To stop the spread of tuberculosis, scientists are working to develop methods that prevent new infections and also eliminate infection in the huge reservoir of people who already are infected with MTB. New approaches that focus on controlling or stimulating the immune system to cure latent infections or prevent MTB from causing disease have the potential to significantly reduce illness, death, and disease transmission. Dr. Andersen's is leading a collaborative team of international researchers who are studying Mycobacterium tuberculosis to identify the mechanisms that, in some people, allow it to escape natural immune system responses. The project's ultimate goal is to develop vaccines that target latent TB, either before or after an individual is infected.
