Endocrinologist and biologist address one of the biggest fears about vaccines
Last week I had stream with Maxim Bokov, biologist (Moscow State University), biophysicist, PhD, scientist at Charles University (Prague).
I begin to slowly spread the most interesting from there.
- Commoners are very worried that vaccination can change human genes. I do not know what anti-vaccines are afraid of, but clearly not that someone will become blue-eyed blond if he was previously a brunette. Can any negative changes occur or not?
- No. Neither Sputnik, Pfizer, Moderna, nor any other coronavirus vaccines are inactive. They do not have the ability to integrate into the human genome and change it.
Changing the genome requires a very complex system of special “building blocks” and proteins that will help the vaccine integrate into the human genome.
In 2012, an article was published about the opening of the system CRISPR-Cas. These are molecular scissors that genetic engineers use to cut and insert parts of a gene. This system has been found in bacteria. That is, these microorganisms are engaged in editing the genome without human intervention.
So, if we talk about these vaccines, then they do not have such a system. And even theoretically, they cannot change our genes.
Can the coronavirus itself change genes?
Initially, there was a hypothesis that the coronavirus itself could be inserted into the human genome. But then it was refuted.
- The mentioned CRISPR system is, of course, a brilliant piece. High hopes are pinned on it in relation to herpes and other viral infections that are found in the nervous tissue. The drugs only act on them when the virus is active. But with the help of the CRISPR system, it may be possible to reach the inactive, dormant virus and with these scissors deprive it of the opportunity to harm a person.
- Bacteria, in principle, protected themselves from viruses. That is, until 2012, scientists thought that bacteria had no defense against viruses (roughly speaking). And then it turned out that there is immunity, and this is how it works.
To be continued.
