Billboard's Dave Brooks reports:

Monday's news that pharmaceutical company Pfizer's early results on a new COVID-19 vaccine showed a 90% efficacy rate on an initial clinical trial have given concert professionals hope that the business can start mounting a return in 2021. As part of that preparation, Ticketmaster has been working on a framework for post-pandemic fan safety that uses smart phones to verify fans' vaccination status or whether they've tested negative for the coronavirus within a 24 to 72 hour window.

Many details of the plan, which is still in development phase, will rely on three separate components - the Ticketmaster digital ticket app, third party health information companies like CLEAR Health Pass or IBM's Digital Health Pass and testing and vaccine distribution providers like Labcorp and the CVS Minute Clinic.

Here's how it would work, if approved: After purchasing a ticket for a concert, fans would need to verify that they have already been vaccinated (which would provide approximately one year of COVID-19 protection) or test negative for coronavirus approximately 24 to 72 hours prior to the concert. The length of coverage a test would provide would be governed by regional health authorities -- if attendees of a Friday night concert had to be tested 48 hours in advance, most could start the testing process the day before the event. If it was a 24-hour window,  most people would likely be tested the same day of the event at a lab or a health clinic.
