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.

The investigators concluded the vaccine was 60% (95% CI, 37-74) effective for less than 5 years, 56% (95% CI, 17-76) effective between 5 and less than 10 years, and 46% (95% CI, 18-64) effective for up to 15 years.

The BCG vaccine is given just under the skin. Two to four weeks later, a pustule occurs at the site. The pustule might open and drain. The size of the scar depends on the amount of inflammation caused by the person’s immune response and the person’s healing ability.
