New TB vaccine candidate MTBVAC enters Mid-Stage human trial
NCT ID NCT06997367
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
