We need laws to protect us from stupid people.

We need laws to protect us from stupid people. Parents who refuse to vaccinate their children should be held criminally liable. They're not just putting their own child's life in danger, but others as well.
1. Vaccines are not anywhere near 100% effective, so even a fully vaccinated person may be relying on herd immunity.
2. You can't vaccinate a newborn, so everyone relies on herd immunity for the first 6 months or so of their life.
3. Some people can't be vaccinated at all (extreme health issues).
