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.
IAS 2025 will also address the current political and financial issues affecting the HIV response, including the implications for Africa and around the world.

Language matters
At the IAS, we actively use language that puts people first. This is because words have power: they bestow or remove dignity, build or break stigma, and divide or unite the HIV response. Through the words we choose to use at the IAS, we acknowledge that a person is so much more than a condition; we promote inclusivity, dialogue and equality.

Inclusion is a priority for IAS 2025. We offer lower registration fees for delegates from upper-middle, lower-middle and low-income countries, as well as students, postdocs and young people.
