Because SAG does not employ performers they do not have a SAG mandatory vaccine policy. Performers are employed by the production company and production companies are permitted to announce mandatory vaccine requirements.
Productions are permitted to post on the Breakdown that they are a mandatory vaccinated jobsite. They must go through the interactive process with the performers to determine whether or not they can accommodate performers that are not vaccinated. It is up to the individual production to decide if they can or can not accommodate medical or religious exemptions.
