Figure 2. Ex vivo recognition of the HA and NA of the H3N2 and H5N1 influenza A strains by healthy Vietnamese individuals.
Shown are the magnitudes of ex vivo ELISpot IFN-γ responses to the overlapping peptide pools representing HA (black) and NA (gray) of the H3N2 (A) or H5N1 (B) strains from H5-seronegative healthy Vietnamese participants (n = 20). These participants are shown on the x axis in the same order for A and B.
