WATCH: Three Part Vice Documentary Explores Impact of PrEP on Gay Community and HIV

Truvada, the first FDA-approved HIV prevention pill, protects users nearly 99 percent of the time from aquiring HIV. It's been mired in controversy since it was first approved, but Truvada as PrEP has changed the landscape of safer sex within the gay male community, the population hit hardest by HIV in America.

In their latest, VICE Reports explores the future of the Truvada and its revolutionary impact on ending HIV in their new three-part documentary Stopping HIV? The Truvada Revolution.

 In Part One, VICE meets with Gladstone Institute's Dr. Robert Grant, who is leading research to understand the biological and social implications of Truvada as well as Damon L. Jacobs, who is seeking to educate other gay men around the world about the revolutionary drug.

In Part Two, VICE heads to the Kink.com headquarters in San Francisco to talk with its Director of Sexual Health and Advocacy Eric Paul Leue about what works when it comes to HIV prevention. Back in New York, Michael Weinstein, the president of AIDS Healthcare Foundation, tells VICE that Truvada does not work as a public health intervention for HIV, citing adherence issues. Finally, Harlem United's Kimberleigh J. Smith discusses Truvada's accessibility to only affluent, white men.

In Part Three, VICE meets Michael and Leo, an HIV carrier and his partner, who have been together for over a year. The couple discusses their relationship with Truvada, the stigma against the drug, and how their thoughts on the treatment have changed.
