Brief Summary

Vaccination against SARS CoV-2 appears to be the best strategy today to control the COVID-19 pandemic. The first published studies with Pfizer, Moderna and Astra-Zeneca vaccines show very good vaccine protection in the general population and good short-term tolerance. The efficacy of these vaccines ranges from 62 to 95%, which is particularly remarkable, especially for mRNA vaccines. Nevertheless, these studies do not report the vaccine response in organ transplant patients. It is known that transplant patients have lower vaccine responses than immunocompetent patients due to some degree of immunosuppression. Therefore, the investigators are interested in evaluating the vaccine response of organ transplant recipients after vaccination against SARS- CoV-2. For non-responder patients, new strategies can be proposed: 3rd or 4th boost of vaccine or perfusion/injection of antiS monoclonal antibodies. These strategies must be evaluated.

Outcome Measures

Primary Outcomes (1)

  • Percentage of patients who develop a seroconversion for SARS Cov-2 anti Spike antibodies

    One month after the 2nd injection of the COVID-19 vaccine

Secondary Outcomes (5)

  • Compare the seroconversion between different vaccines

    At Month 3, Month 6, Month12 and Month 24 after the 2nd injection of the COVID-19 vaccine

  • Percentage of patients who develop a seroconversion for SARS Cov-2 anti Spike antibodies

    At Month 3, Month 6, Month12 and Month 24 after the 2nd injection of the COVID-19 vaccine and at Month 1 after the 3rd and 4th injection.

  • Describe the patients characteristics associated with seroconversion

    At Month 24 after the 2nd injection of the COVID-19 vaccine

  • Assess the tolerance of the 3rd and 4th doses of vaccine in transplant patients

    At the day of injection, Month 1, Month 2, Month 3, Month 6 and Month 12 post injection

  • Percentage of patients who develop a Seroconversion for SARS Cov-2 anti Spike and anti N antibodies after injection of monoclonal antibodies

    At Month 1, Week 6, Week 8, Month 3, Month 6 and Month 12 afin injection of monoclonal antibodies
