A 62-year-old German man received 217 COVID-19 vaccinations, according to a study published in The Lancet Infectious Diseases, reported the BBC.
The man, who has not been identified, was investigated by prosecutors for fraud after it was discovered that he had received multiple vaccinations from different doctors and vaccination centres.
Researchers from the University of Erlangen-Nuremberg contacted the man and invited him to undergo a series of tests to examine his immune response.
The tests showed that the man's immune system was functioning normally and that he had high levels of antibodies against SARS-CoV-2, the virus that causes COVID-19.
The researchers also found that the man had not experienced any negative side effects from the multiple vaccinations.
"We were surprised to see that the man's immune system was not exhausted," said Dr. Kilian Schober, one of the authors of the study. "In fact, his immune response was stronger than we would have expected."
The researchers say that the man's case is an outlier and that it is not possible to draw any general conclusions from it. However, they say that the findings suggest that it is safe to receive multiple COVID-19 vaccinations.
"Our findings support the current recommendations for booster vaccinations," said Dr. Schober. "They also suggest that it is safe to receive multiple COVID-19 vaccinations, even in people who have already been infected with the virus."
The man told the researchers that he received the multiple vaccinations for personal reasons. He said that he was concerned about the safety of the vaccines and that he wanted to protect himself from COVID-19.
The researchers say that the man's case highlights the importance of public education about COVID-19 vaccines.
"It is important for people to understand that the COVID-19 vaccines are safe and effective," said Dr. Schober. "They are the best way to protect yourself from the virus."
