Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Participant must be a Japanese participant whose parents and grandparents are Japanese as determined by the participant's verbal report
  • Before randomization, a woman must be: postmenopausal (A postmenopausal state is defined as no menses for 12 months without an alternative medical cause); not intending to conceive by any methods
  • A male participant must agree not to donate sperm for the purpose of reproduction for a minimum 28 days after receiving the dose of study vaccine
  • In the investigator's clinical judgment, participant must be either in good or stable health. Participants may have underlying illnesses such as hypertension, type 2 diabetes mellitus, hyperlipoproteinemia, or hypothyroidism, as long as their symptoms/signs are medically controlled. If they are on medication for a condition, the medication dose must have been stable for at least 12 weeks preceding vaccination and expected to remain stable for the duration of the study. Participants will be included on the basis of physical examination, medical history, vital signs , and 12-lead electrocardiogram (ECG) performed at screening
  • From the time of vaccination through 3 months, participant agrees not to donate blood
  • 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 a serious chronic disorder, including severe chronic obstructive pulmonary disease or clinically significant congestive heart failure, 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 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)
  • Participant has chronic active hepatitis B or hepatitis C infection, documented by hepatitis B surface antigen and hepatitis C antibody, respectively
  • Participant 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
  • Participant has a history of chronic urticaria (recurrent hives), eczema and/or atopic dermatitis

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Solicited Local Adverse Events (AEs) After Vaccination
Time Frame: 7 days after vaccination (Day 1 to Day 8)
Number of participants with solicited local AE's will be evaluated. Solicited local AEs (including erythema, swelling, and pain/tenderness at the study vaccine injection site) will be noted in the participant diary after 7 days of vaccination.
7 days after vaccination (Day 1 to Day 8)
Number of Participants with Solicited Systemic Adverse Events (AEs) After Vaccination
Time Frame: 7 days after vaccination (Day 1 to Day 8)
Number of participants with solicited systemic AEs will be evaluated. Solicited systemic AEs (fatigue, headache, myalgia, nausea and fever) will be noted in the participant diary after 7 days of vaccination.
7 days after vaccination (Day 1 to Day 8)
Number of Participants with Unsolicited AEs
Time Frame: 28 days after vaccination (Day 1 to Day 29)
Number of participants with unsolicited AEs will be evaluated. An 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. Unsolicited AEs will include all AEs for which the participant is not specifically questioned in the participant diary.
28 days after vaccination (Day 1 to Day 29)
Number of Participants with Serious Adverse Events (SAEs)
Time Frame: First vaccination (Day 1) to the end of the study (up to Day 183)
Number of participants with SAEs will be evaluated. A SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life threatening experience, is a congenital anomaly/birth defect, is suspected transmission of any infectious agent via a medicinal product, is medically important, and may jeopardize participant or may require medical or surgical intervention to prevent one of the outcomes listed above.
First vaccination (Day 1) to the end of the study (up to Day 183)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
RSV Neutralization Assay
Time Frame: Day 1 (pre-vaccination), Days 14, 28, and 182 (post-vaccination)
Analysis of neutralizing antibodies to RSV A strain will be performed.
Day 1 (pre-vaccination), Days 14, 28, and 182 (post-vaccination)
RSV Fusion Protein (F-Protein) Binding Antibodies by Enzyme-linked Immunosorbent Assay (ELISA)
Time Frame: Day 1 (pre-vaccination), Days 14, 28, and 182 (post-vaccination)
Antibodies binding to RSV F-protein in pre-fusion and post-fusion forms will be assessed by ELISA.
Day 1 (pre-vaccination), Days 14, 28, and 182 (post-vaccination)
Interferon (IFN)-Gamma Enzyme-Linked Immunospot (ELISpot) Assay
Time Frame: Day 1 (pre-vaccination) and Day 29 (post-vaccination)
RSV F-specific cellular immune responses elicited by the different vaccine regimens.
Day 1 (pre-vaccination) and Day 29 (post-vaccination)
