How the immune system and vaccines can help people clear hepatitis C

Mechanisms of spontaneous and vaccine mediated hepatitis C virus control to direct rational development of a novel HCV vaccine

['FUNDING_OTHER'] · JOHNS HOPKINS UNIVERSITY · NIH-11076719

This work looks at how people’s immune systems and candidate vaccines help some people clear hepatitis C, aiming to guide better vaccines for people at risk of infection.

What this research studies

Researchers will compare T cell and antibody responses in people who naturally clear hepatitis C and in volunteers given experimental vaccine candidates. They will analyze blood samples and immune cells, including from people repeatedly exposed who controlled reinfection, to find immune patterns linked to virus control. The team will use those immune signatures to design vaccine components that aim to produce broadly neutralizing antibodies and strong T cell responses. Participation may include blood draws, clinic visits, and follow-up monitoring at Johns Hopkins or affiliated sites.

Who could benefit from this research

Good fit: Ideal candidates include people with prior hepatitis C infection (especially those who cleared it), people at high risk of exposure, and healthy volunteers willing to take part in vaccine research and blood sampling.

Not a fit: People without any history of hepatitis C exposure or those unable or unwilling to provide blood samples or attend study visits are unlikely to get direct benefits from participation.

Why it matters

Potential benefit: If successful, this work could lead to an effective hepatitis C vaccine that prevents new infections and reduces liver disease worldwide.

How similar studies have performed: Previous vaccine work produced strong T cell responses and lowered peak virus levels but did not prevent chronic infection, while natural clearance with broadly neutralizing antibodies has been observed, so this approach builds on partial successes.
