Sensitive Stomach and Covid Vaccine

Hi,

I been getting better on my digestive sensitivities by doing a LOW FODMAP diet. I was eating too much avocado and high FODMAP foods for almost a year. With the low acid or sensitive stomach, that really was tough. I was paying attention on the healthy diet but not realizing it could still affect the sensitive stomach.

My concern right now is on the COVID Vaccine. Anybody getting a COVID vaccine with sensitive stomach?
Does it affect anybody. Just want some ideas. Thank you.
