I should point out, I am not a medical person, so what I am posting here is just my own personal opinion.
I am 80 and I am taking up my surgery’s offer of the Covid vaccine.
Years ago, a doctor I trusted implicitly advised me to take advantage of any vaccines I was offered. This was all quite new then.
I did have a bit of an unpleasant reaction to my Covid jab last year. I felt as though I had flu, and the aches and pains weren’t pleasant. When I told my doctor, she said that if I had reacted in that way to just the jab, the real thing without the jab could make me very ill.
I had a similar adverse reaction to the Rabies jab years ago, which I had to have to do the job I was doing. The doctor I saw at the time said the same thing.
So, I shall be having everything they throw at me, and be very grateful to have the opportunity.
Each to his/her own obviously! This is just my take on it.
