"A kid doesn't have to be sacrificed for a stupid adult."
That's ridiculous.
I want myself vaccinated for selfish reasons. I don't want to get sick. I don't want people special to me to get sick.
I want the children to get vaccinated (when the experts believe it's time, as I defer to their judgement) for altruistic reasons. I don't want them to get sick. I don't want the people that are special to those children to get sick.
So far as the anti-vaxxers rights? Well, a little Darwinism might be good for the species as a whole...
