Figure 3From: Intramuscular immunization of mice with live influenza virus is more immunogenic and offers greater protection than immunization with inactivated virusKinetics of cytokines present in (A) serum and (B) BAL following secondary IM immunization with live or inactivated A/WI/05, or after a secondary dose of live virus delivered IN. The concentration of cytokine was measured in samples collected from individual mice using multiplex MSD analysis. Mean values of IFN-γ, IL-4 and IL-5 in sera and BAL of 3 mice per group are shown for each time point following the boosting dose.Back to article page
