Personalities appearing on some Bravo reality shows are required to agree not to sue the network if they get any of a long list of infections during production, The New York Post’s Page Six reports. The report says participants must sign a so-called “STD clause.”

“Network insiders … assure us that such provisions are common across all networks, especially on dating shows,” the story notes. “We hear that the contracts also officially warn stars that their fellow combatants aren’t tested for sexually transmitted diseases.”

The report adds: “By contrast, ABC has previously revealed that it tests contestants on its long-running dating shows ‘The Bachelor’ and ‘The Bachelorette’ for STDs. Those shows make the 50 finalists for spots in the competition get screened for sexual diseases.”

The Post reports that Bravo’s “Vanderpump Rules” appears to be “a particular hotbed of disease.”
