Answer:
Tuberculosis Shot
You are probably referring to tuberculosis vaccine called BCG vaccine. Bacillus calmette- Guerin is a vaccine against tuberculosis prepared from live attenuated tuberculous bacillus.
It is used to protect the person from tuberculosis. It has to be administered intradermally by a trained nurse who knows the technique of administration.
The vaccine is given intradermaly as a single shot in the arm, in the deltoid region of the arm.
Mild rash at the site of the injection is a local reaction which subsides after 2 to three days.
Some time abscess can develop, and use of antibiotics may be needed in such cases. The vaccine leaves a characteristic scar at the site of injection.
The other use of BCG vaccine is as its use in chemotherapy in the treatment of cancer of urinary bladder.
