Vaccination to prevent TB

Vaccine which is used against TB infection is BCG. The BCG vaccine contains a live but weakened form of Mycobacterium bovis, which is one of the bacterium that causes tuberculosis (see previous posts). The vaccine is known as BCG vaccine because a strain of bacterium known as Bacillus Calmette-Guerin is used in this process. The vaccine is used to prevent tuberculosis and works by stimulating the body’s immune response to the bacteria without actually causing the disease.
