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.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

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.
