Immunological Follow-up After SARS CoV2 Vaccination in Kidney Transplant Recipients

University Hospital, Strasbourg, France37 enrolled

Overview

The investigators goal is to assess the vaccine response of kidney transplant patients following vaccination against SARS-CoV-2. The study population will be derived from cohorts of kidney transplant patients who have been transplanted for more than 3 months and have no contraindications to vaccination. These patients will be vaccinated as part of routine care with a CoV-2 SARS vaccine licensed in France. In this cohort, the investigators wish to study the post-vaccination humoral response by assaying neutralizing antibodies against SARS CoV-2 and the specific cellular response of SARS Cov-2 by quantiferon and in vitro lymphocyte stimulation assays.
