contraception for the entire study.
*Child-bearing potential is defined as not sterilized via tubal ligation, bilateral
oophorectomy, salpingectomy, hysterectomy, or successful Essure (R) placement
(permanent, non-surgical, non-hormonal sterilization) with documented radiological
confirmation test at least 90 days after the procedure, and still menstruating or <1
year of the last menses if menopausal.

spermicide, effective intrauterine devices, NuvaRing (R), and licensed hormonal
methods such as implants, injectables, or oral contraceptives ("the pill").

hours prior to enrollment.
12. Agree not to participate in another interventional clinical trial during the study
period that may affect the analysis or endpoint assessment.

Exclusion Criteria:
1. Have any disease or medical condition that, in the opinion of the site PI or
appropriate sub-investigator, is a contraindication to study participation*.
*Including acute or chronic disease or medical condition that would place the subject
at an unacceptable risk of injury, render the subject unable to meet the requirements
of the protocol, or may interfere with the evaluation of responses or the subject's
successful completion of this trial.
These include:
History of inflammatory bowel disease (IBD) (including ulcerative colitis, Crohn's
disease, indeterminate colitis, or celiac disease). Within the past 12 months, has any
of the following: irritable bowel syndrome (IBS) or any active uncontrolled
gastrointestinal disorders or diseases as assessed by the investigator, including
symptoms or evidence of active gastritis or gastroesophageal reflux disease, gastric
surgery or gastric acid hyper-secretory disorders (e.g., Zollinger-Ellison syndrome),
gastrointestinal obstruction, ileus, gastric retention, bowel perforation, toxic
colitis, persistent infectious gastroenteritis, persistent or chronic diarrhea of
unknown etiology, Clostridium difficile infection. History of immunodeficiency due to
congenital or hereditary causes, underlying illness or treatment, autoimmune
disorders, or chronic inflammatory disorders. History of an inflammatory arthritis
such as reactive arthritis, Reiter's syndrome, ankylosing spondylitis, rheumatoid
arthritis, or GBS. Known active neoplastic disease non-melanoma, treated, skin cancers
are permitted, a history of any hematologic malignancy, or have used anticancer
chemotherapy/radiation therapy (cytotoxic) within 5 years prior to study vaccination.
Other condition requiring daily therapy that would place the volunteer at increased
risk or Adverse Events (AE). Other laboratory abnormalities which in the opinion of
the investigator precludes participation in the study. Clinically significant
abnormalities on physical exam.
2. Documented history of auto-immune conditions in a first-degree relative. Examples
include reactive arthritis, Reiter's syndrome, ankylosing spondylitis, rheumatoid
arthritis, or GBS.
3. History of Potentially Immune-Mediated Medical Conditions (PIMMCs).
4. Evidence of inflammatory arthritis on exam and/or positive serology results for
HLA-B27.
5. Positive Human Immunodeficiency Virus (HIV), Hepatitis B Surface Antigen (HBsAg), or
Hepatitis C antibodies (HCVs).
6. Participation in a previous Campylobacter study or reports having received vaccination
against Campylobacter within the last 3 years.

8. Occupation involving handling of Campylobacter bacteria or vaccine products currently
or in the past 3 years.
9. Use of immunosuppressive/immunomodulating disease therapy within 90 days
10. Received Immunoglobulin (Ig) or other blood products (with exception of Rho D Ig)
within 90 days prior to enrollment.
11. Have a history of severe reactions following previous immunization with any licensed
or unlicensed vaccine.
12. Known hypersensitivity to any components of vaccine, adjuvant or diluent.
13. Received or plan to receive a licensed live vaccine within 30 days prior to 1st

COVID-19 vaccine +/- 7 days from study product vaccination.
15. Individuals in whom the ability to observe possible local reactions at the eligible
injection sites (deltoid region) is unacceptably obscured due to a physical condition
or permanent body art.
16. Within 14 days prior to vaccination has received an oral or parenteral (including
intra-articular) corticosteroid of any dose for 5 or more days, or high-dose inhaled

remaining is allowable if, in the opinion of a study clinician licensed to make
medical diagnoses and listed on the Form FDA 1572 as the site PI or sub-investigator,

as required by the protocol.
22. Received an investigational product within 30 days prior to the first study
