Human Response
- Vaccination Protocol: Participants received two subcutaneous injections of GamTBvac (0.5 mL each) administered eight weeks apart (Day 0 and Day 57) (Tkachuk et al., 2020).
- Immune Response: GamTBvac induced significant IFN-? release, increased Th1 cytokine-expressing CD4? T cells, and strong antigen-specific IgG antibody responses (Tkachuk et al., 2020).
