CD79A and COVID-19: In addition, there were few to no correlations observed between endemic CoV binding antibodies (markers 15-26) and SARS-CoV-2-specific functional antibody responses among participants who recovered from symptomatic outpatient COVID-19, except for IgA binding to OC43 RBD which weakly correlated with SARS-CoV-2-specific neutralization and ADCC and SARS-CoV-2-specific ADCP which moderately correlated with IgG1 binding to endemic 229E and OC43 RBDs in PLWH (Fig. 3b).
