NCT ID NCT05500417

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage trial tested a new vaccine (CJCV2) designed to protect against Campylobacter infection, a leading cause of foodborne illness. Fifty-nine healthy adults received three different doses of the vaccine, with or without an immune-boosting adjuvant (ALFQ). The main goal was to check safety and see how well the vaccine triggers an immune response.

Active substance
Campylobacter jejuni conjugate vaccine (CJCV2) with or without Army Liposome Formulation containing QS-21 (ALFQ) adjuvant
What this could lead to
If successful, this could lead to a vaccine that prevents Campylobacter infection, a common cause of food poisoning.
What could go wrong
This is a very early Phase 1 trial with only 59 healthy adults, focused on safety and immune response. It is too soon to know if the vaccine will actually prevent infection in real-world settings.
