Mayor Bill de Blasio says all New York City employers will have to mandate COVID-19 vaccinations for their workers by Dec. 27. De Blasio said Monday that the new mandate is aimed at preventing a spike in coronavirus infections during the holiday season and the colder months. He called it a "preemptive strike" to "stop the further growth of COVID." Vaccinations are already required for city employees including teachers, police officers and firefighters, and a vaccination mandate for employees of private and religious schools was announced last week. De Blasio said he expects the new mandate to survive any legal challenges.
