Frequencies of SARS-CoV-2-specific activation-induced markers (AIM)+ CD4+ or CD8+ T cells according to the severity of illness. (A) Frequencies of SARS-CoV-2-specific AIM+ (OX40+CD137+) CD4+ T cells according to the severity of illness. (B) Frequencies of SARS-CoV-2-specific AIM+ (CD69+CD137+) CD8+ T cells according to the severity of illness. Statistical analyses were 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).
