A recently discovered virus in a Russian bat that is similar to SARS-CoV-2, the virus behind COVID-19, is likely capable of infecting humans and, if it were to spillover, is resistant to current vaccines. Researchers found spike proteins from the bat virus, named Khosta-2, can infect human cells and is resistant to both the monoclonal antibodies and serum from individuals vaccinated for SARS-CoV-2.
