In recent months genomic characterization of pandemic SARS-CoV-2 isolates identified viral variants that are less susceptible to neutralization by convalescent plasma (CP), vaccine-elicited plasma/sera, or SARS-CoV-2 monoclonal antibodies than earlier SARS-CoV-2 strains. In this Viewpoint, Casadevall et al. argue against the causal association made in some press articles between the emergence of SARS-CoV-2 variants and convalescent plasma use.
