claim: sequence mapping of viral mutations that escape antibodies used to treat covid-19
evidence_1: here we map how all mutations to sars-cov-2s receptor-binding domain (rbd) affect binding by the antibodies in regenerons regn-cov2 cocktail and eli lillys ly-cov016.", "finally, the maps reveal that mutations escaping each individual antibody are already present in circulating sars-cov-2 strains.")
