Founded in 1988, the International AIDS Society (IAS) is the world’s largest association of HIV professionals, with members in more than 170 countries. The IAS advocates and drives urgent action to reduce the impact of HIV and organises one of the world’s most prestigious HIV conferences: the IAS Conference on HIV Science. This biennial conference presents critical advances in basic, clinical, and operational HIV research that move science into policy and practice.


Given the limitations of the COVID-19 pandemic, the IAS conference on HIV science to be held in Berlin, Germany on 18–21 July 2021 had to be staged virtually.
