Cytokine gene expression of splenocytes from immunized mice. Mice (n=2) were immunized twice with the five vaccine formulations and isolated splenocytes from Day 28 were stimulated with purified antigens. Relative mRNA expression levels of various cytokines were determined, (A) pro-inflamatory cytokines (B) T helper cells. Data are presented as mean ± SEM and different superscript letters indicate significant differences (P < 0.05) between treatment groups
