In this study, recognition of 4 recombinant viral proteins (GST-NHA1) by the antibodies induced by multi-epitope vaccine was testified. Inhibitory activities of these antibodies were also investigated in vitro against four heterologous influenza A viruses (H3N2). Three epitope-specific antibodies purified by affinity chromatography could reduce the plaque formation. Interestingly, the three neutralizing antibodies in combination showed obvious enhancement of inhibitory activity, suggesting that the development of recombinant multi-epitope vaccine might be an effective way against viral mutation.
