👉 Apteroscelia, also known as the "Bacillus Calmette-Guerin" (BCG) vaccine, is a type of live attenuated vaccine that is given to infants and children to prevent certain types of bacterial infections. It works by stimulating the immune system in the body to produce antibodies against specific bacteria, which can help protect against infections such as pneumonia, meningitis, and upper respiratory tract infections.
