When exposed to vaccines against influenza (respectively, subunit, immunoadjuvant, and split-), IL-17A, IL-9, IL-22 levels increased compared to the control (PBML supernatant without vaccines): IL-17A levels were 3.6, 3.5, and 3.8 times higher compared to the control (from 53.8 to 197, 192.6, and 208.9 pg/mL, SD = 22.8, 17.1, 32.8, p < 0.001; Figure 3). The gene discussed is IL22; the disease is influenza.
