Sotrovimab retains activity against SARS-CoV-2 Omicron variant BQ.1.1 in a non-human primate model

The SARS-CoV2 Omicron variants have acquired new Spike mutations leading to escape from the most of the currently available monoclonal antibody treatments reducing the options for patients suffering from severe Covid-19. Recently, both in vitro and in vivo data have suggested that Sotrovimab could retain partial activity against recent omicron sub-lineage such as BA.5 variants, including BQ.1.1. Here we report full efficacy of Sotrovimab against BQ.1.1 viral replication as measure by RT-qPCR in a non-human primate challenge model. ### Competing Interest Statement The authors have declared no competing interest.
