bcg vaccine

“BCG” is short for Bacillus Calmette–Guérin, and is the name given to a vaccine that is primarily used against tuberculosis. Basically, BCG-vaccine stimulates the body's immune response to the bacteria, without actually causing the disease. It is worth noting that this vaccine should be used with caution in people with eczema (that is, skin at injection site should be free from eczema). However, it should not to be given to people who have ever had tuberculosis, or to new-born babies in a household where an active TB case is suspected or confirmed. In addition, people with malignant conditions such as leukemia and lymphoma should never use this vaccine as well. As for the vaccine’s side effects, they are actually rare, save for redness, swelling, and mild pain at the site of injection. Plus, a small ulcer may also form with some scarring after healing.
