Figure 4. Correlation of the T-cell responses against spike glycoprotein antigens of SARS-CoV-2 and HCoVs 229E and OC43 in study of intrafamilial exposure to SARS-CoV-2, France. Means of spot counts of interferon gamma–producing T cells per 1 million CD3+ cells in response to peptide pools spanning the N terminal (S1) and the C-terminal (S2) regions of spike glycoproteins of SARS-CoV-2 compared with HCoV-229E (A) and HCoV-OC43 (B) in 11 confirmed coronavirus disease cases (index patients), their seronegative partners (contacts), and 10 healthy blood donor controls. HCoV, human coronavirus; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
