Attitudes Among Pediatric Gastroenterologists Toward Vaccination Based on an Anonymous Online Survey

Background: Children with inflammatory bowel disease (IBD) are at heightened risk for vaccine-preventable infections because of underlying immune dysregulation and long-term immunosuppressive therapy. Despite published guidelines affirming vaccine safety, real-world coverage remains suboptimal. It is a pilot, single-country survey designed to explore baseline knowledge and practices regarding vaccination in paediatric IBD within a specific local healthcare context. Objective: The objective of this study is to evaluate the knowledge, attitudes, and practices of paediatric gastroenterologists (PGs) regarding the immunisation of children with IBD. Methods: We conducted an exploratory pilot, cross-sectional survey of paediatric gastroenterologists in Russia, focusing on immunisation knowledge and practical barriers in routine care. A cross-sectional, anonymous online survey was distributed to PGs nationwide between January 2022 and April 2022. The online questionnaire explored demographic characteristics, awareness of international recommendations, perceptions of vaccine safety at various disease and treatment stages, and routine vaccination practices. Responses were analysed with non-parametric statistics (α = 0.05). In a parallel prospective cohort, the vaccination certificates of 98 paediatric IBD patients (January 2022–April 2023) were audited to quantify real-world coverage. Results: Fifty-one PGs completed the survey. Forty-one per cent agreed that vaccines do not provoke IBD flares, while 17.6% considered live vaccines acceptable during immunosuppressive remission. Nearly one-third (32%) did not personally oversee immunisation, and 18% occasionally discouraged vaccination during therapy. Only 35.3% deemed baseline serology essential before starting immunosuppression; 46.5% supported antibody checks immediately prior to vaccination. The certificate audit revealed a full schedule completion rate of 66.3% for measles–mumps–rubella and 74.2% for hepatitis B, contrasting with parental reports of 82.3% complete coverage. Conclusions: Knowledge gaps, limited guideline awareness, and parental concerns contribute to suboptimal vaccination of paediatric IBD patients. Targeted educational initiatives, clearer shared-care pathways, and routine certificate audits are needed to close the coverage gap and reduce infection-related morbidity. Findings are hypothesis-generating and reflect local practice; as a pilot study, results should be interpreted with caution and may not generalise beyond similar settings.
