Hello Wendy!
I have yet to meet anyone who has had a flu jab and not been ill afterwards. My father and his wife have jabs because of their age and they are ill every year. My brother is in his 40s and he is obliged to have one every year by his employer. Every time he is knocked up badly for about two weeks afterwards and he says that most of his colleagues are too. It's also the case at a day centre I visit frequently. I see the clients there have jabs, and then they are bad for a week or so - we predict it before they go the the doctor!
At the risk of upsetting the medical fraternity, I have frequently said that I will just catch flu naturally if that's the case. I see these people ill every year and I stay well. I will add that I developed real influenza (not a heavy cold) when I was 12 and I was very ill for the best part of a month. Once I'd recovered, the doctor said I may well never have a cold or flu again - and I don't think I ever have. I just get a tickly nose for a few hours and then it is gone, although my wife goes down with bad colds every year.
Perhaps it's not very helpful Wendy - and some may say irresponsible- but I would say just avoid these damn jabs. It's up to you. Its all very well promoting innoculations to fight epidemics etc, but they just seem to make most people ill anyway.
