Humans have a significant number of T cells in their body, which contribute to the immune response against Covid-19. However, for scientists, these results should not lead to the formulation of health recommendations.
He said he was getting vaccinated for personal reasons. In a study published on Monday March 4 by The Lancet Infectious Diseasesscientists from the Friedrich-Alexander University of Erlangen-Nuremberg and the University of Erlangen were interested in the case of a 62-year-old German man from the city of Magdeburg (central Germany) who has been vaccinated no less than 217 times against Covid-19.
Scientists wanted to look into the effects of this hypervaccination. They therefore made him undergo blood and saliva tests. “We learned about his case through newspaper articles,” said study leader Dr. Kilian Schober. on their university website.
“We used these samples to determine exactly how the immune system responds to vaccination,” he adds. The man received mainly injections of RNA-messenger vaccine, from several different laboratories.
No weakening of immunity
And the answer is surprising. They noted the presence of a significant number of T cells which contribute to destroying cells infected by Covid-19. Additionally, these cells did not appear to show any signs of fatigue in the immune response.
During their research, the scientists did not find any traces of past infection with the coronavirus. However, these can go back several years and are no longer visible in the body.
However, the authors of the study assure us: they do not approve of the use of hypervaccination to strengthen immunity. “Current research indicates that a three-dose vaccination, combined with regular complementary vaccines for vulnerable groups, remains the preferred approach,” they say.
In addition, scientists point out that a single case does not make many cases, and that the conclusions of this study do not make it possible to formulate recommendations for a broader public.
Certificates resold?
In 2022, the german press mentioned the case of a German national, originally from the same town of Magdeburg, who echoed the story of a 61-year-old man arrested for having received, at the time, 87 doses of vaccine . His idea was simple, obtain as many certificates as injections, then resell them to refractory people.
The man presented himself at different vaccination centers but did not present a health insurance card. In fact, the German authorities could not trace him.
In an article which discusses the study of which it was the subject, the BBC underlines that an investigation has been opened against the man for allegations of fraud, but that no criminal action has yet been initiated.
