Research title: Transforming global HIV prevention strategies and the lives of millions of people living with HIV.                                                               

Faculty: UCL Population Health Sciences

Activity: Research

Policy partner: UN Agencies, Other Multilateral/International Institutions


Led by research teams in the UCL Institute for Global Health, the PARTNER study signalled a potential end to the HIV endemic by showing conclusively that people whose HIV infection is fully suppressed by antiretroviral drugs have no possibility of infecting sexual partners even when condoms are not used. PARTNER’s results now underpin the global U=U (Undetectable=Untransmittable) campaign, WHO and UNAIDS guidelines, and the current US national HIV/AIDS strategy. The UCL team’s findings also have a profound impact on the lives of people living with HIV by reducing HIV-related stigma and discrimination; encouraging early testing and treatment; and combatting HIV criminalisation laws which imprison people with HIV, based on outdated assumptions that have been disproved by Rodger and Phillips’ work.
