No, messenger RNA vaccines are not toxic to the human body



A theory circulating actively on social networks assures that the Spike protein present in anti-covid messenger RNA vaccines is “cytotoxic” and therefore dangerous for the integrity of the cells of the human body. Originally worn by Robert W. Malone,
a scientist who presents himself as one of the inventors of mRNA vaccines, this allegation was notably relayed in France by the essayist Idriss Aberkhane on Twitter on Monday.

“When the inventor of RNA vaccines tells you cash that the Spike protein is – obviously – toxic for your cells …”, he laconically pointed out to his 79,000 subscribers by referring to a tweet from Robert W. Malone. In the latter, the professor affirms that “the peak protein of SARS-CoV-2 is cytotoxic”, and that several studies, including one piloted by the Salk Institute, an American nonprofit research institute, would formally demonstrate this.

This allegation was already made by Malone in a video of 15 minutes posted on June 13 on the YouTube channel “DarkHorse Podcast Clips”. Accompanied by two other men, he then ensured that the Spike protein, like vaccines against Covid-19, were “cytotoxic” and “extremely dangerous for the human body”.

FAKE OFF

“We already knew that the Spike protein is cytotoxic, there is nothing surprising about it!, Explains to 20 minutes Morgane Bomsel, research director at CNRS and head of a laboratory at the Cochin Institute. The virus, when it has infected its host, will continuously produce this protein and destroy cells in its path, which is precisely what makes it dangerous. “

“On the other hand, the Spike protein present in mRNA vaccines is modified to reproduce only in small quantities and over a very short period of time, in order to be immediately used by the immune system to defend itself against Covid- 19, she explains. To say that vaccines are cytotoxic is therefore false, not only because RNA does not replicate in organs of the human body, but also because we would, quite simply, have noticed it very quickly after having vaccinated millions of people. . “

What does the Salk Institute study say?

This analysis is not contradicted in the study put forward by Professor Robert W. Malone, which therefore seems to misinterpret its results. In an article published on April 30, 2021, and titled “The spike protein of the novel coronavirus plays an additional key role in the disease”, the Salk Institute summarizes the study published the same day in the scientific journal Circulation Research.

Carried out in collaboration with several other research institutes, including the US National Institute of Health, this study consisted of creating a pseudovirus surrounded by a crown of Spike proteins – “which behave very differently from those safely encoded by vaccines” , notes the institute -, without however containing real virus, then to inject it into hamsters. The latter then suffered damage to the lungs and arteries, again proving the cytotoxic nature of the protein, suggesting that Covid-19 is not only a respiratory disease, but also a vascular disease.

“This could explain why some people have strokes and why others have problems in other parts of the body,” said Professor Uri Manor, co-author of the study. This discovery could thus make it possible, in the future, to develop new treatments against Covid-19.

The study therefore does not prove that anti-Covid vaccines would be dangerous for the human body, it concludes on the contrary that “the antibodies generated by the vaccination and / or the exogenous antibodies against the Spike protein not only protect the host from the disease. infectivity of SARS-CoV-2, but also inhibits endothelial damage [sorte de lésion vasculaire] imposed by the Spike protein. “
