Here, the authors combine structural, binding, mutational in vitro and in vivo assays to characterize neutralizing antibodies derived from IGHV3-53/3-66 against SARS-CoV-2, finding one antibody, named P5A-3C8, to exhibit protective efficacy in a golden Syrian hamster model of infection while showing the emergence of mutations at position 417 of the Spike protein that confer resistance.
