A Study to Evaluate the Safety and Immunogenicity of a Candidate Ebola Vaccine in Children
Safety and Immunogenicity Study of GSK Biologicals' Investigational Recombinant Chimpanzee Adenovirus Type 3-vectored Ebola Zaire Vaccine (GSK3390107A) in Children in Africa
The purpose of this study is to assess the safety and reactogenicity of a single IM dose of the GSK3390107A (ChAd3 EBO-Z) vaccine, overall and in children aged 1 to 5, 6 to 12, and 13 to 17 years, separately.
Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational GSK3390107A (ChAd3-EBO-Z) vaccine to afford at least partial protection, all children in the study will receive the investigational GSK3390107A (ChAd3 EBO-Z) vaccine. The children in the Group GSK3390107A+Nimenrix will receive the investigational GSK3390107A (ChAd3-EBO-Z) vaccine at Day 0 of the study, whereas the children in the Group Nimenrix+GSK3390107A will receive Nimenrix at Day 0 (as a control). At Month 6, the children in the Group Nimenrix+GSK3390107A will receive the investigational GSK3390107A (ChAd3-EBO-Z) vaccine (provided that no safety concerns are raised), whereas the children in the Group GSK3390107A+Nimenrix will receive Nimenrix.

- Healthy subjects as per Investigator judgement, as estab-lished by medical history, clinical examination and haema-tology/ biochemistry laboratory parameters screening be-fore entering into the study.
Female subjects of non-childbearing potential may be enrolled in the study.
- Non-childbearing potential is defined as pre-menarche or ovariectomy.

- Previous vaccination with an investigational EBOV or Marburg vaccine, or previous vaccination with a chim-panzee adenoviral vectored investigational vaccine.
- Known prior EBOV or SUDV disease.
- Travel to country affected by the EBOV epidemic or direct contact with person with EVD within 21 days prior to the Day 0 visit.
- History of any reaction or hypersensitivity (such as ana-phylaxis, urticaria (hives), respiratory difficulty, angioe-dema, or abdominal pain) likely to be exacerbated by any component of the study vaccine.
- Planned administration/ administration of a vaccine not foreseen by the study protocol in the period starting 30 days before and ending 30 days after each vaccination visit.
- Acute or chronic illness determined by medical history, clinical examination and laboratory screening tests in-cluding, but not limited to:
