INTERVENTIONAL
Conditions
Summary
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.
