Figure 2. IFNγ (A) and IL-2 (B) ELISPOT responses during acute RSV infection and convalescence. Data were derived from 29 subjects with acute RSV disease. Results are reported as spot forming cells (SFC) per 10^6 PBMC. Bars represent median and interquartile ranges. N indicates the number of subjects who contributed data at each time point. P values were calculated using Wilcoxon matched signed-rank test and are shown only for significant differences (P < 0.05).
