We do not know what local ordinances regarding vaccine and/or testing status will be in December of 2021. Because these rules and guidelines are ever evolving, we will update metallica.com and send all ticket buyers an update 30 days in advance of the shows as to what will be required, if anything, for entry into the show. However in the meantime, we strongly recommend that you get fully vaccinated prior to the concert date as this will be the best way to keep everyone safe and healthy and to keep these show on the calendar! Visit vaccines.gov for more information or to book your appointment. Our friends outside the U.S. should consult with their local pharmacy or government website.
