What is BCG?
The BCG vaccine is made from a weakened strain of Mycobacterium bovis, a bacterium that causes tuberculosis in cattle. When administered to humans, the weakened bacterium triggers an immune response that protects against future infection with the active TB bacteria.
Mechanism of Action
The BCG vaccine works by stimulating the body's immune system to produce white blood cells called macrophages. These macrophages are able to recognize and destroy Mycobacterium tuberculosis bacteria, the causative agent of TB.
Effectiveness
The BCG vaccine is highly effective in preventing severe forms of TB, such as meningitis and miliary TB. It is estimated to be 50-80% effective in preventing pulmonary TB, the most common form of the disease.
Administration
The BCG vaccine is typically administered intradermally (just below the skin) to infants and children. It is usually given as a single dose, but in some cases, multiple doses may be required.
Safety
The BCG vaccine is generally safe, with minimal side effects. Common reactions include redness, swelling, and tenderness at the injection site. In rare cases, more severe reactions, such as fever and lymph node enlargement, can occur.
