Unfortunately, there is a measles outbreak in some east coast cities where some parents refused to vaccinate their children claiming religious exemption.
Since the situation has been declared an outbreak, the religious exemption is not enough to allow unvaccinated children into school. But apparently under normal circumstances there are Jews using religious exemption not to vaccinate, and this is being accepted.
Without getting in to a discussing about who's right or wrong (or just plain crazy), I'm curious what the claimed 'religious exemption' is?
