Inactivated influenza vaccination reduced IL‐4 and IL‐6 in the BALF of allergic asthma mice. Mice were immunized with OVA/Alum, inoculated with inactivated PR8 influenza virus or PBS, and challenged with intranasally OVA. Mice were euthanized on day 44 as shown in Figure 3A. BALF cytokines (A) IL‐4, (B) IL‐5, (C) IL‐6, (D) eotaxin, and (E) IFN‐γwere determined by ELISA. N = 9 mice per group. **P < 0·01; ***P < 0·005.
