when I worked in the hospital around 2001 we were
told all healthcare workers had to have the flu shot.
Not knowing any better I did.
2 days later I went home sick with flu like symptoms
I was sick with the chills fever cough cold etc...
for a week. since then I have not had a shot and have
not had the flu.

a young vietnamese man kept warning me
don't get the needle you don't know whats in it.
I thought he was the crazy one.
