Frequency of RSV-specific IFNγ and IL-4 secreting cells after virus challenge.

<p>The number of G₁₈₃-specific (grey bars) and M2₈₂-specific (black bars) IL-4 (A) or IFNγ (B) producing splenocytes was determined by ELISPOT in cells harvested 5 days post-challenge. The data are presented as cytokine spots/10⁶ splenocytes. Error bars represent the SEM from n=5 mice per group. *, #, p<0.05, significant difference as determined by one-way ANOVA and Dunnett’s test, compared with PBS vaccinated control mice (*) or compared to live RSV A2 vaccinated mice (#).
