Prof. Dr. Martin Bachmann is a visiting professor at Anhui Agricultural University in Hefei, the capital city of Anhui in China. As an essential role of our collaboration with Anhui Agriculture University in different animal vaccines, Prof. Martin, Prof. Lisha Zha and the directors of Anhui University have organized an immunology summer-school in October 2019 in China. The summer-school included a number of important local and international speakers: From our lab; Prof. Martin Bachmann, Dr. Monique Vogel, Dr. Mona Mohsen and Xinyue Chang (PhD student), Prof. Thomas Kundig (University of Zurich), Prof. Daniel Speiser (University of Lausanne), Dr. Gary Gennings (HypoPet AG), Dr. Aadil El-Turabi (University of Oxford), Dr. Ariane Gomes and Dr. Joshua Blight (Imperial College London). The speakers discussed a wide rage of topics in immunology which opens the door for promising projects in collaboration with China. The Chinese have shown us extraordinary warmth and generosity. The summer-school was ended with a magical tour in the yeloow mountains.
