Exclusion Criteria:

Has been diagnosed with Ebola disease, or exposed to Ebola including travel to West Africa* in 2014-2016.
- Note: West Africa includes but is not limited to the countries of Guinea, Liberia, Mali, and Sierra Leone. Subjects who anticipate traveling to epidemic Ebola areas before the end of the study will also be excluded from enrollment into the study.
- Known or suspected receipt of an adenovirus serotype 26 (Ad26)-based vaccine.
- Known or suspected receipt of any licensed or investigational small pox (vaccinia)-based vaccine* *Note: Includes any MVA-based candidate vaccine (Imvamune or Imvanex), Dryvax, or Acam2000. Military history should be reviewed with potential subjects for receipt of vaccinia-based vaccine. The presence of a typical vaccinia scar should be considered exclusionary.
- Positive serology for human immunodeficiency virus (HIV)
- Positive Hepatitis B surface antigen
- Positive antibody to Hepatitis C virus (HCV)
Known allergy or history of anaphylaxis or other serious adverse reactions to vaccines or vaccine products*.
*Note: This includes a known allergy to egg, egg products and aminoglycosides or any of the constituents of the study vaccines [e.g., polysorbate 80, ethylenediaminetetraacetic acid (EDTA), L-histidine, tris (hydroxymethyl)-amino methane (THAM)).

If acute illness prevents administration of vaccine within the 28 day screening window, the potential subject can be enrolled once the acute illness resolves after repeating safety laboratories and if the subject is otherwise eligible. The ECG does not need to be repeated as it is not a safety laboratory and unlikely to change without clinical event in this age group of volunteers.

History of myocarditis, pericarditis, cardiomyopathy, transient ischemic attack or stroke, myocardial infarction, angina, coronary artery disease, congestive heart failure, or arrhythmia*.
*Note: This includes any clinically significant arrhythmia requiring medication, treatment, or clinical follow-up.
Electrocardiogram (ECG) with clinically significant findings,* or features that would interfere with the assessment of myocarditis/pericarditis.
*Clinical significant findings include the following:
a. Conduction disturbance (complete left or complete right bundle branch block or nonspecific intraventricular conduction disturbance with QRS > / = 120 ms, PR interval > / = 210 ms, any second- or third-degree atrioventricular block, or prolongation of the QT interval corrected according to Bazett's formula [QTcB] [> 450 ms]) b.

d. ST-elevation consistent with ischemia or evidence of past or evolving myocardial infarction.
18. History of diabetes mellitus type 1 or type 2*, including cases controlled with diet alone.
Note: A history of isolated gestational diabetes is not an exclusion criterion. 19. Thyroidectomy or thyroid disease requiring medication during the last 12 months.
20. Uncontrolled hypertension, defined as systolic blood pressure > / = 140 mmHg or diastolic blood pressure > / = 90 mmHg.*
Note: Vital signs must be normal by protocol toxicity grading scale or determined to be normal-variant by investigator. In the event of an abnormal heart rate or blood pressure due to physiological variation or activity, the subject may rest for 10 minutes in a quiet room, and then blood pressure and/or heart rate may be re-measured. Repeated vital signs may be used to determine eligibility.
21. Received a licensed live vaccine within 30 days prior to enrollment in this study, or plans to receive a licensed live vaccine within 30 days before or after each study vaccine.

Note: Participation in an observational clinical study is allowed. 25. Receipt of blood products or immunoglobulin in the past 3 months. 26. Donation of a unit of blood within 8 weeks before Day 1 or plans to donate blood during participation in the study (from the start of screening onwards).
27. Major psychiatric illness during the past 12 months that in the opinion of the investigator would preclude participation.
28. Current or past abuse of recreational or narcotic drugs.*
Note: Urine will be tested only at screening to check for use of amphetamines, benzodiazepines, cocaine, and opioids.
29. Current or past alcohol use judged by the investigator to potentially interfere with subject study adherence.
30. History of chronic urticaria (recurrent hives). 31. Chronic or recurrent use of medications which modify host immune response (e.g., cancer chemotherapeutic agents, parenteral corticosteroids).*
Note: This is defined as greater than 2 weeks duration within three months prior to vaccination or current use of immunosuppressive medication:

c. Oral/parenteral corticosteroids given for non-chronic conditions not expected to recur are permissible if the length of therapy was < / = 14 days with completion at least 30 days prior to enrollment.
32. Subject who cannot communicate reliably with the investigator. 33. Subject who, in the opinion of the investigator, is unlikely to adhere to the requirements of the study.
34. Any condition that, in the opinion of the investigator, might interfere with assessing the study objectives.
