A VISION TO END AN HIV EPIDEMIC
Eastern Europe and Central Asia (EECA) is recognised as one of the few regions in the world where the HIV epidemic is getting worse, with new HIV cases increasing by 20% and AIDS-related deaths increasing by 34% since 2010. RADIAN, a transformative partnership between Gilead and the Elton John AIDS Foundation, seeks to change that.
RADIAN is addressing the HIV crisis in EECA by supporting community-led solutions that pilot and scale new care models where the need for HIV services is the greatest.
For more than five years, these organisations have supported people affected by the HIV crisis in the region through community-based services and health systems and by addressing structural barriers impeding the HIV response.
And the impact so far is real:
-
367,000+
people have been reached with direct services, increasing HIV service coverage for those who need it most
-
177,700+
HIV tests have been provided
-
36,650+
people living with HIV (both newly diagnosed and those people lost to follow-up) have been linked to care
-
19,200+
frontline workers have been trained to reduce stigma and improve quality of and access to care for key populations

Scaling Success:
Meeting EECA’s Evolving Needs
RADIAN has been reshaping the HIV response in EECA since 2019. Now, RADIAN is set to scale and innovate on these proven success models over the next five years.

Our Reach
We’ve expanded our geographic reach to respond to urgent needs and support communities facing the greatest barriers to care. This includes partnering with new organisations in EU countries hosting people displaced by the ongoing conflict in Ukraine, helping to improve their access to HIV services and strengthening their mental health and social wellbeing.

Scaling Change
RADIAN supports partners in replicating their successful models in other locations. RADIAN Model Cities is one such model that helps to strengthen clinical and community-based HIV service delivery in key EECA cities. We’re adapting a proven model of care implemented in Almaty, Kazakhstan for Samarqand Oblast, Uzbekistan — the country with the third-largest HIV epidemic in EECA.

Innovation
In 2025, we launched three new funding streams:
- The Innovation Challenge Fund to support new and original ideas around challenging stigma and delivering HIV services
- The Equity Challenge Fund to address the root causes driving the HIV epidemic in the region
- The RADIAN Success Replication Fund to support RADIAN grantees in scaling programmes that work
