Below is a statement of our former colleague Professor Emeritus Rolf Steyer regarding a note published on 11/16/2021 that contains scientifically unconfirmed findings and interpretations related to German Corona vaccination policy. The Department of Psychology was not and is not in any way involved in this note and distances itself from it. We are publishing this statement from our former colleague to prevent the further dissemination of misinformation and misinterpretation. If you have any questions about this issue, please contact the press office of the University of Jena: presse@uni-jena.de.
On November 16, we wrote a short note for the member of the Thuringian state parliament, Dr. Ute Bergner. The occasion was a topical hour of the state parliament on the Corona vaccination policy. The note was written exclusively for this purpose. We agreed to pass it on to the Thuringian Ministry of Health and, after their request, also to the CDU parliamentary group. The reported and surprising correlation should be a starting point for further discussions and analyses. We regret that this note has received such dissemination. We did not authorize the dissemination and sharing of the note on the internet and social media, nor did we even initiate it.

For clarification: The note is neither a scientific publication nor a scientific study that meets our own quality standards. Our note does not prove that increased vaccination rates lead to an increased excess mortality. We do not want that our note is misinterpreted in this way. There are numerous reasons that could explain the positive correlation found without implying a negative effect of vaccination rates on excess mortality. More comprehensive scientific analyses are warranted to explain the current excess mortality. Incidentally, adding the now available data from calendar week CH41, the positive correlation we reported last week is close to zero.

We ask that this statement be brought to attention wherever our note is quoted, or even copied in its entirety.
