"As soon as possible, but no later than October 13, 2021, operators or hosts of indoor Mega-Events and Large Indoor Events must require all staff to show proof, before entering the facility, that they are Fully Vaccinated, subject to any applicable requirements of federal, state, or local laws requiring accommodation. For clarity, “staff” as used in this Section 7 does not include all individuals included in the broader term “Personnel.” Performers or players who are not employed by the Business, governmental entity, or other organization hosting the event (e.g., members of visiting teams and independent performers not employed by the host) are not covered by this Section, but are strongly encouraged to be Fully Vaccinated before playing or performing in San Francisco."
