COVID-19 vaccine confidence in the post-vaccination era: Perceptions among adults with immune-mediated inflammatory diseases

OBJECTIVE: Assess the perceived protection afforded by a range of COVID-19 vaccines in immune-mediated inflammatory diseases patients previously vaccinated against SARS-CoV-2. STUDY DESIGN: Survey. METHODS: On-line cross-sectional survey aimed at evaluating the perceived protection (and its determinants) afforded by a range of COVID-19 vaccines among immune-mediated inflammatory diseases previously vaccinated for COVID-19. RESULTS: Out of 493 eligible respondents who lived in Brazil, 397 (80.5%) were confident that their primary vaccination series would protect them against severe COVID-19. In multivariate analysis, only overlapping immune-mediated inflammatory diseases remained (negatively) associated with the perception of protection. CONCLUSIONS: No influence was found between COVID-19 vaccine types and the perception of protection after initial vaccinations.
