Vaccine to prevent liver-fluke–linked bile duct cancer

Anti-cancer vaccine targeting the host-parasite interface during fluke infection

NIH-funded research George Washington University · NIH-11416185

This project aims to create a vaccine that blocks liver fluke infections to help people in places where the parasite is common avoid bile duct cancer.

What this research studies

Liver fluke (Opisthorchis viverrini) infections are common in parts of East Asia and greatly raise the risk of bile duct cancer. Researchers are studying proteins and tiny particles the fluke releases that let it survive and change cells, then choosing several of those parasite molecules as targets for a multi‑component vaccine. The team will test these vaccine candidates in the lab and in preclinical models to see if they stop infection and the early cancer-related changes. If promising, the work would move toward testing in people in areas where the fluke is endemic.

Who could benefit from this research

Good fit: People living in or from liver‑fluke endemic areas (for example Northeast Thailand and Laos) or those with known exposure to raw freshwater fish are the most relevant future candidates.

Not a fit: People without any exposure to liver fluke or whose bile duct cancer is caused by unrelated factors are unlikely to benefit from this vaccine approach.

Why it matters

Potential benefit: If successful, the vaccine could prevent liver fluke infection and substantially reduce bile duct cancer in high‑risk communities.

How similar studies have performed: Some experimental anti‑helminth vaccines have shown promise in animals, but vaccines specifically aimed at preventing liver fluke–driven bile duct cancer are largely new and untested in humans.
