Dr. Jenner,
You lived in vain.
Honestly, to read this nonsense about mercury, formaldehyde, etc. you'd think we were a group of Faux news watching red-nex and not intelligent people.
I already got my general flu' shot and will get the H1N1 as soon as it's available. I keep my vaccinations up to date otherwise, too.
Sheesh.
There are two known species of mammal with a bite sufficiently toxic to be considered poisonous. We are one of them. Does that mean you're going to stop kissing?
Instead of propagating all this nonsense, try actually learning something.

There is no scientific basis for any of this crap. None. There is, however, evidence from several centuries of inoculation demonstrating it works.
I'm not sure herd immunity is quite the right term...
