But Dr. Milhoan said that making the vaccines optional, rather than requiring them for entry into public schools nationwide, as is now the case, would ultimately restore trust in public health.

So, they already are optional. It's just that there are consequences for choosing that option (can't get into public schools), and Republicans hate consequences. Except, dying from measles, or getting paralyzed by polio, are also consequences.

I'm beginning to think that this is really just a ploy to make public schools unsafe, so that people that can afford it shift to for profit private schools, which of course will be allowed to continue to require vaccines.
