New York City Mayor Bill de Blasio has ordered residents of a Brooklyn neighborhood to undergo mandatory vaccinations or pay a fine.
Declaring a public health emergency Tuesday, the mayor insisted the order was necessary to address the measles "crisis" in Brooklyn's Williamsburg community, a neighborhood of more than 250 ultra-Orthodox Jewish residents.
"The declaration requires all unvaccinated people who may have been exposed to the virus to get the vaccine, including children over 6 months old," reports the Associated Press.
The order affects people residing, going to school or working within four ZIP codes: 11205, 11206, 11221 and 11237.
De Blasio said anyone in these areas must receive the measles vaccine or get fined up to $1,000.
