Some 500 doctors who serve Jewish communities across North America have signed on to a letter calling on all children and healthy adults to be vaccinated.

“We the undersigned doctors who faithfully serve the Orthodox Jewish communities of North America, strongly urge all members of our community to receive all recommended vaccinations,” the letter begins.

The letter is signed by doctors from states including New York, New Jersey, California, Florida, Texas, Arizona, Ohio, Illinois, Pennsylvania, Michigan, Missouri, Minnesota, Massachusetts and Wisconsin, as well as Toronto and Montreal. It calls on individuals and Jewish communities to work together to “prevent harmful diseases from spreading.” ‎

“We are aware of the dangerous misinformation campaign being spread and reject any unproven unscientific statements that contradict all available current science-based studies on vaccinations,” the letter says.

The letter is being featured in a mass information campaign to the Jewish community about vaccinating, the Yeshiva World News reported.

The majority of Orthodox Jewish children are vaccinated, according to statistics issued by the New York state and New York City health departments, and prominent rabbis in New York have called on their followers to vaccinate their children.

The United States has confirmed 555 measles cases in 2019, the Centers for Disease Control and Prevention announced Monday. That’s 50 percent higher than the total number recorded for 2018. The majority of the cases are centered in New York City and its large haredi Orthodox community.
