I don't recall if I've ranted on here about my opinions on flu shots. I was telling someone recently that they make those things the year before based on what they think the prevailing strain will be, though, and just like Fate wanted to prove me right, there's this headline today:
CDC says flu shots may not be good match for 2014-15 virus
They say that it's because the virus has mutated, but of course, this likely means that they didn't anticipate how the virus would mutate. Cold and flu viruses always mutate -- it's called evolution, and that's how they survive.
So if you haven't already gotten your flu shot this year, don't bother -- sounds like this year's vaccine won't do you any good, even if you do believe it flu shots.
And I'll save my rant on flu shots for another post.
