Investigating how long the BCG vaccine protects against tuberculosis infection

Durability of systemic and lung immune correlates of BCG-induced protection against M. tuberculosis infection

NIH-funded research University of Cape Town · NIH-10676971

This study is looking at how well the BCG vaccine protects against tuberculosis over time, especially in teenagers who are more likely to get the disease, by checking their blood and lung samples to find out how their immune system responds.

What this research studies

This research focuses on understanding the long-term immune responses generated by the BCG vaccine, which is currently the only licensed vaccine against tuberculosis (TB). By collecting blood and lung samples from participants, the study aims to identify immune markers that indicate protection against Mycobacterium tuberculosis infection. The research will also explore how durable this protection is, particularly in adolescents who are at high risk for TB. This could lead to better vaccination strategies and improved outcomes for those at risk of TB.

Who could benefit from this research

Good fit: Ideal candidates for this research include adolescents who have received the BCG vaccine and are at risk for tuberculosis infection.

Not a fit: Patients who have not received the BCG vaccine or those who are not at risk for tuberculosis may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to enhanced vaccination strategies that provide longer-lasting protection against tuberculosis.

How similar studies have performed: Previous research has shown promising results in understanding immune responses to the BCG vaccine, indicating that this approach could yield valuable insights.
