Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects who have provided written informed consent and an authorization for disclosure of protected health information must meet the following criteria:
  • Healthy adult men or women, 18 to 60 (inclusive) years of age.
  • Have provided written informed consent prior to screening procedures.
  • Free of clinically significant health problems, as determined by pertinent medical history, physical examination without significant findings in the 28 days prior to enrollment, and clinical judgment of the Investigator.
  • Agrees not to have, or plan to have, non-study vaccines within 60 days after receiving the initial study vaccine, unless medically indicated (i.e., tetanus, rabies vaccine).
  • Agrees not to have contact with ruminant animals or other hoofed animals such as horses, pigs and cows 7 days after each vaccination.
  • Available, able, and willing to participate for all study visits and procedures through Day 182 (Week 26).
  • Be willing to minimize blood and body fluid exposure of others for 7 days after vaccination by:
  • using effective barrier prophylaxis, such as latex condoms, during penetrative sexual intercourse;
  • avoiding the sharing of needles, razors, or toothbrushes; and
  • avoiding open mouth kissing.
  • Body mass index (BMI) less than 40 kg/m2.
  • Laboratory criteria without clinically significant findings within 28 days prior to enrollment:
  • hemoglobin ≥11.5 g/dL for women and ≥13.5 g/dL for men.
  • white blood cell count ≥3500 cells/mm3.
  • +10 more criteria

You may not qualify if:

  • Any subject who meets any of the following criteria will not qualify for entry into the study:
  • History of prior infection with a filovirus or prior participation in a filovirus vaccine trial.
  • History of prior infection with VSV or receipt of a VSV vectored vaccine.
  • Has traveled to an area where the World Health Organization (WHO) has declared as an Ebola outbreak zone.
  • Healthcare worker who has direct contact with patients (nurse, physician, dentist, emergency medical technician, dental hygienist).
  • Has a household contact (HHC) who is immunodeficient, on immunosuppressive medications, HIV positive, pregnant or breast-feeding, or has an unstable medical condition.
  • Breast-feeding, or is a childcare worker, or HHC, who has direct contact with children, 5 years of age or younger.
  • Direct hands-on job preparing food in the food industry.
  • History of employment in an industry involved in contact with ruminant animals, other hoofed animals such as pigs and horses, veterinary sciences, or other potential exposure to VSV.
  • History of employment or activity that involves potential contact with filoviruses.
  • History of severe local or systemic reactions to any vaccination or a history of severe allergic reactions.
  • Known allergy to any rVSVN4CT1 vectored vaccine component.
  • Receipt of investigational product (IP) up to 30 days prior to randomization or ongoing participation in another clinical trial except observational studies.
  • Receipt of licensed non-live or live vaccines within 30 days prior to planned study immunization.
  • Ability to observe possible local reactions at the eligible injection sites (deltoid region) is, in the opinion of the Investigator, unacceptably obscured due to a physical condition or permanent body art.
  • +16 more criteria
