Cyanide

Well, that does sound fairly conspiracy theory-like. I would want some proof before I believed that. Being a military doc, I have not heard of any "special vaccines". Considering we are the ones that deal directly with our political leaders on frequent occassion, I would have expected some information to come my way. I got the vaccine yesterday. And I don't believe this is going to result in any neurological damage. That probably refers to the chicken pox vaccine developed in the 1970's. Hey, live and learn I guess. If you have humans in the algorithm, expect occassional human errors. Its pretty unlikely that a botch-job like that vaccine will ever happen again.

I hope you aren't talking about the mercury in the thimerosal causing autism myth. That has been repeated and thoroughly debunked on every possible level. Quite frankly, too much good money was wasted disproving that over and over again. Money that could have been used to further other medical research. The only ones sticking to it are the crack-pots.

Beyond that, the only mentionable risk is Guillian Barre Syndrome. Over 90% of that completely recovers, the high high high majority of cases are sporadic and can't be pegged to any particular trigger, and probably occurs more sporadically than anything else. I would certainly fear the complications of a nasty flu than I would the GBS. But, that boils down to likelihood ratios (its far more likely to get a bacterial pneumonia secondary from getting swine flu than it would getting GBS from the vaccine)
