Professor Bizzarri’s explanations: “There is no scientific evidence to prove it, but not even elements that can exclude such a connection”
Although today more and more people are recovering and can return to their normal lives, tumors are among the worst diseases one can suffer from. Although physical activity has a protective effect and is useful even after diagnosis, even professional athletes can fall victim to it. Well-known cases are those of Acerbi, who saw his career take off after his recovery and is now experiencing a second youth at Inter, and Haller, who has just led Ivory Coast to win the Africa Cup of Nations. Someone has claimed that mRNA vaccines, such as those used to protect against Covid 19, favor the development of tumors. Let us try to clarify this with Professor Mariano Bizzarri, director of the Systems Biology Lab at the Department of Experimental Medicine of the La Sapienza University of Rome.
Doctor Bizzarri, is there a relationship between mRNA vaccines and tumors?
“At the moment there is no solid scientific evidence to prove this, but not even elements that can exclude such a connection with certainty. In theory, any mRNA, including those found in foods and bacteria, can insert themselves, in whole or in part, into DNA and, in the long run, have carcinogenic consequences. In general, from in vitro studies it can be established with good certainty whether or not a compound has mutagenic capabilities, however it is not obvious that a potentially mutagenic compound is automatically carcinogenic. In the laboratory, possible DNA damage can be observed, which is important especially when it involves certain genes, but it takes a long time to establish actual carcinogenicity. From some studies carried out so far, elements are emerging that suggest that mRNA vaccines trigger some potentially carcinogenic mechanisms, but to have scientific certainty, further confirmation and studies specifically aimed at this purpose are needed”.
To date, therefore, there are no certainties.
“No, and that is precisely why prudence is needed. The epidemiological data available are in fact still not very significant. It is also difficult to understand to what extent the increase in the mortality rate of tumors seen in recent times can be linked to mass vaccination against Covid 19 rather than to the decrease in screening checks witnessed during the pandemic. Establishing a certain link is very complex, as cancer is a multifactorial disease and weighing the importance of each single factor is a difficult undertaking, also because each individual is different from the others. However, myocarditis and autoimmune reactions are recognized as possible side effects of mRNA vaccines, which in reality are nothing more than gene therapies.”
In light of this uncertainty, who should pay more attention to mRNA vaccines?
“People who already suffer from cancer should be particularly careful, as these vaccines can accelerate its evolution, encourage relapses or make silent forms latent. Since mRNA vaccines increase the activity of the immune system, greater precaution is needed even in children. In fact, in this phase of life the immune system normally works well and does not need ‘accelerations’, otherwise there is the risk that its activity becomes excessive. On the contrary, the natural defenses of the elderly are often less efficient, so even by giving them a ‘boost’ with an mRNA vaccine, the risks of hyperactivity are limited.”
