ALBANY— The state’s top doctors’ group Monday backed legislation aimed at cracking down on the measles outbreak by banning religious exemptions for vaccinations.

“The Medical Society of the State of New York is . . . asking our NYS legislators to authorize ONLY medical exemptions from vaccination,” said Medical Society president Art Fougner.

“We must do everything that we can to prevent measles from gaining a permanent foothold in New York and prevent the further spread of disease nationally. An important first step is ensuring that medical exemptions are the only exemption allowable.”

The US Centers for Disease Control and Prevention reported the outbreak is the worst in 25 years, with over 700 cases across 22 states reported last month, and upwards of 500 directly resulting from cases where the infected individual was not vaccinated.

Parts of Rockland County and an orthodox Jewish section of Brooklyn — Williamsburg — have been hardest hit, with emergency orders issued in both areas.

The vaccination bill is gaining support and could pass both houses of the Democratic-run Legislature — the Assembly and Senate, legislative sources said.

“There are a few people I think that might be skeptical [that] are concerned that eliminating the religious exemptions may raise a constitutional issue. I think that’s been disposed of as far as I’m concerned,” Assembly bill sponsor Jeffrey Dinowitz (D-Bronx).

The vaccine proposal comes at a time when education advocates are fighting for “substantial equivalency standards” in orthodox Jewish schools, called yeshivas.

Naftuli Moster, a yeshiva graduate and director of Young Advocates for a Fair Education, said the fight over standards in non-public schools and the measles outbreak are related. Anti-vax misinformation has spread among some parents.

“I think it’s a double whammy, people who don’t know much science and barely get an education, they’ve never heard about the history of diseases,” Moster said.

“There’s another link, the containment issue, the city is so frantic because the city hasn’t had their finger on the pulse.”

But in a recent interview, Cuomo stopped short of saying there’s a link between the education curriculum in yeshiva and the measles outbreak.

“I don’t want to speculate on any connection with measles; legally they’re two separate situations. One is the education law and one is the public health law and I don’t want to speculate,” the governor said.
