Watch: Neil Patrick Harris and Other Out Actors Ask 'Why Aren't We Talking About HIV/AIDS?'

To help the fight against HIV and AIDS, GLAAD has teamed up with The Elizabeth Taylor AIDS Foundation to create a star-studded PSA, set to air exclusively on Logo.

Clips of Elizabeth Taylor's iconic speech at the 1992 Freddie Mercury Tribute Concert are featured, as well as appearances by openly gay actors Neil Patrick Harris, Nathan Lane, Tituss Burgess, and Daniel Franzese.

It has been twenty years since her speech and Taylor's words are still poignant. Despite the existence of preventive drugs, one in five gay men in major cities have HIV.

"HIV infection rates are up 133% in last decade among young gay men," Joel Goldman, managing director of The Elizabeth Taylor AIDS Foundation says. "It's troubling that one in three gay men have never had an HIV test. We must find new ways of raising awareness in order to reach this community and inform them of the tools available to prevent new infections. We are so fortunate to have the support from Logo as well as our incredible partners at GLAAD on this PSA campaign."
