Definition

A neutralizing human monoclonal antibody directed against the spike (S) protein of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), that can potentially be used for passive immunization against Coronavirus disease 2019 (COVID-19). Upon administration, sotrovimab specifically targets and binds to an epitope on the SARS-CoV-2 S protein that is shared with SARS-CoV-1, thereby blocking viral attachment and entry into human cells and may thereby neutralize SARS-CoV-2. This may slow the progression of the disease and accelerate recovery, and may potentially provide temporary protection against infection with SARS-CoV-2. S protein, usually found on the surface of SARS-CoV-2, plays an essential role in the infection pathway of the SARS-CoV-2 virus.
