Group Intervention Description Co-administration Group RSVPreF3 OA investigational vaccine Participants received both herpes zoster recombinant subunit (HZ/su) vaccine and respiratory syncytial virus prefusion protein 3 older adult (RSVPreF3 OA) vaccine on Day 1 followed by second dose of HZ/su vaccine on Day 61. Control Group HZ/su vaccine Participants received HZ/su vaccine on Day 1 and RSVPreF3 OA vaccine on Day 31 followed by second dose of HZ/su vaccine on Day 61. Co-administration Group HZ/su vaccine Participants received both herpes zoster recombinant subunit (HZ/su) vaccine and respiratory syncytial virus prefusion protein 3 older adult (RSVPreF3 OA) vaccine on Day 1 followed by second dose of HZ/su vaccine on Day 61. Control Group RSVPreF3 OA investigational vaccine Participants received HZ/su vaccine on Day 1 and RSVPreF3 OA vaccine on Day 31 followed by second dose of HZ/su vaccine on Day 61.
- Primary Outcome Measures
Name Time Method Adjusted Geometric Mean Concentration (GMC) of Anti-glycoprotein E (gE) Antibodies at 1 Month Post-second Dose of HZ/su Vaccination At 1 month post-second dose of HZ/su vaccination (Day 91) Anti-gE antibodies were measured with enzyme linked immunosorbent assay (ELISA) and the results were expressed as GMC, in milli international units per milliliter (mIU/mL).
Adjusted GMTs of RSV-B Neutralizing Titers (ED60) at 1 Month After the RSVPreF3 OA Vaccination At Day 31 for Co-administration Group and at Day 61 for Control Group Neutralizing titers were measured with neutralization assay and the results were expressed as GMT. The ED60 was defined as the dose that produced an effect in 60% of the population.
Adjusted Geometric Mean Titers (GMT) of Respiratory Syncytial Virus-A (RSV-A) Neutralizing Titers [Estimated Dilution 60 (ED60)] at 1 Month After the RSVPreF3 OA Vaccination At Day 31 for Co-administration Group and at Day 61 for Control Group Neutralizing titers were measured with neutralization assay and the results were expressed as GMT. The ED60 was defined as the dose that produced an effect in 60% of the population.
- Secondary Outcome Measures
Name Time Method Percentage of Participants With Unsolicited Adverse Events Within 30 days (the day of vaccination and 29 subsequent days) after vaccine administration An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study vaccine, which does not necessarily have a causal relationship with study vaccine. An unsolicited AE was an AE that was either not included in the list of solicited events or could be included in the list of solicited events but with an onset outside the specified period of follow-up for solicited events. Unsolicited AEs must had been communicated by participant/participant's caregiver(s) who had signed the informed consent. Unsolicited AEs included both serious and non-serious AEs.
Percentage of Participants With Serious Adverse Events (SAEs) From first dose of study vaccine administration (Day 1) up to 6 months after last dose of study vaccine administration, approximately 241 days An SAE was defined as any untoward medical occurrence that, at any dose, resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event.
Percentage of Participants With Potential Immune-mediated Diseases (pIMDs) From first dose of study vaccine administration (Day 1) up to 6 months after last dose of study vaccine administration, approximately 241 days The pIMD was a subset of adverse events of special interest that included autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune etiology.

Anti-gE antibodies were measured with ELISA.
Vaccine Response Rate (VRR) at 1 Month Post-second Dose of HZ/su Vaccination At 1 month post-second dose of HZ/su vaccination (Day 91) The VRR was defined as the percentage of participants who had at least: a 4-fold increase post-vaccination anti-gE antibody concentration as compared to (over) the pre-vaccination anti-gE antibody concentration (for participants who were seropositive at pre-vaccination); or, a 4-fold increase post-vaccination anti-gE antibody concentration as compared to (over) the anti-gE antibody cut-off value for seropositivity (97 mIU/mL) (for participants who were seronegative at pre-vaccination).
