CD79A and viral infectious disease: Interestingly, humans share a high proportion of the same V(D)J-recombined antibody genes after contracting infectious diseases.49 Previous studies have reported several public antibody clonotypes in emerging virus infections.25,50 A recent research reported that IgA and IgG public antibody clonotypes shared between severe and mild COVID-19 individuals were identified.40 In this study, we identified paired heavy and light chains public antibody clonotypes shared by multiple convalescent COVID-19 patients.
