Have the makers of flu vaccines ever guessed the correct strain?

Let me start off saying I'm not a vaccine conspiracy nut. However, I read once again the flu vaccine isn't very effective for the flu strains commonly going around this year. That this years flu strains are very virulent and hard hitting. (Which I can attest to.) Just as last year. The year before that, and the year before that. Preceded by the year before that. So on and so on.
Has there been any year anyone knows of with a flu vaccine that has been effective for the strains being found?

I was going to say...they do they best they can. Flu viruses mutate so by the time they have vaccine ready there is already another strand, so there is unfortunately only partial protection (which is better than none at all). Let me say here too while I've got your attention....this is for those who won't get a flu shot because they believe they'll get sick. It's a dead virus that is used, it cannot possibly make you sick. Anyone who got the flu after getting the shot was already exposed to it before hand and getting sick was/is just a coincidence. Thought you'd just like to know that. Stay well.

@indyjoe I honestly don't think they do. I think they do "good enough to put on the shelf".
