Disease Flare and Reactogenicity in Patients With Rheumatic and Musculoskeletal Diseases Following Two‐Dose SARS–CoV‐2 Messenger RNA Vaccination

Objective To evaluate disease flare and postvaccination reactions (reactogenicity) in patients with rheumatic and musculoskeletal diseases (RMDs) following 2‐dose SARS–CoV‐2 messenger RNA (mRNA) vaccination. Methods RMD patients (n = 1,377) who received 2‐dose SARS–CoV‐2 mRNA vaccination between Dec...

Description
Summary:Objective To evaluate disease flare and postvaccination reactions (reactogenicity) in patients with rheumatic and musculoskeletal diseases (RMDs) following 2‐dose SARS–CoV‐2 messenger RNA (mRNA) vaccination. Methods RMD patients (n = 1,377) who received 2‐dose SARS–CoV‐2 mRNA vaccination between December 16, 2020 and April 15, 2021 completed questionnaires detailing local and systemic reactions experienced within 7 days of each vaccine dose (dose 1 and dose 2), and 1 month after dose 2, detailing any flares of RMD. Associations between demographic/clinical characteristics and flares requiring treatment were evaluated using modified Poisson regression. Results Among the patients, 11% reported flares requiring treatment; there were no reports of severe flares. Flares were associated with prior SARS–CoV‐2 infection (incidence rate ratio [IRR] 2.09, P = 0.02), flares in the 6 months preceding vaccination (IRR 2.36, P
