The problem with this generation is that we have aunts and uncles that were paralyzed from the polio vaccination.
Polio has been eradicated EXCEPT from vaccination issues.
Don't forget the polio vaccine was contaminated with a Monkey virus that keeps showing up in cancer cells of people who were giving that vaccine. That is not coincidence.
Of course the only casualties now are from bad reactions. Our population has increased enormously due to advances in the control of decimating disease. That makes the few failures all the more traumatic. The disease itself is virtually gone from the US population--but it could come back, the way TB is making a comeback.
I'd like to see the anti-vaccine crowd start their own country. They could use the old Hansen's colony on Molokai and spend their time swapping pathologies...wouldn't last very long.
