Researchers from the National Skin Centre (NSC) have developed a near-painless, micro-needle patch to shrink these blemishes, which are called keloid scars. The patch will offer patients an alternative to a monthly injection into the scar, which is currently the most effective form of treatment but is often painful.
What if scar is not seen after BCG vaccination?
While it is correct to ‘assume’ failed BCG vaccination if no scar is seen 90 days after inoculation, it does not necessarily mean that it had actually failed to induce some immune response that can be proved by laboratory tests.
Is BCG scar necessary?
The formation of the BCG vaccine scar is not necessary. It usually takes 3 to 6 months for the scar to form. If there is no scar, one needs to do Mantoux test. If negative, one should give repeat BCG.

BCG vaccine is not recommended after 12 months of age because the protection provided is variable and less certain. The recommended method of prevention for children who are younger than 12 months old is to immunize them as soon after birth as possible with BCG vaccine.
Why is TB vaccine not used in the US?
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.
