Flu Vaccine: Do it or not?

[Fidel_Castronaut]

I have a flu shot every year because, as a diabetic, I'm more liable to get ill and/or complications from influenza viruses.

I think people also forget just how deadly influenza really is. As a virus it's responsible for millions of deaths each year. And let's not forget entities such as Spanish flu, which killed more people post WWI than those who died during the conflict (WIKI estimates up to 3-5% of the world's population).
