These materials were created under the direction and support of the Partnership for Health Advancement in Vietnam (HAIVN) through Cooperative Agreement  NU2GGH001140-05 from the U.S. Centers for Disease Control and Prevention with funding from the U.S. President’s Emergency Plan For AIDS  Relief (PEPFAR). By promoting an understanding of the meaning of Undetectable = Untransmittable (U=U), these materials are part of a broader initiative to reduce HIV-related stigma and to promote access to HIV testing, prevention, and treatment services in Vietnam.
