💬In plain words
What the trial is, and whether it could suit you
The goal of this clinical trial is to compare responses to Varicella Zoster vaccination between transplant patients on different medication regimens, and their healthy co-habitants. The main questions it aims to answer are:
1. Are there differences in vaccination immunological responses in transplant patients on different immunosuppression regimens?
2. Are there differences in vaccination immunological responses between transplant patients and their healthy co-habitants? Participants will all receive a 2-dose course of SHINGRIX recombinant Zoster vaccination, and have immunological responses measured and compared at 5 timepoints between 1 week to 1 year post-vaccination.
