Extended Data Fig. 5: Plasma IFN-γ and IL-2 concentration in relation to SARS-CoV-2 serostatus and age quartile.

a) IFN-γ concentration from SARS-CoV-2 seropositive (red, n = 92) and seronegative (black, n = 72) donors. Tukey’s multiple comparations test no significance seen. b) IL-2 concentration from SARS-CoV-2 seropositive (red, n = 92) and seronegative (black, n = 72) Tukey’s multiple comparations test * p = 0.02 **p = 0.005.
