Doctors say that a 62-year-old German man was immunized 217 times against Covid despite medical advice.
The odd instance has been documented in The Lancet Infectious Diseases publication.
The shots were purchased and administered privately over the course of 29 months.
The man appeared to have experienced no harm, according to researchers at the University of Erlangen-Nuremberg.
‘Very interested’
“We learned about his case via newspaper articles,” Dr Kilian Schober, from the university’s microbiology department, said.
“We then contacted him and invited him to undergo various tests in Erlangen. He was very interested in doing so.”
The man gave fresh blood and saliva samples
The researchers also analyzed some of his preserved blood samples from recent years.
In the NHS study on COVID-19 vaccination, Dr. Schober stated that they were able to collect blood samples when the guy requested an additional immunization.
Dr Schober said: “We were 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.”
The public prosecutor of Magdeburg gathered evidence for 130 of the jabs and launched an inquiry based on the suspicion of fraud, but no criminal charges were filed.
Covid vaccinations do not induce infection, but they can train the body how to fight the disease.
mRNA vaccines target the immune system by exposing cells to the virus’s genetic code.
If they come into contact with COVID-19, their immune system should recognize it and know how to resist it.
Dr. Schober was concerned that repeatedly boosting the immune system could have tired specific cells.
However, the researchers discovered no evidence of this in the 62-year-old.
And there was no evidence he had ever been infected with Covid.
‘Favorable approach’
According to the researchers, “Importantly, we do not endorse hyper-vaccination as a strategy to enhance adaptive immunity.”
And the findings of their testing on the 62-year-old were insufficient to draw broad conclusions, let alone suggestions for the wider public.
“Current research indicates that a three-dose vaccination, coupled with regular top-up vaccines for vulnerable groups, remains the favored approach,” they say on the university’s website.
“There is no indication that more vaccines are required.”
The NHS says Covid vaccines are typically given seasonally, but certain patients with a severely impaired immune system may require additional protection at other times – and it will contact those whose NHS records indicate they may be eligible.
Covid vaccinations can cause negative effects. A common one is a painful arm after the injection.
