The past few months have seen a steady progression of both vaccine distribution and venue reopenings, but now the two have intersected. Red Rocks Amphitheatre—which just last month reopened to reduced capacity crowds—has announced that vaccines will now be available at concerts. Those over 18 years of age who want to receive the single-dose Johnson & Jonhson vaccine will be able to do so beginning tonight, May 13th, at a socially distanced Diplo concert.

In a coordinated effort with the Denver Department of Public Health and Environment (DDPHE), Red Rocks organizers are also offering anyone who does choose to get vaccinated at the iconic Morrison, CO venue a voucher good for one free Red Rocks 80th-anniversary t-shirt. According to the city of Denver, these vaccination efforts will be focused on younger groups who may not have as immediate access to the vaccine as older audiences. Up to 100 doses will be available to concertgoers on a first-come, first-serve basis.

“The entertainment industry only works when people are able to gather together, and a healthy audience is vitally important at Red Rocks,” Red Rocks spokesperson Brian Kitts told Colorado’s 9News. “We’re making it easy to come to a concert and leave knowing that our fans have protected themselves, their families and their fellow music lovers.”

The promotion is set to run through the summer at Red Rocks, which continues to add new shows to an already busy 2021 schedule.
