> Sotrovimab, the newest antibody therapy, was developed by GlaxoSmithKline and Vir Biotechnology after a large collaborative study by scientists from across the nation discovered a natural antibody (in the blood of a SARS survivor, back in 2003) that has remarkable breadth and efficacy. > Experiments showed that this antibody, called S309, neutralizes all known SARS-CoV-2 strains – including newly emerged mutants that can now “escape” from previous antibody therapies – as well as the closely related original SARS-CoV virus.
