Camel VHH Nanobodies Bind the S2 Subunit of SARS-CoV-2 and Broadly Neutralize Variants including Omicron
Since its emergence in 2019, COVID-19 infected over 600 million people and over 6 million people have died from the disease. COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. Neutralizing antibodies have been developed to bind to the receptor binding domain (RBD) on the spike (S) protein. Blocking the interaction of the RBD and the ACE2 receptor, is critical in neutralizing the virus. However, the S2 subunit, is also critical for viral infection and entry into human cells.
