Fully vaccinated people may still be at risk of infection from the California ‘Epsilon’ coronavirus variant, a new study finds.
Researchers from the University of Washington and Vir Biotechnology, based in San Francisco, found that the variant had three mutations on the spike protein, which the virus uses to enter and infect human cells.
These mutations could provide resistance to neutralizing antibodies generated by the Pfizer-BioNTech and Moderna vaccines.
