claim: neutralising antibodies drive fc mediated sars-cov-2 evasion
evidence_1: in vitro , the spike escape variant conferred decreased sensitivity to multiple units of convalescent plasma/sera from different recovered patients, whilst maintaining infectivity similar to wild type.", "these data reveal strong positive selection on sars-cov-2 during convalescent plasma therapy and identify the combination of spike mutations d796h and δ h69/ δ v70 as a broad antibody resistance mechanism against commonly occurring antibody responses to sars-cov-2.")
