“It cannot be infected because it does not contain the virus”

Professor Răzvan Cherecheş, from Babeş-Bolyai University in Cluj-Napoca, wrote on Facebook Saturday night that he received several questions about how the messenger RNA vaccine from Pfizer and Moderna works and explained in some extremely simple and fun way.

“Our immune system takes care of any foreign body that enters the body. If our body encounters a protein, a virus or a bacterium that it does not recognize, it launches an attack. If it is fighting a virus, it needs time to launch an attack You need to find out which part of the virus can attack you and start producing weapons to attack that part. This may take a few days. Meanwhile, the virus spreads and multiplies. Once it has defeated a virus, our immune system does so. remember, “says Professor Cherecheş.

It states that the immune system has “memory cells” and remembers when it encounters the enemy.

“Our immune system has some memory cells that, if they find the same virus again, they announce it . Our immune system uses previous experience to destroy the virus before it makes us sick. The COVID virus has a protein on the outside that helps it enter our cells more easily (makes it more infectious). This protein makes COVID an even bigger bastard – it’s a vicious protein. The virus has RNA, the genetic information that encodes all the activity of the virus. The researchers decoded all the RNA from the virus and found the section that has the production instructions for the vicious protein, “says Răzvan Cherecheş.

According to the UBB professor Cluj, the Pfizer and Moderna vaccine contains only the RNA fragments that contain the production instructions for the “vicious protein”.

“So we cannot get infected with the vaccine, because it does not contain the virus. Once vaccinated, our cells receive RNA fragments with production instructions and say . Once the vile proteins have been produced, the RNA segments are destroyed (like the IKEA assembly instructions – you don’t need them once you’ve assembled the cabinet). So our cells produce a lot of vile proteins (which don’t have a virus nearby to help them get into cells). Our immune system sees vile proteins floating aimlessly and says and begins to attack proteins. When you meet them for the first time, you need a few days to launch a full attack, “says Cherecheş.

According to Răzvan Cherecheş, fever, chills and muscle aches are just the outward signs of the immune system’s attack on “vile proteins.”

“After our immune system has destroyed all the vile proteins, the memory cells remember exactly how they are destroyed. At this point, there is nothing left of the vaccine, just the memory cells’ memory of exactly how the proteins are destroyed. At some point, a COVID virus enters our body. Our immune system hasn’t seen it yet, but since the virus is wrapped in a vile protein, our immune system says . Our immune system immediately launches an effective attack (memory cells know exactly how to do it) and destroys proteins and the virus before it has time to reproduce. Congratulations, you are protected by COVID-19 ”, writes the professor at UBB Cluj.
