Much is still unknown about the Omicron variant, including how resistant it may be to vaccines and whether people who become infected develop worse or milder COVID-19 symptoms. But its high number of mutations — and their location on the virus’s spike protein — suggests the new variant will be more easily transmitted than earlier versions of the virus, scientists say.
Dr. Anthony Fauci, President Biden's chief medical adviser, said Sunday that he was particularly concerned with the rate that the Omicron variant "exploded" in South Africa, adding to the evidence that the variant can spread quicker than others. "The profile of the mutations strongly suggests that it's going to have an advantage in transmissibility and that it might evade immune protection that you would get, for example, from a monoclonal antibody or from a convalescent serum after a person's been infected, and possibly even against some of the vaccine-induced antibodies.
