SCIB-3

There are four populations in Recombinant Mycobacterium tuberculosis Vaccine Freeze-dried (AEC/BC02) phase I clinical research. The clinical study adopt open research design.
Population I have 25 subjects who received Tuberculin purified protein derivative(TB-PPD) skin test and specific gamma-interferon (γ-IFN)detection whose results are both negative ;Population II have 30 subjects who received Tuberculin purified protein derivative(TB-PPD) and ESAT6-CFP10 skin test in different arms , specific gamma-interferon (γ-IFN) detection whose results are all negative.We call polulation III as uninfected TB PPD positve population.This group screened 30 subjects whose ESAT6-CFP10 skin test and specific gamma-interferon (γ-IFN)detection results are both negative,but Tuberculin purified protein derivative(TB-PPD) skin test positive.50 subjects whose three kinds of detection results are all positive γ-IFN,TB-PPD and ESAT6-CFP10 ) are named as population IV.
After filtrating, injecting of population I start firstly.After ensure the safety of the population I,the population II～polulation IV carry out in turn the implementation at the same time.
