T-cell responses to common coronaviruses in patients with cMCAD (n = 17), and patients without cMCAD with a history of mild to moderate COVID-19 (n = 17) or severe COVID-19 (n = 15), or healthy donors (n = 15). Identification of HCoV-OC43–, HCoV-229E–, HCoV-HKU1–, and HCoV-NL63–specific T-cell responses, using ELISpot assays. Results were expressed as SFCs/10⁶ CD3⁺ T cells after subtraction of background values from wells containing nonstimulated cells. cMCADs, Patients with cMCADs, convalescing from mild to moderate (m-m) or severe COVID-19; ns, nonsignificant
