COVID-19 Update Posted on August 9, 2021August 21, 2021 by stephenfleming The 7th Interstellar Symposium is being hosted by the University of Arizona in Tucson. Events will take place in university buildings as well as commercial buildings (such as the Marriott) nearby. Section 15-1650.05 of the Arizona Revised Statutes prohibits public universities from requiring COVID-19 vaccination or from imposing mandatory COVID-19 testing based on vaccination status. In accordance with the new Arizona statute, the University will continue to strongly encourage, but not require, that all members of the campus community be vaccinated. 13 August update: The University of Arizona is implementing a new policy to require face masks be worn in all indoor spaces where it is not possible to adequately and continuously maintain social distance. We will post more details as they become available.
