Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Administration of immunoglobulins and/or any blood products within the 120 days preceding study entry or planned administration during the study period
  • History of blood donation within 60 days of enrollment or plans to donate within the study period
  • Administration of chronic (defined as more than 14 days) immunosuppressants or other immune modifying drugs within 6 months of study entry

    • For corticosteroids, this will mean prednisone, or equivalent, greater than or equal to 0.5 mg/kg/day
    • Intranasal and topical steroids are allowed

    5. Study Description

    Brief Summary
    Background: Ebola virus has infected and killed people, mostly in Africa. In 2014, the Ebola virus has affected several thousand people. There is no approved effective way to treat or prevent Ebola. Researchers are trying to develop a vaccine for it. Objectives: To study the anti-Ebola vaccine VSV ZEBOV (BPSC1001) to see if it is safe. Also, to see how it affects people's immune system. Eligibility: - Healthy men and women ages 18-65. They must not have a chronic medical condition that requires medicine. They must not be a healthcare worker, an animal care worker, or a childcare worker, and they must not have a household contact that has a compromised immune system, is pregnant, or is under the age of 5 years. Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will be randomly assigned to get the vaccine or the placebo. At visit 1 (vaccination), vital signs will be taken and blood will be drawn. The vaccine or placebo will be injected into the upper arm muscle. Participants will return to the clinic 11 times over the next 6 months. Participants will have blood drawn at every study visit. Their mouth will be swabbed and urine tested at least four times after vaccination. For 14 days after vaccination, participants will write down their temperature, any symptoms, and any redness at the injection site. They will bring the booklet to each study visit. All visits take place at the Canadian Center for Vaccinology, Dalhousie University/IWK Health Centre, Halifax, NS.
