A Study of an Ad26.RSV.PreF-based Regimen at the End of Shelf-life in Adults Aged 60 to 75 Years
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.
