Facts: People who make this claim generally base their argument on the supposed similarity between the coronavirus’s so-called spike protein, which the pathogen uses to attach itself to human cells, and the body’s own protein called syncytin-1.
In women of childbearing age, Syncytin-1 is responsible for the formation of the placenta, which supplies nutrients to the offspring in utero. The thesis: An immune defense against the peak corona protein extends to syncytin-1 and thus prevents the formation of the placenta.
However, there is absolutely no particular similarity between the two proteins, so “a vaccine cross-reaction is basically impossible,” says Annette Beck-Sickinger, head of the biochemistry and bioorganic chemistry research group at the University of Leipzig. .
And even if they did, Covid disease should have had harmful effects on pregnant women. In studies on Sars-CoV-2, however, no increased number of miscarriages or complications were found.
Evaluation: That is impossible.
Facts: Today’s vaccines, such as flu vaccines, generally contain killed or weakened viruses or parts of them. The Biontech and Moderna corona agents work differently, that is, for the first time through so-called mRNA (the “m” stands for “messenger”, “RNA” for “ribonucleic acid”).
No dead Sars-CoV-2 pathogens are injected, just the instructions for a component of the virus: the mRNA of the messenger molecule. On this basis, the body’s cells themselves produce parts of the virus envelope protein (spike protein). Faced with this, in turn, the immune system now develops certain factors so that in case of subsequent contact with the coronavirus it can recognize the structure of the protein and specifically defend itself against the pathogen.
Information from RNA cannot be incorporated into human DNA. That already prevents the different chemical structure of both. Furthermore, the mRNA ingested with the vaccination does not even reach the cell nuclei where the genetic material is stored in the form of DNA.
Facts: 43,448 people participated in Biontech’s phase 3 study. In the study period from late April to mid-November 2020, six of the participants died, but not from vaccination.
“All the deaths represent events that occur at a similar rate in the general population of the age groups in which they occurred,” writes the FDA, the agency responsible for approving the drug in the United States. The European approval authority EMA sees “no connection” between the cases and the vaccination study: “It is more likely that previous diseases were the cause of death.”
Facts: Unlike Britain and the US, for example, there was no emergency license in the EU, nor in Switzerland. Instead, Europe and Switzerland depend on conditional market approval. The difference: in the case of a conditional marketing authorization, testing is carried out more extensively and manufacturers are more responsible for the safety of the medicine.
In light of the pandemic situation, the approval process for corona vaccines has accelerated; the so-called continuous review process applies. Manufacturers of pharmaceutical products can submit individual reports on the quality, safety and efficacy of their preparation prior to the full application for approval, rather than at the end. This makes the process faster, but no less secure.
Although none of the mRNA vaccines have been previously approved for humans, the technology was not only developed in the wake of the corona pandemic. Research has been done for more than three decades, for example, for cancer therapy and vaccines against rabies, Zika, or seasonal flu. Corona just gave the mRNA process the breakthrough.
