I am hoping to get something out this evening but I have been laid low the last couple of days after receiving my vaccine.
Same happened to me. Had my AZ jab the Saturday before last. Within an hour I sensed that I was having a reaction, and for the next few days I had bouts of dizziness, could feel my heart racing, had sweats and some aches and pains. None of the symptoms lasted more than a few minutes and they lessened as the days passed, but it was Thursday before I was feeling back to normal. Incidentally, my brother-in-law (who was until recently Professor of Pharmacology & Therapeutics at L'pool Uni, and understands this) tells me that there is some data to show that the AZ vaccine is more likely to give side-effects compared to the Pfizer. On the plus side, he said that there is also some research presenting that suggests that people who suffer a reaction to the vaccine are more likely to have come into contact with the virus already (but been asymptomatic) and developed antibodies.
Not posting this to get into a debate, I fully support having the vaccine.
Wishing you a full and speedy recovery, Bill.
