Wasps will take part in Saturday’s Premiership final against Exeter Chiefs at Twickenham, despite 11 Covid-19 cases within the club in the past week.
Premiership Rugby confirmed Lee Blackett’s side were clear to play after the latest round of testing.
Bristol were on stand-by if Wasps, who beat them in the semi-finals, had been unable to fulfil the fixture.
The decision was taken by the Rugby Football Union, Premiership Rugby and Public Health England officials.
This will be Wasps’ first final since 2017, when they were beaten by the Chiefs in extra time.
Seven players and four backroom staff had been diagnosed with coronavirus before further tests were undertaken on Tuesday.
But in a statement, Wasps confirmed that “no further players or staff have tested positive”, although a coaching staff test was damaged in transit and that member will now self-isolate as a precaution.
They also reiterated the need to maintain their “rigorous” protocols around track and trace as the players return to training for the game.
“I would like to place on record my sincere thanks to Premiership Rugby, the RFU, Public Health England and Public Health Warwickshire for their clarity and assistance throughout this whole process,” Wasps group chief executive Stephen Vaughan said.
“As a club, we are delighted that we can now take our rightful place in this Saturday’s Premiership Rugby final. To all of our fans and well-wishers, thank you for your many messages of support, this final is for you.”
