HLA-A*24:02 allele, highly prevalent in Indigenous populations, is associated with influenza-induced mortality, although the basis for this association is unclear. Here, we define CD8(+) T-cell immune landscapes against influenza A (IAV) and B (IBV) viruses in HLA-A*24:02-expressing Indigenous and non-Indigenous individuals, human tissues, influenza-infected patients and HLA-A*24:02-transgenic mice. We identify immunodominant protective CD8(+) T-cell epitopes, one towards IAV and six towards IBV, with A24/PB2(550-558)-specific CD8(+) T cells being cross-reactive between IAV and IBV. Memory CD8(+) T cells towards these specificities are present in blood (CD27(+)CD45RA(-) phenotype) and tissues (CD103(+)CD69(+) phenotype) of healthy individuals, and effector CD27(-)CD45RA(-)PD-1(+)CD38(+)CD8(+) T cells in IAV/IBV patients. Our data show influenza-specific CD8(+) T-cell responses in Indigenous Australians, and advocate for T-cell-mediated vaccines that target and boost the breadth of IAV/IBV-specific CD8(+) T cells to protect high-risk HLA-A*24:02-expressing Indigenous and non-Indigenous populations from severe influenza disease.
