Fig. 3: Breadth of T-cell response measured by ELISpot.

Graphs represent the total spike-specific IFNγ response (sum of peptide pools) measured in outbred CD1 (n = 8) (A) or inbred BALB/c (n = 6) (B) 3 weeks after the final vaccination. Pie charts represent the response to each peptide pool as a proportion of total response. Data points represent individual mice and bars represent the median response in each group. Data in each graph were analysed with a two-way ANOVA Friedman test and post hoc Dunn’s multiple comparison to compare between vaccination regimens, p-values indicate significant difference (p < 0.05) between groups.
