Detailed Description
This study is being conducted to assess safety and immunogenicity of an experimental ebola vaccine.
An outbreak due to the Ebola Zaire (ZEBOV) strain of unprecedented magnitude and scope and with a high mortality continues to spread across West Africa. No vaccine is currently licensed.
The specific opportunity at hand with rVSVΔG-ZEBOV-GP (BPSC1001) is to achieve long-lasting protective immunity to ZEBOV on a time scale of weeks in humans upon a single-shot vaccination, offering a discrete benefit over prime-boost vaccination protocols. The current outbreak represents a global health emergency and the need for access to therapeutic intervention and vaccines is paramount.
The vaccine investigated in this study might provide a critical tool to suppress future out-breaks of EVD in areas at risk.
This study is 1 of 4 clinical trials currently conducted as part of the WHO-led VEBCON consortium, aiming to generate harmonized data for the rVSVΔG-ZEBOV-GP (BPSC1001) vaccine candidate to allow optimized rapid decisions on dose and safety.

- Known allergy to the components of the BPSC1001 vaccine product or history of life-threatening reactions to vaccine containing the same substances.
- Participation in a clinical trial or use of an investigational product within 30 days or five times the half-life of the investigational drug -prior to receiving the first dose within this study
- Evidence in the subject's medical history or in the medical examination that might influence either the safety of the subject or the absorption, distribution, metabolism or excretion of the investigational product under investigation.
- Any positive result for HIV1/2, HCV antibody or HBs antigen testing.
- Pregnant or lactating females, or females who intend to become pregnant during the study period.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, cytotoxic therapy in the previous 5 years, and/or diabetes

- Any household contact who is immunodeficient, HIV positive or pregnant
- Working with livestock
- Any chronic or active neurologic disorder, including migraines, seizures, and epilepsy, exclud-ing a single febrile seizure as a child
- Known history of Guillain-Barré Syndrome
