SARS-CoV-2 T cell responses and correlations with antibody responses among early pandemic convalescent COVID-19 inpatients and prepandemic controls. (A) IFN-γ ELISPOT responses to selected structural and accessory SARS-CoV-2 antigens. (B and C) Spearman correlations between aggregate IFN-γ ELISPOT responses and RBD and NTD binding (B) and pseudovirus Nab responses (C). Bars represent geometric means. Dotted lines represent LOD. Convalescent COVID-19 inpatient and prepandemic and subjects were compared by Mann-Whitney test. *, P < 0.05; **, P < 0.01.
