International Symposium – From Paradigms to Paradoxes in Immunity and Immunopathology (PPII)

Freiburg October 6th-8th 2022 – Save the date!

The conference will highlight and discuss conceptual shifts in basic and translational immunology, infection immunity, immunodeficiency and autoimmunity. It will take place at the University Building KG I located in the heart of Freiburg just a few minutes from the main railway station, hotels and restaurants.

The organizing committee is compiling an exciting scientific program with plenary sessions held by internationally renowned speakers complemented by selected short talks from young scientists.

We cordially invite everyone to join us in Freiburg for this exciting meeting. All Freiburg’ immunologists are looking forward to welcome you to our city with the charm of a small historic town in the heart of the famous Black Forest. We hope to make this special conference a memorable event!
