Scientists test new method to speed up TB cure search

This study aimed to create a new research tool, called a 'challenge model,' to help scientists test future tuberculosis (TB) drugs and vaccines more quickly. Twenty healthy volunteers received a small, safe skin injection of the BCG vaccine (a weakened TB-related germ). Researchers then took tiny skin samples to measure how the body reacted and how standard TB antibiotics affected the injection site. The goal was to build a better testing method, not to treat or prevent TB in the participants.
