Population-Level Study Provides Reassuring Data on the Risk of Kidney Disease Relapse After COVID-19 Vaccination
American Society of Nephrology (ASN)• In a population-level study of 1,105 adults with stable glomerular disease (a type of autoimmune kidney disease), a first dose of a COVID-19 vaccine was not associated with relapse risk; however, receiving a subsequent vaccine dose was associated with a 2-fold higher relative risk of relapse. • Importantly, the increase in absolute risk associated with vaccination was low (1–5% depending on type of glomerular disease), and most vaccine-associated disease flares were mild.
