Outcome Measures
Primary Outcomes (7)
Number of Participants With Unsolicited Adverse Events (Groups 1, 2 and 3)
An adverse event (AE) is any untoward medical occurrence in a clinical study subject administered a medicinal product, it does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal product. Unsolicited adverse events were events which were reported by the participant voluntarily or obtained by means of interviewing the participant in a nondirected manner at study visits.
Up to 42-day post dose 2 visit (Day 1 to Day 127)
Number of Participants With Serious Adverse Events (Groups 1, 2 and 3)
A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Up to Day 365
Number of Participants With Immediate Reportable Events (Groups 1, 2 and 3)
The following neuroinflammatory disorders were considered immediate reportable events and which had to be reported to the sponsor within 24 hours of becoming aware of the event. Neuroinflammatory disorders included: cranial nerve disorders including paralyses/paresis (example: bell's palsy), optic neuritis, multiple sclerosis, transverse myelitis, guillain-barre syndrome including miller fisher syndrome, bickerstaff's encephalitis and other variants, acute disseminated encephalomyelitis, including site-specific variants (example: non-infectious encephalitis, encephalomyelitis, myelitis, myeloradiculomyelitis), myasthenia gravis and lambert-eaton myasthenic syndrome, immune-mediated peripheral neuropathies and plexopathies, including chronic inflammatory, demyelinating polyneuropathy, multifocal motor neuropathy, and polyneuropathies associated with monoclonal gammopathy, narcolepsy, isolated paresthesia of more than 7 days duration.
Up to Day 365
Number of Participants With Solicited Local Adverse Events (Groups 1, 2 and 3)
An AE was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. Solicited local AEs were pre-defined local (at the injection site) AEs for which participants were specifically questioned and which were noted by participants in their diary for 7 days post first vaccination. Solicited local AEs were: injection site pain/tenderness, erythema, induration/swelling, itching at the vaccination site.
7 days post-dose 1 (Day 8)
Number of Participants With Solicited Local Adverse Events (Groups 1, 2 and 3)
An AE was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. Solicited local AEs were pre-defined local (at the injection site) AEs for which participants were specifically questioned and which were noted by participants in their diary for 7 days post first vaccination. Solicited local AEs were: injection site pain/tenderness, erythema, induration/swelling, itching at the vaccination site.
7 days post-dose 2 (Up to Day 92)
Number of Participants With Solicited Systemic Adverse Events (Groups 1, 2 and 3)
An AE was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. Participants were instructed on how to note signs and symptoms in the diary on a daily basis for 7 days post-vaccination (Day of vaccination and the subsequent 7 days) for solicited systemic AEs. Solicited systemic events included fever, headache, fatigue/malaise, myalgia, nausea/vomiting, arthralgia and chills.
7 days post-dose 1 (Day 8)
Number of Participants With Solicited Systemic Adverse Events (Groups 1, 2 and 3)

Eligibility Criteria
You may qualify if:
- Must be healthy in the Investigator's clinical judgment on the basis of medical history, physical examination, electrocardiogram (ECG) and vital signs performed at Screening
- Must be healthy on the basis of clinical laboratory tests performed at Screening. If the results of the laboratory screening tests are outside the normal reference ranges, the participant may be included only if the Investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study
- Before randomization, a woman must be either of childbearing potential and practicing (or intending to practice) a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for participants participating in clinical studies, beginning at least 28 days prior to vaccination OR not of childbearing potential: postmenopausal (greater than \[\>\] 45 years of age with amenorrhea for at least 2 years or lesser than or equal to \[\<=\] 45 years of age with amenorrhea for at least 6 months, and a serum follicle stimulating hormone (FSH) level \>40 international unit per milliliter \[IU/L\]); permanently sterilized (for example, bilateral tubal occlusion \[which includes tubal ligation procedures as consistent with local regulations\], hysterectomy, bilateral salpingectomy, bilateral oophorectomy); or otherwise be incapable of pregnancy
- Woman of childbearing potential must have a negative serum (beta-human chorionic gonadotropin \[beta-hCG\]) at Screening and a negative urine beta-hCG pregnancy test immediately prior to each study vaccine administration
- Man who is sexually active with a woman of childbearing potential and has not had a vasectomy performed more than 1 year prior to screening must be willing to use condoms for sexual intercourse beginning prior to enrollment
You may not qualify if:
- Having received any candidate Ebola vaccine
- Diagnosed with Ebola virus disease, or prior exposure to Ebola virus, including travel to West Africa less than 1 month prior to screening. West Africa includes but is not limited to the countries of Guinea, Liberia, Mali, and Sierra Leone
- Having received any experimental candidate adenovirus serotype 26 (vector: Ad26) or Modified Vaccinia Ankara (MVA-) based vaccine in the past
- Known allergy or history of anaphylaxis or other serious adverse reactions to vaccines or vaccine products (including any of the constituents of the study vaccines including known allergy to egg, egg products and aminoglycosides
- Presence of acute illness or temperature greater than or equal to 38.0 C on Day 1
