Shingrix in Renal Transplant Recipients

Plain-language summary
The goal of this clinical trial is to learn how well the shingles vaccine (Shingrix) works and how safe it is in adults with kidney failure who are waiting for a kidney transplant, including those who later receive a transplant. The study also aims to find out whether giving an extra (third) dose of the vaccine after transplant improves protection.
The main questions it aims to answer are:
How strong is the body's immune response to the vaccine at different time points (about 1 month, 2 years, and 3 years after vaccination) in people waiting for a kidney transplant?
Does a third dose of the vaccine after transplant improve the immune response compared to not receiving a third dose?
How long does protection from the vaccine last before and after transplant?
How safe is the vaccine in this group, including whether it affects transplant-related immune markers?
Researchers will compare people who receive a third dose of the vaccine after transplant to those who do not receive a third dose, as well as to results from similar groups studied in the past, to see if the extra dose improves immune protection.
Participants will:
Be screened to see if they can take part in the study Attend about 3 to 6 study visits over approximately 30 to 37 months Receive two doses of the shingles vaccine if they have not already been vaccinated, or complete study assessments if they were vaccinated before joining
If they receive a kidney transplant during the study, be randomly assigned (by chance) to receive either a third dose of the vaccine or no additional dose
Complete questionnaires, have physical exams if needed, and provide blood (and urine, if applicable) samples at study visits
Take part in follow-up visits to check immune response and safety, with the option to allow samples to be stored for future research
Shingrix is approved for adults aged 50 and older and for younger adults with weakened immune systems. However, giving a third dose after a kidney transplant is not standard practice and is being studied in this trial.

Study Population:
Adults with chronic kidney failure who are listed for kidney transplantation at participating transplant centers.
Inclusion Criteria:
Age 18 to 70 years Able and willing to provide written informed consent Currently on the waiting list for kidney transplantation at a participating institution, with anticipated transplantation occurring between \>3 and 24 months after the first dose of Shingrix
Either:
Eligible to receive Shingrix at study entry per CDC-recommended schedule, or Previously completed the Shingrix vaccination series within 3 to 24 months prior to study entry Female participants of non-childbearing potential (e.g., tubal ligation, hysterectomy, ovariectomy, or post-menopausal ≥12 months)
Female participants of childbearing potential must:
Use adequate contraception for at least 30 days prior to vaccination Have a negative pregnancy test on the day of each vaccination Agree to continue adequate contraception during the study and for 2 months after completing the vaccination series Be considered by the investigator likely to comply with study requirements
Exclusion Criteria:
Active immunosuppressive or immunodeficient condition (e.g., malignancy, HIV infection) or receipt of immunosuppressive therapy within 3 months prior to planned vaccination that, in the investigator's opinion, may interfere with vaccine response History of herpes zoster (shingles) within the past 3 years Receipt of varicella vaccine within 3 years prior to study entry …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
