I said I was waiting for the comfort of science to get the vaccine. There was consolation and here I am getting vaccinated. He sighs, sits up, rolls up his shirt sleeve, looks away, and lets the doctor proceed with the needle and the dose of Pfizer. After the numerous controversies, which have seen it displayed in front of the skeptics due to lack of data, the microbiologist Andrea Crisanti has said yes to the injection of anticovidio. A scene filmed live on Facebook and presented by the Medical Director of the Padua Hospital, Daniele Donato: I present our testimony. As if to say, twist, for the institutions and for the public and if it does you can trust it.
Transparency problem overcome
Before the puncture, Crisanti explained his reasons: There was a transparency problem, which was later solved with the exchange of data, between the scientific community and the public. So I think the time has come to witness the turning point. We have vaccines available that are safe. There are several types. The first are those of Pfizer and Moderna. These are RNA vaccines.
How does it work
What is RNA? the virus instruction manual, we must imagine it as a tape that reproduces the virus and begins its cell multiplication activity – explained Crisanti technically – The vaccine is a piece of this tape and contains only the information useful for the immune system is activated . So when a person encounters the virus, the immune system is primed and neutralizes it. This is the Pfizer vaccine that I am going to get right now.
The three generations
And it explains the differences compared to the others: Similar modern but with stabilizer does not need the ultra-cold chain and therefore from a logistical point of view it is easier to distribute. Other vaccines will follow, such as Astrazeneca, which has a viral vector, which is a harmless virus within which is again a piece of genetic information, which will be rotated and opened for the immune system to react. And then there will be third-generation vaccines, based on virus proteins. These will have information already translated, whereas here the information is translated by our cells. In other words, there are three types of vaccines that we will have in sequence, a sequence that is necessary because they have different manufacturing complexities. But these are technological differences. The important thing is that the proteins of the virus stimulate the immune system.
Arm pain, fever, allergies – don’t worry
Crisanti said it clearly: We are facing a harmless vaccine. So of course it could be that someone develops some arm pain. There may also be some fever. They say that there may be allergic reactions. I want to reassure everyone: for example, I am allergic and I do, also from this point of view, so do not be afraid.
In short, a never-before-seen Chrysanti, definitely reassuring and s-vax. It is an important moment. I hope there is maximum adherence, which is essential to block the chain of transmission of infection. I’m glad you are on our staff in the meantime. It is a testimony of trust and at the same time an example for all. I stop here.
Here stops the testimony, a little painful, of the professor.
