A man who received 217 COVID-19 vaccinations has offered himself for a research study investigating the effects of excessive vaccination on the immune system.
What Happened to the Man Who Took 217 Doses of COVID-19 Vaccine?
In March 2022, German authorities detained a 62-year-old man believed to have received over 90 doses of COVID-19 vaccine to amass vaccination cards for resale.
Although no legal charges were pressed, researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg seized the opportunity to study the case and understand the effects of numerous COVID vaccinations on the immune system.
A woman receives a dose of Comirnaty Omicron XBB 1.5 Pfizer vaccine for COVID-19 at a pharmacy in Ajaccio, on October 5, 2023, during a new COVID-19 vaccination campagin on the French Mediterranean island of Corsica.
The study, conducted in collaboration with Universitätsklinikum Erlangen, aimed to determine the consequences of hypervaccination, a phenomenon wherein individuals receive excessive vaccine doses.
Previous speculation suggested that immune cells might become less effective after repeated exposure to antigens. However, the study's results, published in Lancet Infectious Diseases, contradicted this notion.
Fully Functional Immune System
The individual who claimed to have received 217 vaccine doses for personal reasons exhibited a fully functional immune system. Notably, his immune response surpassed that of individuals who had received only three vaccinations.
"The number of memory cells was just as high in our test case as in the control group," Katharina Kocher, one of the study's lead authors, said in a statement. "Over all, we did not find any indication of a weaker immune response; rather, the contrary."
While more than 60 million Germans have been vaccinated against COVID-19, this unique case offered researchers an invaluable opportunity to explore the effects of extreme hypervaccination.
The findings revealed a high presence of T-effector cells combating SARS-CoV-2, surpassing those in the control group of people who have received three vaccinations. Fatigue was not observed in these cells, maintaining effectiveness similar to the control group.
Memory T cells, essential for replenishing effector cells, exhibited similar levels in the individual and the control group, indicating a robust immune response. Notably, the 217th vaccination significantly increased SARS-CoV-2 antibodies.
Further assessments affirmed the immune system's resilience against other pathogens, suggesting no adverse effects from hypervaccination.
"Our test case was vaccinated with a total of eight different vaccines, including different available mRNA vaccines... The observation that no noticeable side effects were triggered in spite of this extraordinary hypervaccination indicates that the drugs have a good degree of tolerability," Dr. Kilian Schober from the university's microbiology department said in the statement.

Comprehensive Conclusions Are Still Premature
However, caution was issued due to the study's singular focus. According to the researchers, comprehensive conclusions or recommendations for the public are still premature.
"Current research indicates that a three dose vaccination, coupled with regular top-up vaccines for vulnerable groups, remains the favored approach. There is no indication that more vaccines are required," Schober said.
The study's findings were published in the journal The Lancet Infectious Diseases.
