Till now, it was unclear whether or not a survived SARS-CoV-2 an infection or COVID-19 results in persistent immunological reminiscence and thus can shield towards a brand new an infection.
A number of research had proven that SARS-CoV-2 particular antibodies are solely detectable for a couple of months in many individuals who’ve survived COVID-19 and will subsequently solely present momentary safety towards re-infection.
A analysis staff on the Medical Middle – the College of Freiburg led by Dr. Maike Hofmann, Dr. Christoph Neumann-Haefelin, and Prof. Dr. Robert Thimme have now been in a position to present: after restoration from SARS-CoV-2 an infection, immune cells are shaped which stay within the physique and will mediate a fast immune response in case of re-infection.
The Freiburg research was revealed within the on-line version of the famend scientific journal Nature Medication on November 12, 2020.
These so-called reminiscence T-cells after SARS-CoV-2 an infection look much like these after the actual flu. We’re subsequently assured that almost all of people that have survived SARS-CoV-2 an infection have some safety towards re-infection with SARS-CoV-2.”

Professor Thimme, Medical Director of the Division of Medication II, emphasizes how essential a great translational analysis surroundings resembling that on the Medical Middle – College of Freiburg is within the present state of affairs:
“With a view to acquire sturdy analysis outcomes inside a couple of months, shut networking between clinic and science on the highest stage is a fundamental requirement: On the one hand, sufferers with COVID-19 are handled on our wards and proceed to be cared for in a particular outpatient clinic even after the an infection has healed. Alternatively, our clinic has nice experience within the evaluation of immune cells in viral infections resembling hepatitis B and C.”
The Medical Middle – College of Freiburg shouldn’t be concerned within the improvement of vaccines towards SARS-CoV-2. Nonetheless, Dr. Neumann-Haefelin, Head of the Gerok Liver Middle on the College Hospital Freiburg, is optimistic: “Our outcomes recommend that immunity towards SARS-CoV-2 could be achieved after an an infection. Equally, vaccines presently being examined in trials might present vital safety towards SARS-CoV-2”.
“The deciphering of advanced immune responses has lengthy been a part of the analysis focus of the College and the Medical Middle – College of Freiburg. Because of the excessive scientific high quality onsite, we are able to now make an essential contribution to the corona pandemic,” says Prof. Dr. Norbert Südkamp, Dean of the Medical College on the Albert-Ludwigs-College of Freiburg.
