With policy and science evolving at a rapid pace, opportunities for education, networking and the promotion of best practice are critical to enhance the global response to AIDS. Through its renowned conferences, the IAS provides an essential forum for a broad spectrum of HIV professionals to share their expertise and real-world experiences, and identify remaining knowledge gaps.

The IAS organizes the world’s two most prestigious HIV conferences, each convened biennially in alternating years. The International AIDS Conference is the largest conference on any global health or development issue. First convened during the peak of the AIDS epidemic in 1985, this conference continues to provide a unique forum for the intersection of science and advocacy, and an opportunity to strengthen policies and programmes to ensure an evidence-based response to the epidemic. The conference also serves as a focal point to intensify political and financial commitments to AIDS. Additionally, the IAS provides the largest international HIV conference scholarship programme, to ensure those living with and affected by the disease are well-represented at the gathering. The next International AIDS Conference (AIDS 2020) will be held in San Francisco and Oakland, United States  (6-10 July 2020).

The IAS Conference on HIV Science features the latest HIV science, including basic, clinical and prevention research. It brings together a broad cross section of HIV professionals from around the world with a focus on implementation – moving scientific advances into practice. The next conference (IAS 2019) will take place in Mexico City, Mexico in July 2019.

HIV Research for Prevention (HIVR4P) is the only global scientific conference focused exclusively on the challenging and fast-evolving field of biomedical HIV prevention research. HIVR4P supports cross-fertilization among research on HIV vaccines, microbicides, PrEP, treatment as prevention, and other biomedical prevention approaches, while also providing a venue to discuss the research findings, questions, and priorities specific to each. The conference has been organized every two years since 2014. Traditionally organized by the Global HIV Vaccine Enterprise (GHVE), the IAS, selected as the GHVE host institution from 2018, is taking full ownership of the conference as of 2019. HIVR4P 2020 will be organized 11-14 October 2020 in Cape Town, South Africa. More information on HIVR4P can be found at
