Brief Summary
Clinical studies indicate a decrease in vaccine efficacy in certain immunocompromised populations (kidney transplant recipients, patients undergoing chemotherapy). It was recently reported that only 18% to 49% of heart transplant recipients developed antibodies after 2 doses of BNT162b2 vaccine. Following the published results, it is currently recommended to use 3 doses in organ transplant recipients who have not contracted COVID-19 and 2 doses in those who have been infected. The effectiveness of this strategy is not yet sufficiently evaluated in heart transplant recipients. Moreover, the factors associated with the humoral and cellular response, the kinetics and durability of the humoral response, the occurrence of the cellular immune response and the tolerance of the vaccine are not well known in this population. To provide answers to these different questions, we set ourselves the objective of evaluating the humoral and cellular response to messenger RNA (mRNA) vaccines in heart transplant recipients followed at Bichat Hospital.

Study Arms (1)
Heart transplant recipients
Heart transplant recipients followed at Bichat Hospital and who were offered vaccination against SARS-CoV-2, regardless of whether they agreed to be vaccinated or not.
Interventions
A blood of a sample of 2 x 7 mL will be collected for the analysis of the anti-SARS-CoV-2 T-cell response during a scheduled check-up as part of their routine follow-up
Patients who have received SARS-CoV-2 vaccination will be asked to complete the Vaccine tolerance questionnaire
For heart transplant recipients who were offered vaccination against SARS-CoV-2 medical records will be reviewed retrospectively.
Eligibility Criteria
Heart transplant recipients followed at Bichat Hospital and who were offered vaccination against SARS-CoV-2, regardless of whether they agreed to be vaccinated or not.
You may qualify if:
