Hopefully things have changed recently and they are more accurate in predicting which strain(s) will show up for any one season.

The new universal flu shot being made will cover all past strains (I believe it was back 100 years) as well as future strains so it'll be WAY more effective. You can watch "Pandemic" on Netflix for better details. I watched it quite a few months ago now. Current flu shots are sort of a "best guess" based on strands found in Australia since their winter occurs before ours every year.
