Several monoclonal antibodies against SARS-CoV-2 have been developed for the treatment of COVID-19 (Miguez-Rey et al., 2022). One of these is sotrovimab, which significantly reduced the risk of COVID-19 hospitalization and death due to infection with pre-Omicron SARS-CoV-2 variants in a randomized clinical trial (Gupta et al., 2021). The United States Food and Drug Administration (FDA) issued an emergency authorization to permit the use of sotrovimab for the treatment of mild-to-moderate COVID-19 in patients at high risk of progression to severe COVID-19 (US Food and Drug Administration, 2022).
