Safety and Immune Response of the COVID 19 Vaccine in Patients with Inflammatory Bowel Disease


About this study

This will be a prospective study of patients with IBD at Mayo Clinic initially in Jacksonville with possible subsequent extension to other Mayo sites.  We will evaluate the immunogenicity of commercially available COVID-19 vaccines and compare vaccine response among the groups based on their immunosuppressive regimens.  We will divide the immunosuppressive regimens into presumed high vaccine responders Group A and presumed low vaccine responders Group B. We will also assess for adverse reactions to the vaccine and compare with the reported rates in the clinical trials that led to approval of these vaccines.
