RESUMO
Vaccination is important tuberculosis (TB) preventive strategy that is essential to achieve the goals of the End TB strategy. The BCG vaccination at birth offers protection against TB in young children but not in adolescents and adults. New TB vaccines are the need of the hour. The TB vaccine development pipeline in the past years is encouraging with newer TB vaccines in clinical trials in humans. The focus of the newer TB vaccine is the prevention of infection, disease, and recurrence of TB disease. Therapeutic vaccines focus on better treatment outcomes and prevention of TB recurrence. BCG revaccination is of current interest. Novel, safe, and efficient TB vaccines that prevent TB infection and disease if introduced in 2025 could drastically reduce the rate of TB incidence. However, the development of an effective vaccine for TB is challenging. Engagement of stakeholders, mobilizing funding, and advocacy could accelerate the newer TB vaccine development process.
