Lung cytokine expression. Expression of mRNA for the cytokines IL-6 and IFN-γ in the lungs of RSV-infected litters born to naive (black symbols) or RSV-primed (red symbols) dams vaccinated as indicated (n = 3–10). Control (C) represents animals that were naive and not infected (used as baseline for mRNA expression). Symbols represent the mean of individual litters. Bar across represent the mean ± s.e.m. of a group. Boxes represent the boundaries of the quartiles. Comparison of the expression between the respective mock-vaccinated group and VLPs or RSV-i.m.-vaccinated groups was assessed by one-way ANOVA followed by Tukey post hoc test. +p < 0.0001; **p < 0.005; *p < 0.05
