In this study, we examined the reactivity of human peripheral blood mononuclear cells to a panel of influenza A virus (IAV) CD8(+) T-cell epitopes that are recognised by the major human leukocyte antigen (HLA) groups represented in the human population. We examined the level of recognition in a sample of the human population and the potential coverage that could be achieved if these were incorporated into a T-cell epitope-based vaccine. We then designed a candidate influenza vaccine that incorporated three of the examined HLA-A2-restricted influenza epitopes into Pam2Cys-based lipopeptides. These lipopeptides do not require the addition of an adjuvant and can be delivered directly to the res..
