Why TB vaccines protect some people better than others
Project 3 Determinants of Vaccine Efficacy
['FUNDING_P01'] · UNIV OF MASSACHUSETTS MED SCH WORCESTER · NIH-11173674
This project looks at why the BCG vaccine protects some people against tuberculosis more than others by studying immune and genetic differences using diverse animal models.

What this research studies
Researchers use genetically diverse mouse models that mimic human variation to see how BCG vaccination triggers different immune responses. They measure immune cell types and gene activity after vaccination to find patterns linked to protection. The team will also refine small-animal models so future vaccine candidates can be tested more reliably. Findings aim to point to markers that predict who will be protected and guide better vaccine designs.
Who could benefit from this research
Good fit: People who have received BCG vaccination, those at risk for TB, or volunteers willing to provide blood or other samples for immune and genetic studies would be the most relevant participants or donors.
Not a fit: People seeking immediate treatment for active TB are unlikely to get direct clinical benefit from this preclinical vaccine research.
Why it matters
Potential benefit: If successful, this work could help develop vaccines or tests that protect more people from tuberculosis by identifying immune markers of protection.
How similar studies have performed: BCG protects some people but results have been mixed and many newer TB vaccine candidates have not yet shown clear protection, so this approach builds on known variability rather than testing an established cure.
