Does this mean that a fractional percentage of people aren't at risk of a bad reaction to these vaccinations? No, of course not, but the vast, vast majority of people are protected by them. As well, and as a species, we benefit from a "herd effect"--in other words, society is protected by the fact that we are all (supposed to be) immunized. That herd protection is eliminated by those who are not vaccinated.
I'm willing to go one step further than most people--I think that those who peddle these dangerous ideas are guilty of criminal negligence. At the very least, they should be open to civil suits.
