Work does free vacinations each year, the 1st year I rocked up to get my jab, filled out the questionairre and was told sorry, go away.
31 years ago I had an allergic reaction to wet choocks feathers when helping friends on their farm pluck feathers (swelled up like I had the mumps, eye's closed over, started to have breathing difficulties). Since that time I have been exposed to wet feathers in a sleeping bag, regullary eat eggs etc. etc. and their has never been another problem, didn't matter, they wern't willing to give me the jab.
I spoke to my doctor about a month ago, he says another company has nearly finished developing/testing a fully synthetic flu vacine that won't be an issue for me, should be out sometime mid winter - summer, I think I might wait till next winter to see if there is any other side effects once it hits the streets.
