  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Adults aged 19 years or older who voluntarily provide written informed consent to participate in the study
  • Recipients of a lung transplant who are receiving immunosuppressive therapy to prevent allograft rejection.
  • Adults aged 60 years or older who voluntarily provide written informed consent to participate in the study.

Who cannot join

  • Participants will be excluded if they meet any of the following criteria
  • Previous receipt of any RSV vaccine.
  • RSV infection diagnosed within the past 12 months.
  • History of a severe allergic reaction to any component of the RSV vaccine.
  • Moderate or severe acute illness at the time of screening.
  • Pregnancy, planned pregnancy, or breastfeeding.
  • Any underlying medical condition for which intramuscular injection is contraindicated.

About this study

Official title: Analysis of Vaccine-induced Immune Responses and Optimization of Protective Immunity Against Respiratory Syncytial Virus in Lung Transplant Recipients

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.

Read the detailed description
  • Lung transplant recipients and immunocompetent adults who are willing to receive a respiratory syncytial virus (RSV) vaccine will be recruited at the study hospital.
  • Participants will receive a single intramuscular dose of the RSV vaccine (RSVPreF3, Arexvy®)
  • Participants will be contacted by telephone on Day 7 and at the Day 30 follow-up visit after vaccination to assess adverse events.
  • Immunogenicity will be evaluated before vaccination and at 1 month and 12 months after vaccination, and safety will be monitored throughout the study period.
  • Changes in immune responses from pre-vaccination levels will be compared between lung transplant recipients and immunocompetent adults.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing RSVPreF3 vaccination in people with Vaccination and Respiratory Syncytial Virus (RSV), run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 26 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Chan Mi Lee, M.D., PhD. (82-2-2072-1473, heaven229@naver.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Humoral immune response (neutralizing antibody) (time frame: 1 month after vaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07895394, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2026.
