Figure 2From: Intramuscular immunization of mice with live influenza virus is more immunogenic and offers greater protection than immunization with inactivated virusKinetics of cytokines present in serum and BAL following primary immunization with live or inactivated A/WI/05 delivered IM or live virus delivered IN. Mice were immunized and cytokines measured in sera of individual mice using multiplex MSD analysis. Mean IL-1β, IL-12, and IFN-γ concentrations for each group (n = 3) are shown before (day 0) and after immunization.Back to article page
