Clinical Trial Summary

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.

Intervention

Other:
• Study of the synthesis of antibodies directed against SARS
Between 5 mL and 45 mL of additional blood will be collected to study the synthesis of antibodies against CoV-2 SARS and to investigate whether specialised immune cells also show an effective response against the virus.
