In addition, we detected T cells specific for one HLA-A*02:01-restricted EBV epitope at both cycles (BRFL-1, 0.039 and 0.037% of CD8+ T cells, respectively) and for one HLA-A*03:01-restricted influenza epitope at cycle 1 day 1 (NP, 0.018% of CD8+ T cells) in the same patient (Fig. 2b and see also Additional file 8: Table S5). Here, CD8A is linked to influenza.
