Nope, never do.
But I do love the annual flu shot hype, last year's being the best. First there's the big push to get everybody to get the shot. If you don't get the shot, you will drop dead.
Then there's the inevitable shortage. If you are old or a member of specific groups, you must get the shot or drop dead. Everyone else will be fine if they don't get the shot, and they should stop worrying about it.
Then the supply catches up. Now all those people who didn't get the shot should get it immediately or again they will drop dead (even if flu season is over).
