Mayor Michelle Wu announces two new requirements to address the coronavirus pandemic.

Wu also that all city workers must be vaccinated and that masks must be worn indoors in all restaurants, entertainment venues, and gyms until the virus level subsides. The announcement prompts a court suit by some city unions and demonstrations beginning in January 2022.* After virus transmissions wane, the mask requirements are rescinded on April 1, 2022 and the vaccination requirement on May 11, 2023.
