Combined scientific study data from 2008 up to today, shows zero linked HIV sexual transmissions after more than 100,000 condomless sex acts, with both heterosexual and same-sex male serodifferent couples (couples where one person is living with HIV and the other not), where the partner living with HIV had a durably undetectable viral load.
This data is part of the evidence base for the medical breakthrough referred to as “HIV treatment as prevention,” and the public health message that “undetectable equals untransmittable,” or U=U. Evidence further backed up with the archived patient data across a longer period of time.
The findings made it clear an effort was needed to tackle misconceptions surrounding people living with HIV on effective treatment, within the adult film industry. It also became clear there was a commonly a false sense of security and overlooking of HIV test "Window periods" factors for performers about to be filmed with. As such the Porn Producers for Safety Against Discrimination Pledge was created.
