LESS CoV-2: RECOVAC - Long Term Efficacy and Safety of COVID-19 (SARS-CoV-2) Vaccination in Kidney Disease Patients
Study Details
Study Description
Brief Summary
Rationale: COVID-19 is associated with severely increased morbidity and mortality in patients with chronic kidney disease stage G4-G5 and patients on dialysis or after kidney transplantation. Therefore, effective SARS-CoV-2 vaccination would be of great clinical importance in these patients. However, SARS-CoV-2 vaccination studies have excluded these patients so-far. Literature data indicate that vaccination may be less effective in these patient groups.
Objective: To assess the efficacy and safety of SARS-CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, patients on dialysis or after kidney transplantation during two years follow-up after vaccination.
Study design: prospective single center observational cohort study.
Study population:
-
all Dutch patients on dialysis with data registered in the Dutch Dialysis registry (RENINE)
-
all Dutch patients after kidney transplantation with data registered in the Dutch national kidney transplant registry (NOTR).
-
All Dutch patients with chronic kidney disease stage G4-G5 registered in the Santeon hospitals.
Intervention: After SARS-CoV-2 vaccination according to standard of care, blood will be drawn for antibody response measurements at day 28 and month 6 after 2nd vaccination at by mailer-based finger-prick in 3400 hemodialysis patients, 600 peritoneal dialysis patients, 4000 patients after kidney transplantation and 4000 patients with chronic kidney disease stage G4-G5. Patients who will undergo a 3rd SARS-CoV-2 vaccination via the national vaccination program for immunocompromised patients will be asked to carry out the mailer-based finger-prick 28 days after the 3rd SARS-CoV-2 vaccination, instead of the antibody measurement 6 months after the 2nd SARS-CoV-2 vaccination.
Main study parameters/endpoints:
The primary endpoint is efficacy of SARS-CoV-2 vaccination determined as:
- the incidence of COVID-19 after vaccination.
Secondary endpoints are
-
mortality
-
adverse events of specific interest according to (inter)national authorities in collaboration with LAREB
-
presence of HLA-antibodies in dialysis patients on the waiting list for a first kidney transplantation
-
acute rejection and graft failure in patients after kidney transplantation In a subset of patients additional secondary endpoints will be assessed
-
the antibody based immune response at 28 days after completion of SARS-CoV-2 vaccination.
-
the durability of antibody based immune response at 6 months compared to at 28 days after having received two subsequent SARS-CoV-2 vaccinations, in patients that have not received a 3rd SARS-CoV-2 vaccine.
-
the antibody based immune response at 28 days after having received the 3rd SARS-CoV-2 vaccination.
The incidence of these endpoints will be compared, if applicable, to those:
-
in the general population who are vaccinated
-
in patients on dialysis or after kidney transplant who are not vaccinated Within these patient groups endpoints will be compared between recipients of different vaccines.

- STUDY DESIGN
This is a prospective observational registry-based cohort study to evaluate the long-term efficacy and safety after SARS-CoV-2 vaccination on clinically important outcomes in patients with chronic kidney disease stage G4-G5, on dialysis or after kidney transplantation.
All participants will receive vaccination against COVID-19 via the national vaccination program and according to the manufacturer's instructions. To assess the immune response after vaccination, blood samples will be collected at 28 days after the 2nd SARS-CoV-2 vaccination, 28 days after the 3rd SARS-CoV-2 vaccination, and 6 months after the 2nd SARS-CoV-2 vaccination in patients who have not received a 3rd vaccination. In total a maximum of 1 ml blood will be drawn.
Data of the following cohorts will be analyzed in this study.
-
Patiens with chronic kidney disease stage G4-G5, data to be derived from the Santeon hospitals.
-
Patients on hemodialysis and peritoneal dialysis, data to be derived from the existing national registry RENINE
-
Kidney transplant recipients, data to be derived from the existing national registry NOTR
-
Patients on dialysis or after kidney transplantation with COVID-19 disease, data to be derived from the ERACODA database.
- METHODS
Main study parameter/endpoint:
The primary endpoints is the incidence of COVID-19 in a two years period after SARS-CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, on dialysis or after kidney transplantation.
Secondary study parameters/endpoints:
Safety in all patients:
-
Incidence of mortality
-
Incidence of adverse events of specific interest as defined by (inter)national authorities in collaboration with LAREB
-

The antibody response against the SARS-CoV-2 Receptor Binding Domain at 28 days after the final SARS-CoV-2 vaccination.
-
The antibody response against the SARS-CoV-2 Receptor Binding Domain at 28 days after the 3rd SARS-CoV-2 vaccination.
-
The durability of antibody based immune response against SARS-CoV-2 Receptor Binding Domain at 6 months compared to 28 days after completion of SARS-CoV-2 vaccination in patients who did not receive a 3rd SARS-CoV-2 vaccination.
Exploratory study parameters:
-
Vaccination coverage rates
-
Disease severity in patients who develop COVID-19, assessed as
-
Hospitalization
-
ICU admission
-
Mechanical ventilation
-
Mortality
-
The influence of vaccination on health-related quality of life by patient reported outcome measures (PROMs) in dialysis patients
-
SARS-CoV-2 genotype in patients with COVID-19
In a subgroup of participants:
-
To assess the level of SARS-CoV-2 Receptor Binding Domain antibody response after vaccination between patients with COVID-19 and without COVID-19 at:
-
28 days after the 2nd SARS-CoV-2 vaccination
-
28 days after the 3rd SARS-CoV-2 vaccination
-
6 months after the 2nd SARS-CoV-2 vaccination in patients who have not received a 3rd vaccine.
-
To assess change in behaviour towards measures against COVID-19 before and after vaccination
These data collected after SARS-CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, on dialysis and after a kidney transplantation will (if applicable data are available) be compared:
-
to those obtained in the general population
-
to those obtained in patients with chronic kidney disease stage G4-G5, on dialysis or with a kidney transplant who are not vaccinated
-
according to the type of vaccination received These comparisons will allow us to analyze whether SARS-CoV-2 vaccination offers efficacy to prevent COVID-19 and sufficient safety in patients with chronic kidney disease stage G4-G5, dialysis and kidney transplant patients when compared to non-vaccinated patients with chronic kidney disease stage G4-G5, dialysis and kidney transplant patients, whether the efficacy is similar as in the general population, and whether there are differences in the risk-benefit ratio between the various vaccines.
