said Ugur Sahin, co-founder of BioNTech SE, which sells a Covid-19 shot with partner Pfizer Inc.
