A bar in Seattle’s Capitol Hill neighborhood is now requiring proof of COVID-19 vaccination for entry.

CC’s posted on its Facebook page that the new policy will take effect May 22. The post pointed to constant changing of mask directives as part of the reason for the new policy, saying the changes “caused confusion and frustration over the right thing to do.”

The bar said that the policy protects staff and everyone who chooses to enter and provides incentive to get vaccinated.

“We understand this may be inconvenient or controversial for some, but it is safer for everyone in the long run,” the post read.
