However, BCG is not generally recommended for use in the United States because of the low risk of infection with Mycobacterium tuberculosis, the variable effectiveness of the vaccine against adult pulmonary TB, and the vaccine's potential interference with tuberculin skin test reactivity.

Why did the TB vaccine leave a scar?

The BCG vaccine contains live attenuated Mycobacterium bovis and following intradermal injection the BCG vaccine elicits a local immune response. This response most often results in an ulcer that heals over weeks and leaves a flat permanent scar at the injection site [2].
