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.\n\nObjectives:\n\n1. Estimate the proportion of hemodialysis patients who present events supposedly attributed to vaccines and immunizations after having received a Coronavirus disease 2019 vaccine\n2. 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.\n\nMethods 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.\n\nAnalysis The proportion of patients with Adverse events presumably attributable to vaccination and immunization will be estimated with its 95% confidence interval.
