Abstract
This narrative review summarizes current evidence on the risk of systemic autoimmune rheumatic disease (SARD) flare following coronavirus disease 2019 vaccination. The authors detail key studies in the literature employing diverse methodologies, including cross-sectional surveys, prospective and retrospective cohorts, case-crossover designs, self-controlled case series, and systematic reviews. Data are reassuring, suggesting that vaccination is unlikely to increase the risk of flares across a range of SARD. When postvaccination flares do occur, individuals with high disease activity and frequent flares at baseline may be at higher risk. Rheumatologists may consider discussing these findings with patients during collaborative conversations about risks and benefits of vaccination.
