Summary of immunogenicity activities.

ELISpot was expressed as sfc/m; ICS as % CD4+ or CD8+ T cells; MFI as geometric mean; ELISA as titer or concentration; IFA as titer. p values were calculated by ANOVA over the course of this study and compare activities in Group 1 and Group 2 (@), CD4+ and CD8+ activities in each group (*), or MFI in CD8 triple cytokine secretors (CD8+3) and CD8+ single cytokine secretors (CD8+1) ($). CD8+M and CD4+M are multifunctional T cells (secreting two or more cytokines).
