Immunogenicity and Protective Efficacy against Murine Tuberculosis of a Prime-Boost Regimen with BCG and a DNA Vaccine Expressing ESAT-6 and Ag85A Fusion Protein

Figure 4

Immunogenicity of r685A fusion protein in healthy population. A total of 17 household contacts with active TB patients were tested by TST and r685A-WBIA, respectively. Each square represents the IFN-γ concentration in a sample, and median values for TST− (n  =  7) and TST+ (n  =  10) groups are indicated by horizontal lines.
