I've had x2 Pfizer jabs and as others have said, first one no problems apart from slightly sore arm in the evening and next day. Second one affected me for 3-4 days. Felt hot (temp was Ok though), tight gripping headache, nausea, fatigue and generally hung over feeling. Having said that, it appears that I was the only one in my work group of 10 or so who did have any side effects.
Mrs TS has had the first one this week with no problems, will see how the second one goes in a couple of weeks or so.
