Study using humanized mice and blood samples from recovered COVID-19 patients to generate antibodies targeting multiple different regions of the critical receptor-binding domain (RBD) of the SARS-CoV-2 spike protein. The spike protein on the virus cell surface binds to the host cell and is required for infectivity. By blocking its interaction with the host cell, antibodies are able to neutralize the virus and block infection. Authors selected pairs of highly potent individual antibodies that simultaneously and non-competitively bind to the RBD. The multi-antibody approach is used to decrease the potential for the virus to escape.
