Indeed, CCL2 [Figure 2G, two-way ANOVA Finfection(1, 9) = 37.05, p = 0.0002], IFNγ [Figure 2H, two-way ANOVA Finfection(1, 9) = 8.03, p = 0.01], and IL1β [Figure 2I, two-way ANOVA Finfection(1, 9) = 5.21, p = 0.04] levels were increased after H7N7 infection, and even this increase was statistically significant in the case of CCL2 (p = 0.03) in the vaccinated group compared with unvaccinated mice. Here, CCL2 is linked to infection.
