Objectives To identify potential predictors of COVID-19 vaccine hesitancy (C19-VH) in adults with immune-mediated inflammatory diseases (IMID). Methods A total of 1,000 IMID patients were enrolled in this web-based cross-sectional study. A standardised and self-administered survey was designed by members of the Brazilian Society of Rheumatology Steering Committee for Infectious and Endemic diseases and distributed to IMID patients spread across Brazil. Results Of the 908 (90.8%) respondents eligible for analysis, 744 (81.9%) were willing to get vaccinated against COVID-19. In our multivariable logistic regression model, concurrent malignancy, fibromyalgia, hydroxychloroquine use, and recent corticosteroid pulse therapy were independently associated with higher odds of C19-VH. The short duration of COVID-19 vaccine clinical trials was the main reason for C19-VH. Conclusion We identified novel characteristics potentially associated with C19-VH among adults with IMID. Greater awareness on the safety and efficacy of COVID-19 vaccines is needed for both IMID patients and attending physicians.
