Fox tightens its vaccine rule, removing a test-out option for N.Y.C. office workers.

Fox News employees in New York City will no longer be able to get tested weekly if they don't show proof of having at least one dose of the Covid vaccine by December 27.

The new policy was in line with the vaccine rule of New York City, which Mayor Bill de Blasio announced in December and which is more stringent than the Biden administration rule.

The New York City mandate, which requires on-site workers at all businesses, is the most sweeping local vaccine mandate in the country.

A spokesman for Fox Corporation said in an email that the policy reflected the guidelines of the mandate. The company said that more than 90 percent of their employees are vaccine free.

New York is facing a surge of coronaviruses. On Friday, the state reported the highest number of new coronaviruses in a single day since the beginning of the Pandemic.

New York requires recipients of Pfizer and Moderna vaccines to get a second dose, but the policy does not currently require booster shots.
