What is tuberculosis?

Tuberculosis, also called TB, is a serious respiratory ailment caused by the spread of mycobacterium tuberculosis. It's an airborne disease and causes a variety of serious symptoms, including coughing (sometimes producing blood), chest pains, weakness, weight loss and fever. The current vaccine for the disease is called Bacille Calmette Guerin (BCG). Today, more than 1 billion people have received the vaccine, which generally protects against the disease for 15 years.

Who gets it?

BCG is often given to infants living in high-risk areas (including those living in extreme poverty and in the developing world).

What are the side effects?

BCG is one of the world's most commonly used vaccines. The main adverse reaction includes swelling and scarring at the injection site.

Vaccine recommendations

Several health organizations including the World Health Organization recommends the vaccine for infants in high-risk areas.

What you need to know

The vaccine also is used to treat bladder tumors and bladder cancer. After you've received the vaccine, you should keep the injection site dry for at least 24 hours to avoid infection.
