Children with chronic health conditions, including IBD, are at especially high risk for influenza infection and resulting complications. The Crohn’s & Colitis Foundation’s Top 10 Quality Process Indicators for IBD and American College of Gastroenterology’s clinical guidelines for preventative health maintenance recommend that IBD patients should receive annual influenza vaccination. The aims of this study were to evaluate influenza vaccination coverage over time and identify predictors of flu vaccination in pediatric IBD and non-IBD patients.
