Netflix on Wednesday became the first major Hollywood studio to announce a requirement for all casts and crews of U.S projects to be vaccinated against COVID-19 as the highly transmissible delta variant fuels new surges of the virus. 

The policy, which was first reported by Deadline, will require all people working in “Zone A,” which includes actors and those who regularly come into contact with them, to be vaccinated. 

The new guidelines come after Hollywood unions and major studios reached an agreement last week giving producers “the option to implement mandatory vaccination policies for casts and crew in Zone A on a production-by-production basis.”

Deadline reported that exceptions to the mandatory vaccine policy would be strict and limited to a few scenarios, including medical and religious reasons. 

The entertainment news outlet also reported that series and films already in production may be exempt from the mandatory vaccine mandate. 

The Hill has reached out to Netflix for additional information. 

The move comes after Los Angeles has already reissued a mask mandate for all individuals, regardless of their vaccination status, and implemented vaccination requirements for city employees, citing case hospitalization and death surges among unvaccinated groups. 

Several other companies, including Google and Facebook, are also requiring their workers to be vaccinated before returning to the office. 

Google CEO Sundar Pichai said in an email to employees Wednesday that the company would be extending its global work-from-home program until Oct. 18, but that anyone wishing to return to offices will need to show proof of vaccination.

“The implementation will vary according to local conditions and regulations, and will not apply until vaccines are widely available in your area,” Pichai noted in the email, adding that the company would also soon share details on qualified exceptions to the mandate. 

Facebook Vice President of People Lori Goler on Wednesday said its vaccine mandate would apply to anyone at Facebook’s U.S. offices, adding that the implementation will depend on “local conditions and regulations.”
