HLA-A and influenza: Moreover, we show that this strategy can be applied to epitopes specific for other alleles by improving binding of influenza epitopes ILRGSVAHK (NP265-273), SFSFGGFTK (PB2322-330) and RMVLSAFDER (NP67-76) (in order of decreasing dominance) to HLA-A*0301, another frequently occurring allele in the Caucasian population [34].
