T-cell responses induced by the adjuvanted H7N9 WV vaccine. BALB/c mice (n = 4 per group) were intramuscularly immunized twice with the H7N9 WV vaccine in combination with aluminum hydroxide (Alum) or CpG 1018. Splenocytes were collected at day 7 after the second immunization, and the levels of secreted IFN-γ, IL-2, IL-5 and IL-13 (a–d) were evaluated after restimulation with recombinant H7 protein. (e, f) The ratios of IFN-γ to IL-5 and IFN-γ to IL-13 were calculated. The log10-transformed cytokine level and IFN-γ/IL-5 and IFN-γ/IL-13 ratios were analyzed by two-way ANOVA with Tukey’s posttest. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
