Brief Summary:
The purpose of this study is to assess the safety/tolerability of the 2 different vaccine regimens of priming with trivalent Ad26.Mos.HIV and boosting with trivalent Ad26.Mos.HIV and Clade C gp140 plus adjuvant or priming with tetravalent Ad26.Mos4.HIV and boosting with Ad26.Mos4.HIV and Clade C glycoprotein (gp)140 plus adjuvant. Immune responses of the different vaccine schedules will be assessed.

Total dose is 5*10^10 viral particle per 0.5mL injection administered intramuscularly. Biological: Clade C gp140 Clade C gp140 vaccine containing 250 mcg of total protein, mixed with aluminum phosphate adjuvant, per 0.5 mL injection administered intramuscularly. |
|
Placebo Comparator: Group 2B: Placebo
Participants will receive placebo at Weeks 0, 12, 24 and 48.
|
Drug: Placebo
Normal saline 0.9 percent (%), 0.5 mL injection administered intramuscularly. |
Primary Outcome Measures :
- Local And Systemic Solicited Adverse Events (Aes) for 7 Days Post-Vaccination [ Time Frame: Baseline up to 7 days after each vaccination ]Participants will be asked to note occurrences of local reactions: pain/tenderness, erythema, swelling/induration at the injection site, and systemic events: fever (temperature measurement), fatigue, headache, nausea, myalgia and chills daily for 7 days post-vaccination.
- AEs for 28 Days After Each Vaccination [ Time Frame: Baseline up to 28 days after each vaccination ]
- Discontinuations From Vaccination/From Study Due to AEs [ Time Frame: Baseline up to Week 72 ]

Criteria
Inclusion Criteria:
- Are negative for human immunodeficiency virus (HIV) infection at screening
- Is healthy on the basis of physical examination, medical history, electrocardiogram (ECG), and vital signs measurement performed at screening
- Are willing/able to adhere to the prohibitions and restrictions specified in the protocol and study procedures
- Female participants of childbearing potential must have a negative serum pregnancy test (beta human chorionic gonadotropin [beta hCG]) at the Screening visit, and a negative urine pregnancy test pre-dose on Day 1
- Are assessed by the clinic staff as being at low risk for HIV infection
Exclusion Criteria:
- Has chronic hepatitis B (measured by hepatitis B surface antigen test) or active hepatitis C (measured by hepatitis C virus [HCV] Ab test; if positive, HCV ribonucleic acid [RNA] PCR test will be used to confirm active versus past HCV infection), active syphilis infection, chlamydia, gonorrhea, or trichomonas . Active syphilis documented by serology unless positive serology is due to past treated infection
- Has had a thyroidectomy or active thyroid disease requiring medication during the last 12 months (not excluded: a stable thyroid supplementation)
- Has had major psychiatric illness and/or substance abuse problems during the past 12 months (including hospitalization or periods of work disability) that in the opinion of the investigator would preclude participation
- Has been in receipt of any licensed vaccine within 14 days prior to the first dose of study vaccine/placebo, plans to receive within 14 days after the first study vaccination, or plans to receive within 14 days before or after the second, third or fourth vaccination
- Is a recipient of a prophylactic or therapeutic HIV vaccine candidate at any time, or a recipient of other experimental vaccine(s) within the last 12 months prior to the Day 1 visit (Vaccination 1). For participants who received an experimental vaccine (except HIV vaccine) more than 12 months prior to the Day 1 visit (Vaccination 1), documentation of the identity of the experimental vaccine must be provided to the sponsor, who will determine eligibility on a case-by-case basis
