Oxford University Cancer Prevention Vaccine Breakthrough
The INTERCEPT-Lynch study will test whether Moderna’s vaccine can trigger immune responses against early cancer changes in people with Lynch syndrome.
On Tuesday, June 9, 2026, the University of Oxford and Moderna announced the Intercept-Lynch trial, a cancer-prevention vaccine study targeting patients at high risk of bowel and ovarian cancer.
Lynch syndrome affects around 175,000 people in England and increases lifetime bowel cancer risk by around 80 per cent, yet only 5 per cent of carriers are aware they have the condition.
Professor David Church, lead investigator at Oxford, said the vaccine aims to "train the immune system" to recognize abnormalities, acting as "an instruction manual" for attacking pre-cancerous cells.
David Berman, Moderna's chief development officer, said the company aims to apply mRNA technology earlier in the patient journey to "harness the immune system when it can have the greatest impact."
Experts believe the approach could eventually be adapted for other cancer types, while a second study phase including multiple centers across the UK is expected to begin in 2027.
