[Scientists thought they had measles cornered. They were wrong.]
Just outside the public library where Mr. de Blasio held his news conference, some Hasidic mothers raised concerns about the emergency declaration.
“I don’t think it’s up to the city to mandate anything. We all have constitutional rights,” said a woman who only identified herself by Gitty. She refused to give her last name for fear of being harassed for her rejection of vaccinations.
She said she had five children and that none had been or would be vaccinated, an action she called “a medical procedure by force.”
“We are marginalized,” she said. “Every minority that has a different opinion is marginalized.”
In nearby South Williamsburg, reaction to the emergency order was mixed. Some agreed with the need for vaccinations, but did not believe the law should require them; others agreed with the mayor.
“He’s right,” said Leo Yesfriedman, a 33-year-old father of four who said he had his family vaccinated.
He said he had followed news of the measles outbreak. Of people in his community opposed to vaccinations, he said, “It’s a very, very little percentage of crazy people.”
Health officials, noting that Passover will begin next week, were concerned that if children remained unvaccinated, measles could spread at family gatherings here or abroad.
“The outbreak could in fact especially spread because soon it will be Pesach,” the mayor said. “There will be school vacation. There will be more and more families together. The last thing we want to see is more family members afflicted by this disease.”
