Comparing all influenza patients with healthy population (Supplementary Table S3), influenza patients presented a lower concentration of alpha and gamma interferons (IFN α: 1.3 vs 7.0 pg/mL p<0.001; IFNγ: 0.5 vs 4.8 pg/mL, p=0.002) and a higher concentration of IL-10 (10.8 vs 0.9 pg/mL, p<0.001) and IL-15 (2.3 vs 0.2 pg/mL, p<0.001). Here, IL15 is linked to influenza.
