The Pfizer Covid vaccine uses technology called messenger RNA; see how it works | National newspaper

The coronavirus stopped the planet with its immense capacity for dissemination and extreme aggressiveness.

Inside our body, the coronavirus uses spikes to perfectly adapt to a cell’s receptor. The mechanism works like a key that opens a lock and breaks the cell wall.

Inside, it multiplies very quickly, sucking energy out of the cell. Thousands of new viruses are attacking to destroy other cells.

In fact, our body is constantly on the alert for the thousands of invasions that we suffer all the time. Our immune system, made up of lymphatic cells, begins to react as soon as it is attacked.

Macrophages attack invaders and trigger alarm signals to other defense cells.

This initial barrier is often not sufficient to contain the intruder. A part of our immune system comes into play focused on precisely identifying each invader and attacking it.

Dendritic cells begin work. They are like intelligence experts. They collect pieces of the invader, resulting from the initial battle, and carry them to the T lymphocytes, responsible for communication in the immune system. T lymphocytes activate B lymphocytes and teach them to produce antibodies.

Finally, the molecular weapon ready to defeat the villain that plagues our body is ready.

It turns out that this whole process can take a long time and when the antibody is finally ready, the disease may have advanced a long way, becoming irreversible.

That is why the vaccine is essential. It will awaken our immune system and anticipate the process of producing antibodies. Since the beginning of the pandemic, more than 100 groups of scientists from around the world have dedicated themselves to the search for the vaccine.

The vaccine produced by Pfizer with BioNTech uses the technology called messenger RNA, different from the traditional ones.

In that case, the vaccine carries a copy of part of the genetic code of the virus to our body. It is a kind of message, a recipe for our body to produce a protein from the virus. The presence of this protein triggers the production of antibodies.

It saves time that can be decisive in this life and death struggle. If the vaccinated person becomes infected, they will have an army of antibodies ready to neutralize the crown, preventing it from multiplying.

Only the vaccine can give us the feeling that the life we ​​knew is recovered. Finally, it will be the return of hugs.
