Percentage of CD4+ and CD8+ T cells in the splenocytes of immunized mice. Mice (n=2) were immunized twice with the five vaccine formulations and isolated splenocytes were stained with anti-CD4+ and CD8+ antibody for flow cytometry analysis. Data are presented as mean ± SEM and different superscript letters indicate significant differences (P < 0.05) between treatment groups at the same time point for CD4+ and CD8+ T cells
