The purpose of this study is to demonstrate non-inferiority in terms of humoral immune responses of Ad26.RSV.preF-based study vaccine lots representative of different aged vaccine in comparison to a non-aged Ad26.RSV.preF-based study vaccine lot.

Ad26.RSV.PreF-based Vaccine

A Randomized, Double-blind Phase 3 Study to Assess the Immunogenicity and Safety of an Ad26.RSV.PreF-based Regimen at the End of Shelf-life in Adults Aged 60 to 75 Years

GMTs of pre-F antibodies as assessed by ELISA at 14 days post administration of Ad26/protein preF RSV vaccine were reported.

RSV A2 strain neutralizing antibody titers of the vaccine-induced immune response was assessed through virus neutralization assay at 14 days post administration of Ad26/protein preF RSV-based vaccine were expressed as 50 percent (%) inhibitory concentration (IC50) units.

Number of participants with solicited local AEs 7 days post vaccination were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Solicited local AEs were precisely defined events that participants were specifically asked about and which were noted by participants in the diary. Solicited local AEs that included injection site pain/tenderness, erythema and swelling at the study vaccine injection site, were used to assess the reactogenicity of the study vaccine and were pre-defined local (injection site).

Number of participants with solicited systemic AEs 7 days post vaccination were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Solicited systemic events include events such as fatigue, headache, nausea, myalgia, and pyrexia, for which participants were specifically questioned and which were noted by participants in their participant diary for 7 days post vaccination (day of vaccination and the subsequent 7 days).

Number of participants with unsolicited AEs 28 days post vaccination were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Unsolicited AEs were all AEs for which the participant was not specifically questioned in the participant diary.

Number of participants with SAEs until 6 months post vaccination were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. An SAE is any untoward medical occurrence that at any dose may result in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product.

Number of participants with AESIs until 6 months post vaccination were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Thrombosis with thrombocytopenia syndrome (TTS) was considered as an AESI.

Participants will receive a single intramuscular (IM) injection of Ad26.RSV.PreF-based vaccine on Day 1 (non-aged lot).

Participants will receive a single IM injection of Ad26.RSV.PreF-based vaccine on Day 1 (aged lot 1).

Participants will receive a single IM injection of Ad26.RSV.PreF-based vaccine on Day 1 (aged lot 2).
