Background: In the second year of the COVID-19 pandemic, highly effective and safe vaccines became available. Since patients with rheumatic diseases show increased susceptibility to infections and typical medications raise the risk of severe COVID-19, high vaccination coverage is of significant importance to these patients.
Methods: Consecutive patients with different rheumatic diseases were asked for their vaccination status regarding COVID-19, influenza and Streptococcus pneumoniae during their routine consultations. Any reported vaccination was validated with their personal vaccination card and/or by reviewing the CovPass smartphone app. Reasons for not having a COVID-19 vaccination were documented.
Results: A total of 201 patients (mean age 62.3 ± 14.1 years) were included, the majority of them (44.3%) with rheumatoid arthritis, followed by spondyloarthritis (27.4%) and connective tissue diseases (21.4%). Vaccination coverage for SARS-CoV-2 was 80.1%; 85.6% got at least the first vaccination shot. Both valid influenza and pneumococcus coverage were associated with a higher probability of SARS-CoV-2 vaccination (odds ratio (OR) 6.243, 95% confidence interval (CI) 2.637-14.783, p < 0.0001 and OR 6.372, 95% CI 2.105-19.282, p = 0.0003, respectively). The main reason for a missing SARS-CoV-2 vaccination (70%) was being sceptical about the vaccine itself (i.e., the subjective impression that the vaccine was not properly tested and fear of unwanted side effects).
Conclusions: Vaccination coverage against SARS-CoV-2 is high in patients with rheumatic diseases. Nevertheless, there are unmet needs regarding vaccination education to further increase vaccination rates.
