New study offers promising approach to TB vaccine testing

Tuberculosis (TB) remains a major global health threat, with more deaths than any other infectious disease. A new study in the Journal of Infectious Diseases presents a promising approach to accelerate TB vaccine testing. Researchers used the Bacillus Calmette-Guérin (BCG) vaccine to gather data on TB in a human study without exposing participants to full-strength TB bacteria. The findings could lead to more efficient TB vaccine development and a better understanding of TB immunity.
