That double action suggested that the sotrovimab antibody attached itself to a part of the virus that has changed very little over the course of its evolution. Among all available monoclonal antibodies, bebtelovimab is the only one that has shown remarkably preserved in vitro activity against all SARS-CoV-2 variants, Vaccines still prevent severe disease from the Omicron variant because they prompt the body to develop antibodiesand more complicated systems, like white blood cellsfor a whole range of bricks.
