Fig. 3From: Complete protection for mice conferred by a DNA vaccine based on the Japanese encephalitis virus P3 strain used to prepare the inactivated vaccine in ChinaSpecific humoral immune response and cytokine secretion produced by mice after immunization. In the third week after the mice were immunized three times with pV-JP3ME or pV, a IgG antibodies and b nAbs were produced with higher titers in the vaccine group than in the control group. One week after immunization, the mouse splenocytes produced high levels of c IL-2 and d IFN-γ upon JEV antigen stimulation. **P < 0.01, ***P < 0.001, n = 8 per groupBack to article page
