Response of Haemodialysis Patients to BNT162b2 mRNA Cov-19 Vaccine
An observational study of COVID-19 Vaccines and Hemodialysis Complication, run by Hospices Civils de Lyon at 2 sites in France.
Trial summary
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).

About this study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Evaluation of the immunogenicity of the vaccine in haemodialysis patientsBiological
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)
| Study group | Role | What they receive |
|---|---|---|
| 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). Receives: Biological: Evaluation of the immunogenicity of the vaccine in haemodialysis patients |
What is being measured
The primary outcome is the main question the study is designed to answer.
Seroconversion rate after vaccination with BTN162b2 mRNA cov-19 vaccine
IgG anti SARS-Cov2 spike protein will be evaluated by ELISA at Day 0 (at the initiation of vaccination) anti Day 7 - Day 14 after the second dose (peak of response).
The seroconversion is defined by an 4 fold increase of IgG anti SARS-Cov2 spike protein titer between Day 0 and Day 7 - Day 14 after second dose.
Measured: The seroconversion rate is evaluated at Day 7-Day 14 after the second dose.

Primary outcome
Seroconversion rate after vaccination with BTN162b2 mRNA cov-19 vaccine
Time frame: The seroconversion rate is evaluated at Day 7-Day 14 after the second dose.
IgG anti SARS-Cov2 spike protein will be evaluated by ELISA at Day 0 (at the initiation of vaccination) anti Day 7 - Day 14 after the second dose (peak of response). The seroconversion is defined by an 4 fold increase of IgG anti SARS-Cov2 spike protein titer between Day 0 and Day 7 - Day 14 after second dose.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Seroconversion rate after vaccination with BTN162b2 mRNA cov-19 vaccine (time frame: The seroconversion rate is evaluated at Day 7-Day 14 after the second dose.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2022; AzTrials last refreshed its copy on 8 Nov 2026.
