What happened

Story audio is generated using AI For more than a century, the Bacille Calmette-Guérin vaccine given to babies shortly after birth has been the world’s only licensed vaccine against tuberculosis.

Why it matters

Now, scientists are testing what could become the first new TB vaccine in more than 100 years, with Phase 3 clinical trials under way in SA and several other countries.

Common ground

For a country among those with the highest TB burden globally, the vaccine could mark a major breakthrough if proved safe and effective, according to Gaurang Tanna, senior TB programme officer at the Gates Foundation.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
