BCG vaccine, vaccine against tuberculosis. The BCG vaccine is prepared from a weakened strain of Mycobacterium bovis, a bacteria closely related to M. tuberculosis, which causes the disease. The vaccine was developed over a period of 13 years, from 1908 to 1921, by French bacteriologists Albert Calmette and Camille Guérin, who named the product Bacillus Calmette-Guérin, or BCG. The vaccine is administered immediately after birth only in infants at high risk of tuberculosis. BCG vaccine produces an immune response that partly protects infants and young children from serious forms of tuberculosis.
