Study Description

The study is a pragmatic, registry-based, open-label, individually randomized trial. The Danish nationwide administrative health registries will be used for data collection including baseline information, follow-up data, and safety monitoring. The study aims to randomize 130,000 participants. Participants will be individually randomized 1:1 to receive either a bivalent RSV prefusion F vaccine (RSV vaccine) or no RSV vaccine. The trial is designed to assess the vaccine effectiveness of the RSV vaccine vs. no RSV vaccine on RSV-related and all-cause cardio-respiratory outcomes.
