• \(\bf Introduction\) To identify facilitators and barriers towards vaccination in general and specifically against pneumococci, influenza and SARS-CoV-2 in patients with rheumatic musculoskeletal diseases (RMD). \(\bf Methods\) Between February and April 2021, consecutive patients with RMD were asked to complete a structured questionnaire on general knowledge about vaccination, personal attitudes and perceived facilitators and barriers towards vaccination. General facilitators (n=12) and barriers (n=15) and more specific ones for vaccination against pneumococci, influenza and SARS-CoV-2 were assessed. Likert scales had four response options: from 1 (completely disagree) to 4 (completely agree). Patient and disease characteristics, their vaccination records and attitudes towards vaccination against SARS-CoV-2 were assessed. \(\bf Results\) 441 patients responded to the questionnaire. Knowledge about vaccination was decent in \(\geq\)70% of patients, but <10% of patients doubted its effectiveness. Statements on facilitators were generally more favourable than on barriers. Facilitators for SARS-CoV-2 vaccination were not different from vaccination in general. Societal and organisational facilitators were more often named than interpersonal or intrapersonal facilitators. Most patients indicated that recommendations of their healthcare professional would encourage them to be vaccinated - without preference for general practitioner or rheumatologists. There were more barriers towards SARS-CoV-2 vaccination than to vaccination in general. Intrapersonal issues were most frequently reported as a barrier. Statistically significant differences in response patterns to nearly all barriers between patients classified as definitely willing, probably willing and unwilling to receive SARS-CoV-2 vaccines were noted. \(\bf Discussion\) Facilitators towards vaccination were more important than barriers. Most barriers against vaccination were intrapersonal issues. Societal facilitators identified support strategies in that direction.
