Shingrix in Renal Transplant Recipients
Safety and Immunogenicity of Shingrix in Renal Transplant Recipients
Source: ClinicalTrials.gov · Last updated 8 Apr 2026
Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- 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 Known allergy to any component of the Shingrix vaccine Receipt of investigational drugs within 30 days prior to enrollment or planned use during the study Receipt of non-live vaccines within 2 weeks prior to any Shingrix dose or planned within 30 days after vaccination Receipt of live vaccines within 4 weeks prior to any Shingrix dose or planned within 30 days after vaccination Pregnant or breastfeeding Planned or prior multi-organ transplantation Residence or travel distance greater than 2 hours from the study site, which would interfere with study visits or timely processing of blood samples
Who the study is looking for
- 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
Criteria the registry did not label
- Study Population:
- Adults with chronic kidney failure who are listed for kidney transplantation at participating transplant centers.
Age in the registry: 18 years to 70 years · Sex: All · Does not accept healthy volunteers
