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?
