I had the Astra Zenecca vaccine on Monay. No issues at all, execept slightly tender spot at injection site which had gone by yesterday.
My wife ( who does not have AFIB) also had the jab and developed a very sore arm within hours followed by a high temp 38.5 c , which was controlled by paracetamol during Tuesday. The temp disappeared overnight Tuesday, but she still has the very sore arm this morning can't lift it up to shoulder height .
Not a medically trained virologist, but I am assuming that the reaction to the jab means that she would have had a bad reaction to Covid itself?? So very good she had the vaccine if that is the case!
The other lesson for those who have not yet had the vaccine- make sure if you are right handed you have the jab in the left arm, in case you too get the sore arm!
Best wishes.
