Oh, those are "big" (as in, serious, though rare; or serious, but doesn't fucking happen...) but do you know what is bigger? Somebody who could not get immunized dying because you refused to get immunized.
If one was forced to immunize their child, that child then dies from a reaction to that vaccine. Is that the "unselfish" act? You might of well have said it's against your "morals". Your full of it, might as well say we should cull the autistic kids from the herd, you know to protect the herd.
Vaccines save millions of live. If, in your personal system of morality, the veeery slight chance that your child will die takes priority over the benefit vaccines present to society, then while you are entitled to that viewpoint, I have the right to call you a selfish monster who embodies much that is wrong with modern society.
Furthermore, neither autistic kids nor eugenics have fuck all to do with vaccinations. Quit peddling this bullshit.
