Are you at risk for a C. diff (Clostridium difficile) infection?
Clostridium difficile (C.diff) infection (CDI) is a contagious and potentially life-threatening condition that can be very difficult to treat. Symptoms range from mild diarrhea to life-threatening colitis and often include dehydration, abdominal pain, and nausea.
C. diff infection can have a significant impact on the lives of people who contract the disease, particularly older adults.
- Have you been hospitalized twice in the past year and received antibiotics?
- Do you have an upcoming surgery, requiring you to be hospitalized for several days?
- Are you 50 years of age or older?
You may be at risk for C. diff.
The Bend Memorial Clinic Research Department is currently recruiting volunteers for a vaccine research trial for the disease of C. diff.

Location: Bend, Oregon (Central Oregon)
Purpose: The aim of this study is to evaluate the efficacy of the candidate Clostridium difficile (C. difficile) vaccine to prevent primary symptomatic C. difficile infection (CDI) in subjects a risk for CDI where there is a substantial unmet medical need.

- Has received systemic (not topical) antibiotics in the 12 months before enrollment, or
Risk Stratum 2:
- Is anticipated to have an in-patient hospitalization for a planned surgical procedure within 60 days of enrollment. The impending hospital stay is planned to be ≥ 72 hours for a surgery involving 1 of the following:
- Kidney/bladder/urinary system
- Musculoskeletal system
- Respiratory system
- Circulatory system
- Central nervous system.
- Subject is pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be post-menopausal for at least 1 year, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to the first vaccination and until at least 4 weeks after the last vaccination)
- Participation in the 4 weeks preceding the first trial vaccination or participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
- Receipt of any vaccine in the 4 weeks preceding the first trial vaccination except for influenza (seasonal or pandemic) and pneumococcal vaccines. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines
- Previous vaccination against C. difficile with either the trial vaccine, another vaccine, or monoclonal antibodies
- Diarrhea on day of enrollment
- Self-reported current or prior CDI episode
- Anticipated or current receipt of kidney dialysis treatment
- History of gastrointestinal surgery for gastrointestinal malignancy (Note: Colonoscopy, polypectomy, and appendectomy are not exclusion criteria.)
- History of inflammatory bowel disease, irritable bowel syndrome, colostomy, or small or large intestine bowel surgery where resection was performed
- Receiving enteral feeding (e.g., nasogastric, gastrostomy, and jejunostomy tube feeding)
- Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
- Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccine used in the trial or to a vaccine containing any of the same substances
- Self-reported thrombocytopenia, contraindicating intramuscular vaccination
- Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
- Current alcohol abuse or drug addiction that might interfere with the ability to comply with trial procedures in the opinion of the Investigator
- Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion
- Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature ≥ 38.0°C [≥ 100.4°F]). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided
- Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study.
