What is the full form of "BCG"?

Bacillus Calmette–Guerin (BCG) vaccine is a vaccine primarily used against tuberculosis (TB). It is named after its inventors Albert Calmette and Camille Guerin. In countries where TB or leprosy is common, one dose is recommended in healthy babies as soon after birth as possible. In areas where TB is not common, only children at high risk are typically immunized, while suspected cases of TB are individually tested for and treated.
