Recombinant intracellular pathogen vaccines and methods for use.

摘要

Vaccines and immunotherapeutics for preventing intracellular pathogen diseases in mammals are provided that consist of recombinant attenuated intracellular pathogens that have been transformed to express recombinant immunogenic antigens of the same or other intracellular pathogens. Exemplary vaccines and immunotherapeutics include attenuated recombinant Mycobacteria expressing the major extracellular non-fusion proteins of Mycobacteria and/or other intracellular pathogens. These exemplary vaccines are shown to produce surprisingly potent protective immune responses in mammals that surpass those of any previously known anti-mycobacterium vaccine. More specifically, a recombinant BCG expressing the 30 kDa major extracellular non-fusion protein of Mycobacterium tuberculosis is provided. Additionally, methods for preventing and treating diseases caused by intracellular pathogens are provided. The methods of treating and preventing intracellular pathogen diseases utilize the described surprisingly efficacious vaccines and immunotherapeutics.
