What is the BCG (Tuberculosis) vaccine?
Tuberculosis (TB) is a serious bacterial infection that primarily affects the lungs, but it can also impact other parts of the body such as the lymph nodes, bones, and brain. TB is spread through the air when an infected person coughs or sneezes. While it can be treated with antibiotics, prevention through vaccination is key to controlling its spread.
The BCG vaccine (Bacillus Calmette-Guérin) is one of the oldest vaccines still in use and is particularly effective in preventing severe TB in children, such as TB meningitis and miliary TB (a widespread form of the disease).
