Memory B-cell responses against SARS-CoV-2 according to the severity of illness. (A, C, E) Representative gating strategy for IgM+, IgA+, and IgG+ antigen-specific memory (CD27+ CD19+) B cells. (B, D, F) Frequencies of IgM+, IgA+, and IgG+ antigen-specific memory B cells according to the severity of illness and different antigens. Statistical analysis was performed using the Kruskal–Wallis rank-sum test with Dunn’s post hoc test in GraphPad Prism (n.s.: P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001).
