The emergence of the novel reassortant A(H1N1)-2009 influenza virus highlighted the threat to the global population posed by an influenza pandemic. Pre-existing CD8(+) T-cell immunity targeting conserved epitopes provides immune protection against newly emerging strains of influenza virus, when minimal antibody immunity exists. However, the occurrence of mutations within T-cell antigenic peptides that enable the virus to evade T-cell recognition constitutes a substantial issue for virus control and vaccine design. Recent evidence suggests that it might be feasible to elicit CD8(+) T-cell memory pools to common virus mutants by pre-emptive vaccination. However, there is a need for a greater u..
