Don't be so sure Sillyoldfool I had 'real 'flu' and lost a week of my life. Yes it was awful. I had the 'flu jab and my reaction was not 'peanuts' I was ill for two whole months with fever, sweating, exhaustion, rashes....couldn't do anything, go anywhere, if I got out of bed I was sick and dizzy.
It is probably karma as I used to tell other people they couldn't possibly have such a reaction, and trivialise their experience. I know better now. There's just too much anecdotal evidence for all this to be coincidence, but of course it cannot be investigated by double blind trials, so it must be our imagination?
It's a bit like saying 'I cross the road every day and I've never been knocked over yet!' And yet people are....
