A study to evaluate the safety and immunogenicity of a candidate Ebola Vaccine in children

Subject’s parent(s)/ legally acceptable representative(s) (LAR[s]) who, in the opinion of the Investigator, can and will comply with the requirements of the protocol (e.g. availability for Diary Card completion, return for follow-up visits, availability for clinical follow-up throughout the study period).

• Written/ thumb printed informed consent obtained from the subject’ parent(s)/ LAR[s] prior to performing any study specific procedure. In addition, written/ thumb printed in-formed assent should be obtained if appropriate (from all subjects aged 13 to 17 years and from younger subjects as per local requirements).
• A male or female child aged 1 to 17 years inclusive at the time of Screening.
• Subjects with a negative RDT test for Malaria within 30 days prior to randomisation into the study. OR Subjects with a positive RDT test for Malaria who completed antimalarial treatment at least 5 days prior to randomisation into the study.
• 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.

• Female subjects of childbearing potential may be enrolled in the study, if the subject:

Child in care.

• Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine during the period starting 30 days before the Day 0 visit, or planned use during the study period.
• 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:
• Clinically significant immunosuppressive or immunodeficient condition (e.g. clinical acquired immune deficiency syndrome [AIDS]).
• Major congenital defects.
• Malnutrition (defined as weight for age Z-score less than -3, or other clinical signs of malnutrition).
• Any clinically significant haematological or biochemical laboratory abnormality.
• Pregnant female.
• Any condition that in the Investigator’s opinion may po-tentially compromise subject safety or interfere with sub-ject assessment or compliance.
