Doctors are starting to learn which vaccines patients with IBD may have lost response and protection to and which vaccines patients with IBD need a booster shot for. Jeanne Tung, M.D., discusses a recent study published in the Inflammatory Bowel Diseases Journal focusing on the hepatitis A vaccine and inflammatory bowel diseases. Hepatitis A is a virus passed through contaminated food or water supply and can cause severe vomiting, diarrhea, and liver inflammation.
The study, conducted in Korea, gave 491 patients two shots of the hepatitis A vaccine and measured how much of the hepatitis A vaccine was still in their body. At the end of the study, the results showed patients had a good response rate of 92-99%. The results did find that patients taking anti-TNF drugs, such as Remicade or Humira, had lower response rates than patients taking other medications. The response rate for patients taking anti-TNF drugs was 92%.
This study shows that patients with IBD who get the hepatitis A vaccine will generally be very well protected. It may be a good idea to get the hepatitis A vaccine before going on an anti-TNF drug.
