TB vaccine research

TB vaccine research aims to develop more effective and longer-lasting vaccines to prevent tuberculosis, a bacterial infection primarily affecting the lungs. Scientists explore new approaches, including novel vaccine formulas and delivery methods, to improve immune responses and overcome limitations of the existing Bacillus Calmette-Guérin (BCG) vaccine. These efforts involve understanding how the immune system fights TB, testing candidate vaccines in labs and clinical trials, and ensuring safety and efficacy. The goal is to reduce TB cases worldwide, especially in regions with high disease burden, ultimately contributing to better global health outcomes.
