IFN-γ (Th1) and IL-4 (Th2) cytokine levels in serum samples. (A) IFN-γ secretions of the immunized groups were significant higher than that of the control pVAX1 group (P < 0.01) but were not significantly different from each other (P > 0.05). (B) The IL-4 level of the multi-epitope vaccine group was significantly higher than the other 3 groups (P < 0.05). These data represent 3 repeated cytokine measurements.
