I had Pfizer vaccine yesterday and while I was sat in the 15 min wait my heart started pounding and felt really hot and dizzy. I almost told someone but didn’t want to make a fuss and then it settled down and now I’m totally fine! Just wondered if it’s a normal side effect...from memory I had a similar reaction when I had the flu jab I just felt really dizzy and fast heart but then was fine so maybe my body just objecting to being jabbed!
