"These so-called memory T-cells after SARS-CoV-2 infection look similar to those after a real flu. We are therefore confident that the majority of people who have survived SARS-CoV-2 infection have some protection against re-infection with SARS-CoV-2," explains Dr. Hofmann, a scientist at the Department of Medicine II at the Medical Center - University of Freiburg.
Professor Thimme, Medical Director of the Department of Medicine II, emphasizes how important a good translational research environment such as that at the Medical Center - University of Freiburg is in the current situation: "In order to obtain robust research results within a few months, close networking between clinic and science at the highest level is a basic requirement: On the one hand, patients with COVID-19 are treated on our wards and continue to be cared for in a special outpatient clinic even after the infection has healed. On the other hand, our clinic has great expertise in the analysis of immune cells in viral infections such as hepatitis B and C."
The Medical Center - University of Freiburg is not involved in the development of vaccines against SARS-CoV-2. However, Dr. Neumann-Haefelin, Head of the Gerok Liver Center at the University Hospital Freiburg, is optimistic: "Our results suggest that immunity against SARS-CoV-2 can be achieved after an infection. Similarly, vaccines currently being tested in trials could provide significant protection against SARS-CoV-2".
"The deciphering of complex immune responses has long been part of the research focus of the University and the Medical Center - University of Freiburg. Thanks to the high scientific quality onsite, we can now make an important contribution to the corona pandemic," says Prof. Dr. Norbert Südkamp, Dean of the Medical Faculty at the Albert-Ludwigs-University of Freiburg.
