New York City declared a public health emergency and ordered mandatory measles vaccinations amid an outbreak in Brooklyn, which has become the latest national flash point over refusals to inoculate against dangerous diseases.
Outbreaks nationwide have forced state and city health officials to pursue tougher stances, such as mandatory vaccines or banning unvaccinated children from public places, prompting legal challenges and judicial intervention.
New York's mandate comes as health officials have scrambled to blunt the spread of measles. At least 285 people have contracted the disease in the city since September, mostly in Brooklyn's Williamsburg neighbourhood.
"This is the epicentre of a measles outbreak that is very, very troubling and must be dealt with immediately," Mayor Bill de Blasio (D) said. "The measles vaccine works. It is safe, it is effective, it is time-tested. … The faster everyone heeds the order, the faster we can lift it."
The mandate orders all unvaccinated people in four Zip codes, including a concentration of Orthodox Jews, to receive inoculations, including for children as young as 6 months old. Anyone who resists could be fined up to US$1000.
