- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 64 Years
- Healthy Volunteers: t

Study Arms:
- Control Group (Type: OTHER): A group of 20 healthy individuals without IBD, other chronic diseases, or immunosuppressive therapy will be enrolled. All healthy individuals will receive standard dose influenza vaccine SDIV.
- Vedolizumab Group + standard dose influenza vaccine (SDIV) (Type: OTHER): A group of 20 patients who are currently on vedolizumab. All individuals in this group will receive SDIV
- High dose influenza vaccine (HDIV) (Type: OTHER): This arm will be a double blind randomized controlled trial of High dose influenza vaccine (HDIV) for IBD patients on TNF monotherapy.~40 patients will be enrolled and randomized in a 5:3 fashion to HDIV or SDIV. Randomization will generated by a random number generator and investigator will be blinded to randomization scheme.
- Standard dose influenza vaccine (SDIV) (Type: OTHER): This arm will be a double blind randomized controlled trial of standard dose influenza vaccine (SDIV) for IBD patients on TNF monotherapy.~40 patients will be enrolled and randomized in a 5:3 fashion to HDIV or SDIV. Randomization will generated by a random number generator and investigator will be blinded to randomization scheme.

Based on this trial design, predict the completion outcome and termination type (if applicable).
