In an August 24 email to registered attendees, ARM said it would be announcing new health and safety requirements for the conference that required either vaccination or a negative COVID-19 test completed within 72 hours of the start date of the event.

ARM advised registered Meeting on the Mesa attendees to upload a digital copy of their vaccination record or negative COVID test to their web-based registration page, available on the meeting's website. Meeting registrants who do not wish to comply with the new requirements have until September 1 to request a refund of their registration fee, according to the group.
