About the IAS

Who we are

IAS – the International AIDS Society – leads collective action on every front of the global HIV response through its membership base, scientific authority and convening power.

Founded in 1988, the IAS is the world’s largest association of HIV professionals, with members in more than 170 countries. Working with its members, the IAS advocates and drives urgent action to reduce the impact of HIV. The IAS is also the steward of the world’s most prestigious HIV conferences: the International AIDS Conference, the IAS Conference on HIV Science, and the HIV Research for Prevention Conference.

What we do


The IAS is the steward of the world’s most prestigious HIV conferences, each convened biennially. These conferences have established a gold-standard meeting that convenes the world’s top scientists, civil society members and policymakers to jointly discuss the fight against HIV. For more information, visit the IAS Conference section.

International AIDS Conference

The International AIDS Conference is the premier global platform to advance the HIV response. As the world’s largest conference on HIV and AIDS, it sits uniquely at the intersection of science, advocacy and human rights, bringing together scientists, policy makers, healthcare professionals, people living with HIV, funders, media and community. Since its start in 1985, the conference continues to serve as an opportunity to strengthen policies and programmes that ensure an evidence-based response to HIV and related epidemics.

IAS Conference on HIV Science

The IAS Conference on HIV Science is the world’s most influential meeting on HIV research and its applications. This biennial conference presents the critical advances in basic, clinical and operational HIV research that move science into policy and practice. Through its open and inclusive programme, the meeting sets the gold standard of HIV science, featuring highly diverse and cutting-edge research.

HIV Research for Prevention Conference

HIV Research for Prevention is the only global scientific conference focused exclusively on the challenging and fast-growing field of HIV prevention research. HIVR4P fosters interdisciplinary knowledge-exchange on HIV vaccines, microbicides, PrEP, treatment as prevention and biomedical interventions as well as their related social and behavioural implications.

IAS Educational Fund

To make scientific fora more accessible to our members, their communities and the HIV workforce, the IAS convenes smaller scientific symposia around the world targeted at healthcare workers, advocates, and policymakers. Through these smaller scientific meetings, the IAS Educational Fund provides access to the latest science and opportunities to question how that information impacts local epidemics. For more information, visit the IAS Educational Fund.

HIV Programmes and Advocacy

We promote the implementation of evidence-informed and human rights-based strategies for improving the lives of people living with and most vulnerable to acquiring HIV. Through our various programmes and campaigns, we harness research, shape the evidence base and amplify the voices of vulnerable communities to influence policy across the HIV prevention to care continuum. For more information, visit the IAS Programmes and Advocacy section.

How we do it

Science. People. Progress.

Science. The IAS pursues and supports scientific advancements that positively alter the course of the HIV epidemic and promote greater understanding of these discoveries. The IAS pushes for the full spectrum of scientific achievement – from basic science to implementation research – and use the visibility of its meetings to highlight dynamic, innovative work.

People. The IAS invests in professionalizing and promoting the HIV workforce – particularly the next generation of HIV professionals – to build the skills and resources that are needed to end the epidemic. As a membership body, the IAS understands and represents the interests of its members in all of its work, retaining a global perspective that is relevant at a local level.

Progress. The IAS uses its scientific authority to move science into policy and policy into tangible impact against the epidemic. The IAS advocates for sustained global leadership and increased investment while keeping the fight against stigma and discrimination at the heart of its work.
