Health authorities strongly recommend routine annual influenza vaccination (IV) with trivalente inactivated influenza vaccine for chronic diseases and immunosuppresed patients. Even though a great deal of inflammatory bowel disease (IBD) patients are included in this recommendation, European experiences show low rates of seasonal influenza vaccination uptake in this population.


Patients attended in our IBD Unit during influenza vaccination season 2012–2013 were invited to participate in this study. They were asked about their knowledge of this health advice, their personal opinions and their adherence to this recommendation. Afterwards, an intervention strategy took place performing an educational session by specialized nursing in order to higlight the benefits of influenza vaccination in IBD patients on inmunosuppresant or biological therapy. At the end of influenza season we checked the IV uptake in these IBD patients.


100 IBD patients were included: 76 had Crohn's disease and 24 ulcerative colitis. 28 were on anti tumour necrosis factor drugs, 57 on inmunosuppressive therapy and 15 on both.

22% patients had received routine annual influenza vaccination, 32% were not aware of the need for vaccination and had never received it and 8% had opted not to receive this vaccine.

After performing an education session by an specialized IBD nurse, we confirmed an important increase in influenza vaccination from 45% in season 2011–2012 to 72% in season 2012–2013, being significant (p = 0.01) in Crohn's disease patients, with no differences related to age, sex or inmunosuppresive therapy.


Nowadays seasonal influenza vaccination uptake is low in IBD patients on inmunosuppresive or biological therapy.

Interventional strategies by IBD nurses can improve the adherence to influenza vaccination uptake in these patients.
