Nothing. Because the people who can do anything are unwilling to act. And the people people who are willing to act, are unable to help.
As long as Yeshivas and Bais Yaakovs continue to allow disease-ridden un-immunized kids in the building under “religious exemption” were are all in deep trouble.
I’m also a little curious why so many frum people are anti-vaccine. The only professional medical knowledge frum people have should come from a doctor, who will invariably push for immunization. Other knowledge can only come from the Internet. So it’s a good Shibboiles, if someone refuses to vaccinate, they clearly have Internet and shouldn’t be allowed into Yeshiva.
