Global TB Caucus Library: New TB Vaccines

14 November 2025

New TB vaccines could change the course of the epidemic, saving millions of lives and reducing long-term costs. The current Bacille Calmette-Guérin (BCG) vaccine is over 100 years old and offers limited protection for adolescents and adults, who are most at risk.

​After decades of research, several new vaccine candidates are in final trials, with results expected in 2027 and 2028. Early preparation for roll-out will be key to ensuring access that is timely, equitable and affordable.

​Informed by an expert panel of scientists, policymakers and people with lived experience, a brief, released by the Global TB Caucus, outlines what good vaccine preparedness looks like and how parliamentarians can drive early action.
