As it should be. Don’t expose your unvaccinated kids to the public. That’s irresponsible. If you want to keep your kid vaccine free pointlessly, you should keep them in quarantine, like the bad parent you are.
If your kid can’t be vaccinated for a real reason, like they’re allergic to the vaccine, then by all means, they can go to school. But your personal philosophy isn’t grounds to put everyone else at risk. Your personal philosophy can’t hold a candle to the science and facts.
So either vaccinate your kid (like a responsible parent), or keep your disease carrier to yourself and out of contact with people who have compromised immune systems or otherwise can’t be vaccinated (like a less responsible parent, who is denying their child the national and international standard of care that’s been essentially proven to work and prevent epidemics).
I’m not sold on the idea that antivaxxers should be allowed to keep their children in quarantine either. As far as I’m concerned denying the kid the standard of care for no reason is the same as neglect and child abuse. I’m tired of JWs killing their children by not allowing blood transfusions, and faith-healer sects letting their children die of preventable and treatable diseases.
Children are NOT their parent’s property. They’re human beings. And the parents have a duty to their children, enforceable by the state, to provide adequate care, feeding and education. Not fulfilling such duties is neglect and abuse, pure and simple. So it might be time to start prosecuting parents who allow their children to contract diseases like measles and pertussis because they didn’t vaccinate when they could have.
