As is reported by the World Health Organization （WHO）, each year the seasonal influenza viruses, i.e., human influenza A （H1N1）, A （H3N2） and B viruses, infected 5%- 15% of the world＇s population, leading to about 3 to 5 million cases of severe illness and about 250000 to 500000 deaths worldwide （WHO, 2014）. Vaccination is currently the most effective way to fight against it. Due to the frequent mutations on the HA protein, the virus often changes its antigen, which may lead to the ineffectiveness of the influenza vaccines （Carrat and Flahault, 2007; Taubenberger and Kash, 2010）.展开更多
