Primary Outcome Measures
NameTimeMethod
Geometric Mean Ratio (GMR) of Neutralizing Titer (NTs) for RSV A and B in RSVpreF + herpes zoster subunit vaccine (HZ/su) Compared to RSVpreF Alone1 month after vaccination with RSVpreF in the RSVpreF + HZ/su coadministration group to RSVpreF alone in the sequential administration group
Anti-gE antibody concentrations expressed as Geometric Mean Concentration (GMC) ratios in RSVpreF + HZ/su Compared to HZ/su Alone1 month after the second dose of HZ/su in the RSVpreF + HZ/su coadministration group to HZ/su alone in the sequential administration group
Percentage of Participants reporting Local Reactions Within 7 Days after VaccinationWithin 7 Days after each vaccination (Vaccination on Day 1)

Describe local reactions (redness, swelling, and pain at the injection site) within 7 days following each study intervention administration recorded by participants in an electronic diary (e-diary).

Percentage of Participants with Systemic Events Within 7 Days after VaccinationWithin 7 Days after each vaccination (Vaccination on Day 1)

Describe systemic events (fatigue, headache, vomiting, nausea, diarrhea, muscle pain, and joint pain) within 7 days following each study intervention administration recorded by participants in an electronic diary (e-diary).

Percentage of Participants with Adverse Events (AEs)from Vaccination through 1 Month after VaccinationWithin 1 Month after last vaccination

Describe AEs occurring through 1 month after each study intervention administration

Percentage of Participants with Serious Adverse Events (SAEs) Throughout the StudyWithin 4 Months after first study vaccination (Vaccination on Day 1)

Describe SAEs occurring through 4 months after the first study intervention administration.

Secondary Outcome Measures
NameTimeMethod
NTs for RSV A and RSV B expressed as Geometric Mean Titers (GMT)Before vaccination with RSVpreF, 1 month after vaccination with RSVpreF

NTs for RSV A and RSV B expressed as seroresponse rate1 month after vaccination with RSVpreF
Anti-gE antibody concentrations expressed as GMCsBefore vaccination and 1 month after the second dose of HZ/su
Anti-gE antibody concentrations expressed as GMFRsBefore vaccination and 1 month after the second dose of HZ/su
Anti-gE antibody concentrations expressed as seroresponse rate1 month after the second dose of HZ/su
