Up to 28 days post vaccination on Day 1 (up to Day 29)
Number of Participants With Serious Adverse Events (SAEs) Until 6 Months Post Vaccination
From Day 1 up to 6 months post vaccination on Day 1 (up to Day 183)
- +1 more secondary outcomes
Study Arms (3)
Group 1: Ad26.RSV.PreF-based Vaccine
EXPERIMENTALParticipants will receive a single intramuscular (IM) injection of Ad26.RSV.PreF-based vaccine on Day 1 (non-aged lot).
Group 2: Ad26.RSV.PreF-based Vaccine
EXPERIMENTALParticipants will receive a single IM injection of Ad26.RSV.PreF-based vaccine on Day 1 (aged lot 1).
Group 3: Ad26.RSV.PreF-based Vaccine
EXPERIMENTALParticipants will receive a single IM injection of Ad26.RSV.PreF-based vaccine on Day 1 (aged lot 2).
Interventions
Ad26.RSV.PreF-based Vaccine will be administered as single IM injection.
Eligibility Criteria
You may qualify if:
- Before randomization, a participant must be: a) postmenopausal (postmenopausal state is defined as no menses for 12 months without an alternative medical cause); and b) not intending to conceive by any methods
- From the time of vaccination through 3 months after vaccination, agrees not to donate blood
- In the investigator's clinical judgment, a participant must be in stable health at the time of vaccination. Participants may have underlying illnesses such as hypertension, congestive heart failure, chronic obstructive pulmonary disease, Type 2 diabetes, hyperlipoproteinemia, or hypothyroidism, as long as their symptoms and signs are stable at the time of vaccination, and these conditions receive routine follow-up by the participant's healthcare provider. Participants will be included on the basis of medical history and vital signs performed between informed consent form (ICF) signature and vaccination
- Must be able to read, understand, and complete questionnaires in the electronic diary (eDiary)
- Must be willing to provide verifiable identification, has means to be contacted and to contact the investigator during the study
- Must be able to work with smartphones/tablets/computers
You may not qualify if:
- Known or suspected allergy or history of anaphylaxis or other serious adverse reactions to vaccines or their excipients (including specifically the excipients of the study vaccine)
- Abnormal function of the immune system resulting from clinical conditions or medication
- Per medical history, participant has chronic active hepatitis B or hepatitis C infection
- History of acute polyneuropathy (example, Guillain-Barré syndrome) or chronic idiopathic demyelinating polyneuropathy
- Has had major surgery (per the investigator's judgment) within 4 weeks before administration of the study vaccine or will not have recovered from surgery per the investigator's judgment at time of vaccination
- Has had major psychiatric illness and/or drug or alcohol abuse which in the investigator's opinion would compromise the participant's safety and/or compliance with the study procedures
