The socially responsible thing would probably be to forgo a flu shot, BUT, as others have pointed out, FF are probably more at risk than many other people. I have to admit that as soon as I heard about this problem, I had the strong urge to go and get the shot, even though I don't normally! Human nature, I suppose. Having said that, it probably isn't going to be as easy as simply requesting it: I suspect there's going to be a lot of "gatekeeping" going on at doctors offices.
