School buses line up outside the Yeshiva Kehilath Yakov School in the South Williamsburg neighborhood on Tuesday in the Brooklyn borough of New York City. New York City has ordered all yeshivas in a heavily Orthodox Jewish section of Brooklyn to exclude from classes all students who aren't vaccinated against measles or face fines or possible closure. The order comes amid a recent outbreak of over 285 measles cases in Brooklyn and Queens, most of which have been concentrated in the Orthodox Jewish communities. (Drew Angerer/Getty)
