This is the ultra orthodox Jewish community. They’re not overwhelmingly educated beyond their own yeshivas. Those yeshivas have been shown to provide less than standard education to their community. There was an orthodox woman interviewed on the news last night that clearly stated her reasoning is that she doesn’t want her children exposed to something that altered their immune system. You’re absolutely correct, it isn’t true religious opposition at all. They’re using that as a loophole. It’s an undereducated, easily manipulated community that is being targeted by the greater anti-vaccine movement.
