NEW YORK, NEW YORK - SEPTEMBER 27: (L-R) Co-teachers at Yung Wing School P.S. 124 Marisa Wiezel (who is related to the photographer) and Caitlin Kenny give a lesson to their masked students in their classroom on September 27, 2021 in New York City. New York City schools fully reopened earlier this month with all in-person classrooms and mandatory masks on students. The city's mandate ordering all New York City school staff to be vaccinated by midnight today was delayed again after a federal appeals court issued a temporary injunction three days before the mayor's deadline.
