Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The overall objective of this proposal is to evaluate the safety and immunogenicity of a COVID-19 vaccine in patients with Inflammatory Bowel Disease (IBD). This will help determine if immunosuppressive regimens impact COVID-19 vaccine response. The investigators will determine if certain groups may need more doses of a vaccine, with future adjuvanted vaccines or require a booster to maintain immunity. 260 participants with IBD and scheduled to get a COVID-19 vaccine will be recruited and can expect to be on study for 18 months.
