Had my first dose today, a bit late due to having bought and then moved into a house 2 weeks ago and not had the time to book it in.
I had an, er, interesting experience. Ten minutes after the jab, while still in the post-jab waiting room, I suddenly felt hot and sick, and before I know it, I've passed out and fallen off the chair. Had a strange semi-conscious experience while out of it, then next thing I know I'm being woken by what I believe were ambulance staff. Before I've even come around properly they've got my legs up on a chair and are checking my blood pressure. Then my other half, who was jabbed at the same time as me, appeared.
No fear of needles or anything, just fainted almost out of nowhere 10 mins later! I guess this is why you have to wait 15 minutes after!
