Summary
Tuberculosis vaccine development is advancing, with over 100 candidates created. Promising vaccines are now entering human trials, offering hope against Mycobacterium tuberculosis.
Area of Science:
- Immunology
- Vaccinology
- Infectious Diseases
Background:
- Tuberculosis (TB) remains a global health crisis, causing millions of deaths annually despite widespread BCG vaccination.
- Over 100 TB vaccine candidates have been developed using diverse strategies to elicit protective immunity.
Purpose of the Study:
- To summarize the recent progress in tuberculosis vaccine development.
- To highlight the transition of promising TB vaccine candidates into human clinical trials.
Main Methods:
- Screening of TB vaccine candidates in small animal models against virulent Mycobacterium tuberculosis strains.
- Evaluation of vaccine efficacy in preclinical models to identify candidates for human trials.
Main Results:
- Significant resurgence in TB vaccine research over the last decade.
- Advancement of the most promising TB vaccine candidates into human safety trials.
Conclusions:
- The field of TB vaccine development is experiencing unprecedented progress after 80 years.
- Emerging TB vaccines show potential to combat the ongoing global burden of tuberculosis.
