The United States Tennis Association reversed its lax protocols for the US Open tournament, amid pressure from the New York City Mayor's Office. 

Initially, the USTA had said that the fans would not require any proof of vaccination or a recent negative coronavirus Test report for the fans to enter. The Tennis Association had also said there will be no mask mandates.

However, the New York City Mayor's office intervened to pressurize the association to have stricter protocols amid the coronavirus pandemic.

The US Open via Twitter announced on Friday evening about the reversal in the policy that had been almost non-restrictive considering the pandemic. Fans should be required to get at least one shot of COVID vaccination according to the new announcement. However, there are no masks mandates.

“Today, the U.S.T.A. was informed that the New York City mayor’s office will be mandating proof of Covid-19 vaccination for entrance to Arthur Ashe Stadium,” the statement said.

“Given the continuing evolution of the Delta variant and in keeping with our intention to put the health and safety of our fans first, the U.S.T.A. will extend the mayor’s requirement to all U.S. Open ticket holders 12 years old and older.”
