LION Conference postponed to 2021

After careful consideration, we have decided to postpone the Leipzig Immune ONcology Conference (LION), which was originally scheduled for 10–11 November 2020. The dynamic development of the COVID-19 pandemic and the official orders have not made this decision easy for us. However, existing restrictions regarding congress participation such as travel bans by hospitals and companies as well as possible quarantine requirements would have made it very difficult to hold a lively and attractive congress. Likewise, we as medical professionals see ourselves as having a special ethical and moral responsibility to exclude a possible risk of infection for medical personnel.

However, we are pleased to announce the new date of 9-10 November 2021.



The Leipzig Immune ONcology (LION) Conference will bring together clinicians, scientists and industry to discuss latest developments and highlights on special issues of immune oncology. The annual meeting is organized by the Fraunhofer Institute for Cell Therapy and Immunology and the University Cancer Center of the University Hospital Leipzig.
