This was the first autumn in, like about ten autumns, that I didn't bother with getting the influenza vaccine.
And guess what I have now.
I guess I should have bothered.
However, the vaccines seem to affect different people different ways; just because I've myself had nothing but effective results from them, doesn't mean others will too.
It's a roll of the dice; one tries it, to see what happens.
In my case, the dice came out for me, but I'm aware they might roll the other way for others.
