The 47th Annual Meeting will take place at the Heinrich-Lades-Halle located in the center of Erlangen just a few minutes from the main railway station, hotels, and restaurants. The highlight of the 2017 meeting will be the celebration of the 50th birthday of the DGfI. To salute this special occasion, the organizing committee will compile an exciting scientific program highlighting current research topics in basic and translational immunology in plenary sessions, main symposia, and workshops. A poster exhibition “50 years DGfI-50 discoveries” and a Festschrift will commemorate the history of our society and the highlights of Immunology in Germany. We will finish with an unforgettable birthday party on the last evening of the congress.
