Is there a vaccine to prevent TB?

There is a vaccine for TB disease called Bacille Calmette-Guerin (BCG). It is used in some countries to prevent severe forms of TB in children. However, BCG is not generally recommended in the United States because it has limited effectiveness for preventing TB overall.

What should I do if I think I have been exposed to someone with TB disease?

If you think you have been exposed to someone with TB disease, you should contact your doctor or local health department about getting a TB skin test or special TB blood test. And tell the doctor or nurse when you spent time with this person.
