You’ve also sourced a 2021 study there.
This is from 2023 :
Is Vaccination Against COVID-19 Associated With Inflammatory Bowel Disease Flare? Self-Controlled Case Series Analysis Using the UK CPRDTimothy R Card et al. Am J Gastroenterol.2023.
Discussion: Vaccination against COVID-19 was not associated with IBD flares regardless of prior COVID-19 infection and whether messenger RNA or DNA vaccines were used.

However I have read an association between Covid infection itself/Crohn’s disease.
Therefore you are posting a 2021 source without context, without proper analysis which could concern people about taking the vaccine. This is why consensus science is far safer then : unqualified people making assumptions based on a paper published 3 years ago.
