Individuals with Inflammatory Bowel Disease (IBD) are more susceptible to experiencing severe complications of COVID-19 if infected. Nevertheless, sub-optimal immunization rates have been reported among these patients. Our study aims to assess COVID-19 VH among a global population of patients with IBD and to investigate the role of healthcare professionals, particularly gastroenterologists, in promoting immunization. Twenty-six studies were systematically selected from scientific articles in the MEDLINE/PubMed, WoK, and Scopus databases from January 1, 2020, to September 15, 2023. The pooled prevalence of COVID-19 VH was 27.2% (95%CI = 20.6-34.2%). A significant relationship was evidenced between COVID-19 vaccine compliance and receiving advice from gastroenterologists or healthcare providers (OR = 2.77; 95%CI = 1.79-4.30). By leveraging their knowledge of IBD, familiarity with patient histories, and trusted patient-doctor relationships, gastroenterologists are pivotal in promoting vaccination. This patient-centered care is crucial in increasing vaccine acceptance among individuals with IBD, contributing to better public health outcomes.
