The tuberculosis (TB) vaccine is rarely used in the United States. It is only recommended for children living with someone who is actively infected with TB who either (1) cannot take antibiotics to treat the infection or (2) is infected with a strain of TB that is highly resistant to all antibiotics. Decisions regarding this vaccine are typically made in consultation with a local TB control program. The TB vaccine is given as a single shot.
In most other countries, the vaccine for tuberculosis, known as the BCG vaccine, is used more commonly because of the frequency of tuberculosis.
