A Phase 4 interventional study of RSVPreF3 vaccination in Vaccination, Respiratory Syncytial Virus (RSV) and Lung Transplant Recipient, sponsored by Seoul National University Hospital. Recruiting at 1 site in South Korea. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2026-10-26.
Sponsored by Seoul National University Hospital · Phase 4, Interventional, and Prevention
The purpose of this study is to compare the immunogenicity and safety of respiratory syncytial virus (RSV) vaccination between lung transplant recipients and immunocompetent adults and to provide evidence to guide RSV vaccination in lung transplant recipients.
Seoul National University Hospital is the lead sponsor of 1,898 studies on the registry; 274 are open to participants now.
Of its 12 completed or terminated interventional studies of FDA-regulated products, 2 (17%) have results posted.

Plan to share: No — We are not planning to share IPDs publically, but de-identified individual participant data for all outcome measures could be shared with other researchers under their request.
