Aim: People with rheumatic diseases (PRD) remain vulnerable in the era of the COVID‐19 pandemic. We formulated recommendations to meet the urgent need for a consensus for vaccination against SARS‐CoV‐2 in PRD.Methods: Systematic literature reviews were performed to evaluate: (a) outcomes in PRD with COVID‐19; (b) efficacy, immunogenicity and safety of COVID‐19 vaccination; and (c) published guidelines/recommendations for non‐live, non‐COVID‐19 vaccinations in PRD. Recommendations were formulated based on the evidence and expert opinion according to the Grading of Recommendations Assessment, Development and Evaluation methodology.Results: The consensus comprises 2 overarching principles and 7 recommendations. Vaccination against SARS‐CoV‐2 in PRD should be aligned with prevailing national policy and should be individualized through shared decision between the healthcare provider and patient. We strongly recommend that eligible PRD and household contacts be vaccinated against SARS‐CoV‐2. We conditionally recommended that the COVID‐19 vaccine be administered during quiescent disease if possible. Immunomodulatory drugs, other than rituximab, can be continued alongside vaccination. We conditionally recommend that the COVID‐19 vaccine be administered prior to commencing rituximab if possible. For patients on rituximab, the vaccine should be administered a minimum of 6 months after the last dose and/or 4 weeks prior to the next dose of rituximab. Post‐vaccination antibody titers against SARS‐CoV‐2 need not be measured. Any of the approved COVID‐19 vaccines may be used, with no particular preference.Conclusion: These recommendations provide guidance for COVID‐19 vaccination in PRD. Most recommendations in this consensus are conditional, reflecting a lack of evidence or low‐level evidence.

Studies of flares of autoimmune inflammatory rheumatic diseases (AIIRD) after COVID-19 mRNA vaccination are limited by small sample size, short follow up or at risk of selection bias. A national retrospective cohort study of consecutive AIIRD patients ≥12 years old, across 8 hospitals who received at least one dose of a COVID-19 mRNA vaccine. Patients were included from the date of 1st vaccine dose and censored at the time of flare or on the date of the clinic visit at least 3 months from cohort entry, whichever came first. Predictors of flare were determined by Cox proportional hazards analysis. 4627 patients (73% Chinese, 71% female) of median (IQR) age 61 (48, 70) years were included; 42% Rheumatoid arthritis, 14% Systemic lupus erythematosus and 11% Psoriatic arthritis. 47% were in remission, 41% low disease activity, 10% moderate disease activity and 1% in high disease activity. 18% patients flared, of which 11.7% were within the 3-month period of interest. 11.8% patients improved. Median (IQR) time-to-flare was 60 (30, 114) days. 25% flares were self-limiting, 61% mild-moderate and 14% severe. Older patients (53–65 years and >66 years) had a lower risk of flare [HR 0.6 (95% CI 0.5–0.8) and 0.7 (0.6–0.8) respectively]. Patients with inflammatory arthritis and with active disease had a higher risk of flare [HR 1.5 (1.2–2.0) and 1.4 (1.2–1.6), respectively]. Treatment with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), immunosuppression and prednisolone was also associated with an increased risk of flare [HR 1.5 (1.1–2), 1.2 (1.1–1.4) and 1.5 (1.2–1.8) for prednisolone ≤7.5 mg respectively]. There was a moderately high rate of AIIRD flares after mRNA vaccination but also improvement in several patients. Severe flares and hospitalisation were rare. Thus, vaccination remains safe and highly recommended.
