Summary

The SARS-CoV-2 identified in China in January 2020 is the cause of an unprecedented pandemic. The SARS-CoV-2 and each viral variant are responsible of a respiratory infectious disease, which can be asymptomatic. Nevertheless, a part of infected patients will experiment serious forms associated with a high mortality rate. Most serious forms present with lymphopenia and a functional exhaustion of speicifci T lymphocytes. Several studies showed that these quantitative and qualitative lymphocyte abnormalities are associated with unfavourable patients' outcome. The investigators hypothesized that the use of anti-viral T lymphocytes from convalescent COVID 19 donors could be helpful to improve the prognosis of COVID-19 serious forms. This study aims to demonstrate the feasibility of setting up a biobank that could allow the preservation and production of a cellular immunotherapy specific to SARS-CoV-2.

Generation of a biobank allowing the cryopreservation of leucocytes from COVID19 convalescent donors

The investigators aim to demonstrate that it is possible to implement a biobank of leucocytes from convalescent donors that could be used as raw material to generate anti-SARS COV-2 viral specific T cells. The protocol will be explained during hospitalisation for each donor. If they agree, they will be included before they leave hospital. Few weeks later, if they have no exclusion criteria, they will consult in the hemapheresis department of the Nancy University hospital. After medical exams, a whole blood bag and blood samples will be taken with the aim to establish a bank of cryopreserved human leucocytes as a raw material for the generation of a T-Lymphocyte immunotherapy.
