Patients with celiac disease have an increased risk for severe influenza infection and they show less of a response to certain vaccine types. During the influenza A/H1N1/09 pandemic, we prospectively investigated pandemic vaccine responses in 14 pediatric patients with celiac disease and age-/sex-matched controls. All of the children with celiac disease reached protective antibody titers (≥40) and showed a geometric mean titer comparable with the control group (530 vs 573).
