There is a vaccine to prevent TB called Bacille Calmette-Guerin (BCG). BCG is mainly used to protect babies and young children against TB if they are living in an area with a lot of TB.
In Canada, very few people get the BCG vaccine. Babies in First Nations and Inuit communities with high rates of TB are the only ones who routinely get the BCG vaccine.
