To date, it has not been clear whether the surviving SARS-CoV-2 infection or COVID-19 is a permanent immune memory and therefore can be protected against a new infection.
Several studies have shown that the specific antibody SARS-CoV-2 can be detected in many people who have survived COVID-19 in just a few months and therefore can only provide temporary protection against re-infection.
A research team at the Medical Center – at the University of Freiburg, has been able to show what Dr. Maike Hofmann, Dr. Christoph Neumann-Haefelin and Dr. Robert Thimme have shown: that they can mediate if they become infected again.
It was published in the online edition of the prestigious scientific journal Freiburg Nature Medicine November 12, 2020.
These so-called memory cells after the SARS-CoV-2 infection are similar to those from the real flu. Therefore, we are confident that most survivors of SARS-CoV-2 infection have some protection against SARS-CoV-2 reinfection.

Professor Thimme, Medical Director of the Department of Medicine II, emphasizes the importance of a good translational research environment in the current situation, such as the Medical Center – University of Freiburg:
“In order to achieve strong research results in a few months, the close link between clinic and science is a basic requirement at the highest level: On the one hand, patients with COVID-19 continue to be cared for and treated in our wards. has a high impact on viral infections, such as the analysis of immune cells such as hepatitis B and C.
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 Freiburg University Hospital, expressed optimism: “Our results suggest that immunity to SARS-CoV-2 can be achieved after an infection. SARS-CoV-2 “.
“Deciphering complex immune responses has long been part of the research focus of the University and Medical Center – Freiburg University. In its high scientific quality, we can now make an important contribution to the pandemic of the crown,” says Prof. Dr. Norbert Südkamp, Dean of the Faculty of Medicine at the Albert-Ludwigs-University of Freiburg.
