Clinical outcome and lung index following influenza A/H1N1 virus infection. (A) Survival rate of mice after infection with influenza A/H1N1 virus, which was significantly higher after day 6 for the rL H5-primed mice. n = 12/group. (B) The lung index of mice after infection with influenza A/H1N1 virus (*, as compare with group 4 [PBS-H1N1], P < 0.05). n = 3/group. (C) Lung viral loads on day 5 p.i. with influenza A/H1N1 virus (a, as compare with group 1 [rL H5-H1N1], P < 0.05; b, as compare with group 3 [H1N1- H1N1], P < 0.05; c, as compare with group 4 [PBS-H1N1], P < 0.05). n = 3/group.
