Definition of BCG

BCG: An effective immunization against tuberculosis. BCG stands for Bacille Calmette Guerin. BCG is a weakened (attenuated) version of a bacteria called Mycobacterium bovis which is closely related to Mycobacterium tuberculosis, the agent responsible for tuberculosis.

Camille Guerin (1872-1961) and Albert Calmette (1863-1933) produced the BCG strain of the bacteria at the Pasteur Institute in Paris in 1921. Within a decade the BCG vaccine was being given in France and many other countries. By 1928, BCG had been given to 116,000 infants in France alone. However, conflicting questions about its effectiveness delayed the use of the BCG vaccine in the United States until 1950.

BCG is also used as an adjuvant to stimulate the immune response and in cancer chemotherapy.
