March 16, 2013 updated by: Suk-Kyun Yang, Asan Medical Center

Immunogenicity of Hepatitis A Vaccine in Patients With Inflammatory Bowel Disease

The purpose of this study is to measure the immune response in 18-40 year old IBD patients after receiving the hepatitis A vaccine.

Detailed Description

The spread of hepatitis A has prompted the need for vaccination against this virus. It is uncertain that IBD patients can achieve a truly protective response after vaccination. The efficacy and safety of hepatitis A vaccination have not been evaluated in this population of patients. We would like to estimate the efficacy and safety of vaccination against hepatitis A in patients with IBD.
