Summary

This phase II trial tests a new tuberculosis vaccine called MTBVAC (BBV169) in 164 healthy adolescents and adults. Some participants get the new vaccine, others get the standard BCG vaccine. The study checks how safe the vaccine is and how well it triggers an immune response, aiming to find a better TB vaccine.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MTBVAC (BBV169) vaccine
What this could lead to
If successful, this could lead to a more effective tuberculosis vaccine than the current BCG, potentially reducing TB cases worldwide.
What could go wrong
This is a mid-stage trial with only 164 participants, so results may not apply broadly. The vaccine is still experimental and may not prove safer or more effective than BCG.
