Inclusion criteria
Inclusion criteria: - Participant must be healthy in the Investigator’s clinical judgment on the basis of medical history, physical examination and vital signs performed at Screening - Participant must be healthy on the basis of clinical laboratory tests and electrocardiogram (ECG) (only in participants >50 years) performed at Screening. If the results of the laboratory screening tests and ECG are outside the institutional 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 - A woman of childbearing potential must have a negative urine ß-human chorionic gonadotropin [beta-hCG] pregnancy test at Screening and a negative urine [beta-hCG] pregnancy test immediately prior to each study vaccine administration - A man who is sexually active with a woman of childbearing potential must be willing to use condoms for sexual intercourse beginning prior to Dose-1 vaccination until at least 3 months after the Dose-2 vaccination, unless a vasectomy was performed more than 1 year prior to Screening - Participant must pass the test of understanding (TOU) - Additional Inclusion Criteria for HIV-infected participants a) participants must have a positive HIV-1 and/or -2 serology test within 6 months of screening, including the day of screening; b) participants must have a Screening CD4+ cell count >200 cells/microliter (mcL); c) in part 1, all participants must be on a stable highly active antiretroviral therapy (HAART) regimen for 4 weeks prior to Screening, in part 2 participants with screening CD4+ cell count <350 cells/mcL must also be on a stable HAART regimen for 4 weeks prior to Screening
Exclusion criteria
Exclusion criteria: - Has received any candidate Ebola vaccine - Diagnosed with Ebola virus disease, or prior exposure to EBOV, including travel to epidemic Ebola areas less than 1 month prior to Screening - Has received any experimental candidate Ad26- or MVA-based vaccine in the past or received any other investigational drug or investigational vaccine or used an invasive investigational medical device within 3 months prior to Screening - Known allergy or history of anaphylaxis or other serious adverse reactions to vaccines or vaccine products - Presence of significant conditions (eg, history of seizure disorders, (auto) immune disease or deficiency, any spleen disease, active malignancy, ongoing tuberculosis treatment, other systemic infections) or clinically significant findings during screening of medical history, ECG (only in participants >50 years), physical examination, vital signs or laboratory testing for which, in the opinion of the investigator, participation would not be in the best interest of the participants (eg, compromise the safety or well-being) or that could prevent, limit, or confound the protocol-specified assessments
