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.
