I don't like having injections, but of course this is essential and a privilege to have it. I had the Pfizer, and speaking as a total wuss, it was hardly anything, a tiny scratch, not painful at all. Will have no qualms about having the second, whenever that may be.
That night my arm was a little tender, just avoided lying on that side. Next day all fine, and has been ever since.
Two weeks later OH had the AZ. He had more of a reaction that night. He was icy cold and could not stop extreme shivering, and had a weird headache. It was like a fever really. Next day he felt better, I made him sleep in the afternoon to catch up, and had some paracetamol. All fine since. Again he will happily have the 2nd, but will take paracetamol immediately if he feels any reaction.
We are both relatively healthy and I am not aware that we have ever had Covid, we have been keeping well away from everyone.
I feel relief that if I did get it now, I would hopefully not be so ill, and maybe would not have the risk of being taken to hospital.
