Brief Summary
The goal of this retrospective study is to evaluate the proportion of seroconversion after 2 doses mRNA anti-SARS-CoV2 vaccination in a cohort of high risk liver transplanted patients. Seroprevalence is a secondary objective in order to identify seronegative patients with a history of COVID-19 (ie who lost antibodies) and seropositive patients with no history of COVID-19. The hypothesis is that the degree of immunosuppression is determinant on the seroconversion rate and therefore, although at higher risk of severe forms of COVID-19, liver transplanted patients have a lower chance of being protected after vaccination. Seroconversion rate in previously seronegative and with no history of COVID-19 liver transplanted patients is the main evaluation criteria. The factors associated with the absence of seroconversion will be identified as a potential tool to better adapt the vaccination strategy in this population. The rate of seroconversion after the 1st dose will also be evaluated. Safety of the 1st and 2nd injection will be reported as well as their value to predict seroconversion. A control group of patients listed for transplantation will also be included both in the seroprevalence and the seroconversion analysis. Persistance of the antibodies in long-term after transplantation and after transplantation for the patients who have been vaccinated before transplantation will also be reported.
