Tuberculosis
What is it?
Tuberculosis is a serious (sometimes life-threatening) infection of the lungs by a bacterium called Mycobacterium tuberculosis. Tuberculosis can also affect other organs in addition to the lungs.
​
The tuberculosis vaccine is called BCG, which stands for bacille Calmette-Guerin. The vaccine contains live, attenuated Mycobacterium bovis, which is a relative of Mycobacterium tuberculosis.
This vaccine is not routinely recommended in the US because tuberculosis is uncommon, and the vaccine has variable efficacy against tuberculosis in adults. In addition, BCG vaccination can cause a positive result on a tuberculin skin test (a test for tuberculosis infection). However, it is widely used in places where tuberculosis is common.
​
The BCG vaccine is also used to treat bladder cancer.
