Sanofi Pasteur, one of the leading vaccine manufacturers in the world, is in the midst of its Phase III clinical trial called Cdiffense to study its investigational vaccine to prevent Clostridium difficile infection (CDI). The trial is now in more than 20 countries across 5 continents to evaluate the safety, immunogenicity and efficacy of an investigational vaccine for the prevention of primary, symptomatic CDI.

The investigational C. diff vaccine is designed to produce an immune response that targets the toxins generated by C. diff bacteria, which can cause inflammation of the gut. The investigative vaccine ultimately may help prevent a future infection from occurring. Volunteers for the study should be age 50 or older and planning an upcoming hospitalization or have had at least two hospital stays and have received systemic antibiotics in the past year.
