Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Vaccination against SARS-Cov2 is a necessity for haemodialysis patients because difficulties to maintain a self-isolation (leading to a higher contamination than general population) and an increase of mortality in case of contamination (more than 20% of mortality in this population). However, vaccine efficiency is known to be decreased in haemodialysis patients. This lead critical the rapid description of immunogenicity of anti SARS-Cov2 vaccine in haemodialysis patients.

The aim of this study is to describe the immunogenicity of the BTN162b2 SARS-Cov2 vaccine in haemodialysis patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

All haemodialysed patients with a medical prescription of BTN162b2 mRNA Cov-19 vaccine

Serological response is defined by a 4 fold increase of IgG anti-spike protein of SARS-Cov2 between Day 0 (before vaccination) and after complete vaccination (evaluated at Day 7 - 14 post-boost).

Evaluation of the immunogenicity of the vaccine in haemodialysis patients

Intervention Type BIOLOGICAL

The immunogenicity of the vaccine will be evaluated at the peak of vaccine response (Day 7 - Day 14 after the second dose) and 6 and 12 months post vaccination, by the evaluation of humoral IgG anti-spike protein response (seroconversion rate, absolute antibody titers, affinity of antibody) and cellular anti SARS-Cov2 response (number, activation capacity, production of interferon gamma of CD4 and CD8 anti sars cov2 specific T cells)
