I had my vaccine yesterday. Had the Pfizer vaccine. Was told all about possible side effects by the person doing the injection, plus given a leaflet which listed them all. It was all very open and clear that the vaccine, like all vaccines, can cause side effects.
Today I have a pretty sore achy arm and a headache, but nothing that painkillers can't sort.
Dh's colleague and wife had their Oxford vaccine on Monday. Both felt achy, tired and unwell. The man was ill enough not to be able to work. But by the evening he was feeling better and both are perfectly fine today.
Everyone else I know who have had the vaccine have had nothing worse than a sore arm. That's with both vaccines.
I actually read beforehand that the vaccines can cause unpleasant side effects short term so was able to manage my workload around it. I got everything that definitely had to be done out of the way before the vaccine, leaving today and tomorrow less of an issue. I have plenty to do, but all stuff that could have been delayed. As it is I'm fine to work, just have to rest my arm a bit very so often - luckily not my dominant arm.
It seems unfortunate that so many people within a limited number, in one work place, are all so badly effected. It may well be worth reporting as could be linked to one specific batch perhaps.
