They identified 29 shared CD8+ T cell epitopes in COVID-19 convalescent patients across six HLA alleles: A*02:01, A*01:01, A*03:01, A*11:01, A*24:02, and B*07:02, with an affinity (equilibrium dissociation constant) of 2.8–206 nM as predicted by NetMHC4.0 [59,73,74]. This evidence concerns the gene CD8A and COVID-19.
