"The decision to implement proof of full vaccination or a negative COVID-19 test is representative of the continued commitment to providing the best environment for a safe return for all fans and employees," a United Center spokesperson said in a statement. "This new entrance process will go into effect for all future events and will remain in place until further notice."
The statement said the protocols are subject to change as the NBA and NHL have yet to release their own health and safety guidelines.

"As final NBA and NHL health and safety guidelines have yet to be announced, these protocols are still subject to potential league requirements, and the Chicago Bulls and Chicago Blackhawks may communicate additional details to their fans as the season approaches," the statement said.
All United Center and team employees will also be required to follow the same mandate, according to the statement.
Additional investments to improve the air flow within the arena have been made, according to the United Center and the venue says it has upgraded to MERV-13 air filters, which reportedly filter out more than 90 percent of air particles.
