Of 30 individuals with long COVID assessed longitudinally using our personalized tetramer panel, four individuals had very high frequencies of SARS-CoV-2-specific CD8+ T cells, over 1000 tetramer+ cells per million CD8+ T cells (>10−3 frequency), early post infection (acute and 3 mo), which was generally attributed to one dominant epitope (A1/ORF1a1637N = 2, B40/N322N = 2) rather than the sum of multiple T cell specificities (Fig. 2D). The gene discussed is CD8A; the disease is infection.
