I still don't get how anyone is quoting the First Amendment. You cannot claim a religious exception if your actions (or inactions) cause my kid to get sick from your kid because you refused to get him vaccinated.
That's like saying, "My religion believes that we should go help those in need with ebola. But, our religion forbids us from wearing masks or being tested for ebola when we return to the US, and in fact we must go out into public to spread our message in as many public gatherings as possible. Because it's our religion, you cannot stop us."
