The announcements came in quick succession on Monday in the country's most populous city and state. In New York City, Mayor Bill de Blasio announced all city workers would have to either get vaccinated or tested weekly for the virus. In California, Gov. Gavin Newsom declared a similar policy for state employees and health care workers.
