Adult participants aged greater than or equal to (>=) 65 years received a single intramuscular (IM) injection of adenovirus serotype 26 respiratory syncytial virus pre-fusion conformation stabilized F-protein (Ad26.RSV.preF) 1*10^11 viral particles (vp) and RSV preF protein 150 micrograms (mcg) (protein mixture) on Day 1. Participants were divided into revaccination subcohorts: 1A, 1B, and 1C. Participants further received revaccination with the Ad26.RSV.preF 1*10^11 vp and RSV preF protein 150 mcg (protein mixture) at 1 (Subcohort 1A), 2 (Subcohort 1B), and 3 (Subcohort 1C) years, respectively after the first vaccination on Day 1. | Adult participants aged greater than or equal to (>=) 65 years received a single IM injection of placebo on Day 1. Participants were divided into revaccination subcohorts: 2A, 2B, and 2C. Participants further received revaccination with Ad26.RSV.preF 1*10^11 vp and RSV preF protein 150 mcg (protein mixture) at 1 (Subcohort 2A), 2 (Subcohort 2B), and 3 (Subcohort 2C) years, respectively after the first vaccination on Day 1. Participants in subcohorts 2A and 2B were additionally re-randomised in three groups at Year 2 and Year 3, respectively, to receive either Ad26.RSV.preF 1*10^11 vp alone, RSV preF protein 150 mcg alone or the Ad26.RSV.preF 1*10^11 vp and RSV preF protein 150 mcg (protein mixture). |
