Safety and Efficacy of the Coronavirus Disease 2019 Vaccine in Hemodialysis Patients

Study Overview
=================
Brief Summary
-----------------
It is unknown whether Coronavirus disease 2019 vaccines confer the same high level of protection in patients with kidney disease as reported for participants in recent trials, who were generally healthy. Objectives: To evaluate the safety and efficacy of Coronavirus disease 2019 vaccines in hemodialysis patients.

Detailed Description
-----------------
Given the vulnerability of people with chronic kidney disease to Coronavirus 2019 , leading nephrology societies such as the National Kidney Federation and the American Kidney Foundation have issued statements calling for prioritization of these patients for vaccination. It is unknown whether Coronavirus disease 2019 vaccines confer the same high level of protection in patients with kidney disease as reported for participants in recent trials, who were generally healthy. Objectives: Estimate the proportion of hemodialysis patients who present events supposedly attributed to vaccines and immunizations after having received a Coronavirus disease 2019 vaccine Determine the levels of Immunoglobulin G antibodies in patients who received a Coronavirus disease 2019vaccine between the time before the first dose, at 21 days, at 40 days and at 120 days after immunization. Methods Design: Multicenter, observational and analytical study of a prospective cohort of hemodialysis patients 18 years and older who received immunization with a Coronavirus disease 2019 vaccine in the Autonomous City of Buenos Aires in a vaccination plan. Analysis The proportion of patients with Adverse events presumably attributable to vaccination and immunization will be estimated with its 95% confidence interval. The immunoglobulin G titer for coronavirus type 2 causing severe acute respiratory syndrome will be compared using Generalized Estimating Equations models.
