Arm Intervention/treatment
Experimental: Group 1: RSV Vaccine
Participants will receive a single intramuscular (IM) injection of an adenovirus serotype 26 (Ad26)-based respiratory syncytial virus (RSV) vaccine at a single dose level on Day 1 and Day 365.
Biological: RSV Vaccine
Participants will receive a single IM injection of an Ad26-based RSV vaccine at a single dose level on Day 1 and Day 365.

Placebo Comparator: Group 2: Placebo
Participants will receive a single IM injection of placebo control on Day 1 and Day 365.
Biological: Placebo
Participants will receive a single IM injection of placebo control on Day 1 and Day 365.




Primary Outcome Measures :
  1. Percentage of Participants with Protocol Defined Respiratory Syncytial Virus (RSV)-mediated Lower Respiratory Tract Disease (LRTD) Confirmed by Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) [ Time Frame: Up to 1.6 years ]
    Percentage of participants with protocol defined RSV-mediated LRTD confirmed by RT-PCR will be reported.


Secondary Outcome Measures :
  1. Percentage of Participants with any RT-PCR-confirmed RSV Disease [ Time Frame: Up to 1.6 years ]
    Percentage of participants with any RT-PCR-confirmed RSV disease will be reported. RT-PCR-confirmed RSV disease is defined as new onset or worsening of any of the clinical symptoms (lower respiratory tract infection [LRTI], upper respiratory tract infection [URTI]) in combination with RSV confirmation by RT‑PCR.

  2. Percentage of Participants with Protocol Defined RSV-mediated LRTD Confirmed by Serology [ Time Frame: Up to 1.6 years ]
    Percentage of participants with protocol defined RSV-mediated LRTD confirmed by serology will be reported.

  3. Percentage of Participants with Any Serology-confirmed RSV Disease [ Time Frame: Up to 1.6 years ]
    Percentage of participants with any serology-confirmed RSV disease will be reported. Serology-confirmed RSV disease is defined as new onset or worsening of any of the clinical symptoms (LRTI and URTI) in combination with serology confirmation of RSV.

  4. RSV Neutralization Assay [ Time Frame: Day 1 and Day 15 after each vaccination (up to 1.6 years) ]
    Analysis of neutralizing antibodies to RSV A strain will be performed.

  5. RSV Fusion Protein (F Protein) Binding Antibodies [ Time Frame: Day 1 and Day 15 after each vaccination (up to 1.6 years) ]
    Analysis of antibodies binding to RSV F protein in pre-fusion (pre-F) and/or post-fusion (post-F) form will be performed by enzyme-linked immunosorbent assay (ELISA).

  6. RSV Glycoprotein (G Protein) Binding Antibodies [ Time Frame: Day 3 to Day 5 and Day 29 of acute respiratory infection (ARI) episode ]
    Analysis of antibodies binding to RSV G protein will be performed by ELISA.

  7. Interferon Gamma (IFN-gamma) Enzyme-Linked Immunospot (ELISpot) Assay [ Time Frame: Day 1 and Day 15 after each vaccination (up to 1.6 years) ]
    IFN-gamma ELISpot assay will be performed to assess T-cell IFN-gamma responses to RSV F protein peptides.

  8. Percentage of Participants With Solicited Local Adverse Events (AEs) [ Time Frame: 7 days after each vaccination (Up to Day 372) ]
    Solicited local AEs includes erythema, swelling, and pain/tenderness.

  9. Percentage of Participants With Solicited Systemic AEs [ Time Frame: 7 days after each vaccination (Up to Day 372) ]
    Solicited systemic AEs includes fatigue, headache, nausea, myalgia, and fever (defined as an endogenous elevation of body temperature greater than or equal to [>=]38.0 degree Celsius, as recorded in at least one measurement).

  10. Percentage of Participants With Unsolicited AEs [ Time Frame: 28 days after each vaccination (Up to Day 393) ]
    Unsolicited AEs are all AEs for which the participant is specifically not questioned in the participant eDiary.

  11. Percentage of Participants With Serious Adverse Events (SAEs) [ Time Frame: 6 months after each vaccination or until the end of the corresponding RSV season, whichever occurs later (up to 1.6 years) ]
    An adverse event (AE) is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. A 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.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Participant must have a body mass index (BMI) less than (<)40 kilogram per meter square (kg/m^2)
  • Before randomization, a woman must be: postmenopausal (postmenopausal state is defined as no menses for 12 months without an alternative medical cause); and not intending to conceive by any methods
  • Participant must be either in good or stable health. Participants may have mild to moderate underlying illnesses such as chronic cardiac diseases and chronic lung disease (asthma and chronic obstructive pulmonary disease [COPD]), congestive heart failure (CHF), hypertension, type 2 diabetes mellitus, hyperlipoproteinemia, or hypothyroidism, as long as their symptoms and signs are stable and medically controlled in the judgment of the investigator. Participants will be included on the basis of physical examination, medical history, and vital signs performed between informed consent form (ICF) signature and vaccination on Day 1
  • From the time of vaccination through 3 months after vaccination, participant agrees not to donate blood
  • Participant must be able to read, understand, and complete questionnaires in the eDiary
  • Participant must be willing to provide verifiable identification, have means to be contacted and to contact the investigator during the study

Exclusion Criteria:

  • Participant has an acute illness (including acute respiratory illnesses) or body temperature greater than or equal to (>=)38.0 degree Celsius (ºC) within 24 hours prior to administration of study vaccine. In such a situation, enrollment at a later date is permitted
  • Participant has a severe or potentially life-threatening chronic disorder such as severe chronic cardiac diseases and severe chronic lung disease (asthma and COPD), advanced CHF, end-stage renal disease with or without dialysis, clinically unstable cardiac disease, Alzheimer's disease, or has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (example: compromise well-being) or that could prevent, limit, or confound the protocol-specified assessments
  • Participant has a history of malignancy within 5 years before screening (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy, which is considered cured with minimal risk of recurrence)
  • Per medical history, participant has chronic active hepatitis B or hepatitis C infection
  • Per medical history, participant has human immunodeficiency virus (HIV) type 1 or type 2 infection
  • Participant has a known allergy, or history of anaphylaxis or other serious adverse reactions to vaccines or vaccine components (including any of the constituents of the study vaccine)
