Protection efficacy against infection by H7N9 and H3N2 strains. The mice were challenged with lethal dose of virus in a volume 40 μl PBS through intranasal instillation. The body weight changes and survival rate were monitored daily for 14 days. The lung virus titers at day 4 post challenge were determined by standard plaque assays. Bars represent mean virus titers(Log10 pfu/ml) ± standard errors. a, d, lung virus titers. b, e, body weight changes. c, f, survival rate post challenge. *P < 0.05 were considered statistically significant: compared to G1 and G2 group
