TB is a disease caused by bacteria that attack the lungs. The symptoms of TB are coughing, chest pain, fatigue, weight loss, and fever. The vaccine for TB is the Bacille Calmette-Guérin (BCG) vaccine. This vaccine is administered by injection and is given to people who are at high risk for TB.
The BCG vaccine is not 100?fective in preventing TB, but it is the best available prevention method. The vaccine works by protecting people from infection with the bacteria that cause TB. The BCG vaccine is given to people who are at high-risk for TB, such as healthcare workers and people who live in close quarters with someone who has TB.
