Researchers were left baffled after a man from Magdeburg, Germany claimed that he had received Man from Germany claims to have received 217 Covid-19 vaccine doses, researchers shocked within 29 months deliberately and for private reasons. Alexander-Universität Erlangen-Nürnberg (FAU) and Universitätsklinikum Erlangen found about the man from newspaper reports and studied his immune response.

"We learned about his case via newspaper articles. We then contacted him and invited him to undergo various tests in Erlangen. He was very interested in doing so," said Dr Kilian Schober from the Institute of Microbiology – Clinical Microbiology, Immunology and Hygiene in a press release.

"The individual has undergone various blood tests over recent years," explained Schober. "He gave us his permission to assess the results of these analyses. In some cases, samples had been frozen, and we were able to investigate these ourselves. We were also able to take blood samples ourselves when the man received a further vaccination during the study at his own insistence. We were able to use these samples to determine exactly how the immune system reacts to the vaccination."

According to the press release, the test subject had a high number of T effector cells that can defend the body against the virus. However, when compared to a control group of individuals who received three vaccines, they found that the man’s T effector cells were not fatigued and were similarly effective as those of the people in the control group.

"The number of memory cells was just as high in our test case as in the control group. Overall, we did not find any indication for a weaker immune response; rather, it was the contrary," explains Katharina Kocher, one of the leading authors of the study published in Lancet Infectious Diseases journal.

Additional testing also showed that the man’s immunity system’s ability to fight off other infections remained unchanged and that his immunity system was not damaged by the excessive number of vaccines.
