Has anyone had this? I had no side effects from my previous jabs apart from a sore arm. I had this booster at lunchtime today and currently had a very upset stomach (not sure if the jab or coincidence) and am worried about feeling rubbish tomorrow as I have a conference in the morning. From what I've read, it says any adverse side effects are usually between days 2 and 4.
If you've had it, and had side effects, when did they start, please?
