[The application of recombinant Bacillus Calmette-Guérin vaccine and its vector in infectious disease].

Recent studies show that the vector of recombinant Bacillus Calmette-Guérin (rBCG) has a series of advantages. With exogenous gene and vaccine in one inoculation, it can obtain strong and persistent immune response at one time so that BCG is considered as a kind of ideal vector for live recombinant vaccine. This review outlines the application of rBCG vaccine and its vector in infectious diseases caused by bacteria, viruses, other microorganisms and parasites.
