There was no significant difference in the frequency of A2/S269+CD8+ T cells between acute and convalescent COVID-19 donors, while minimal A2/S269+CD8+ and A2/Orf1ab3183+CD8+ T cells were detected in either unenriched or flow-through samples (SI Appendix, Fig. S2). The gene discussed is CD8A; the disease is COVID-19.
