Brief Summary:
This is a prospective cohort study aimed to evaluate short- and mid-term immune response after SARS-CoV-2 vaccination using Gam-COVID-Vac (Sputnik V) vaccine in dialysis patients compared to the control group (medical staff).
Detailed Description:
Background and aims: Patients receiving kidney replacement therapy with dialysis are at high risk of infection and death from COVID-19. There is a lack of evidence whether SARS-CoV-2 vaccination is effective in this immunocompromised group.
Study design: this is a prospective cohort study. Two cohorts will be included: dialysis patients and controls (medical staff), both vaccinated with Gam-COVID-Vac (Sputnik V) vaccine.
Blood samples will be collected at 28 days and 22 weeks after after the second SARS-CoV-2 vaccine dose administration.
The primary outcome is the level of SARS-CoV-2 IgG antibodies on day 28 after the second vaccination as compared to controls.
The secondary outcomes are: 1) the level of SARS-CoV-2 IgG antibodies on week 22 after the second vaccination; 2) T cell subtype immunity measured by SARS-CoV-2 interferon-γ release assays (IGRA) 28 days and 22 weeks after the second vaccination.
