V-Day has finally arrived: today across Europe the first doses of vaccine against coronavirus supplied by the pharmaceutical company Pfizer-BionTech. The actual vaccination campaign will start from January 2021 and it is expected that in Italy almost half of the entire population can be vaccinated before the summer. The government has repeatedly stated that the vaccine will not be mandatory and in the country there are already those who have said that they have no intention of undergoing the vaccination. But let’s try to understand what is inside the vaccine and why so many people are skeptical of these drugs.
There are many conspiracy theories that we have heard about the coronavirus. Some of them referred to vaccines. In reality, the vaccine ingredients manufactured by Pfizer-BionTech They have been public for some time and their operation is also explained in the informed consent form that will be delivered before vaccination. “The vaccine induces our body to activate a protection mechanism (such as the production of antibodies) capable of preventing the virus responsible for COVID-19 from entering our cells and thus preventing the onset of the disease.“reads the document.
The components of the Pfizer-BionTech vaccine
Which then specifies how the Sars-Cov-2 vaccine contains a RNA messenger that induces the synthesis of virus antigens, which it encodes. These antigens, in turn, stimulate the vaccine’s antibody response by producing neutralizing antibodies. This messenger RNA, again explained in the module, is enclosed in liposomes formed by ALC-0315 and ALC-0159 that facilitate its entry into cells.
The vaccine also contains other excipients:
- 1,2-Distearoyl-sn-glycero-3-phosphocholine
- cholesterol
- dibasic sodium phosphate dihydrate
- monobasic potassium phosphate
- potassium chloride
- sodium chloride
- saccharose
- water for injections
What’s in the coronavirus vaccine
In other words, the coronavirus vaccine contains a piece of messenger RNA that triggers the production of a viral protein in the body where it is introduced. Once this is introduced, the organism recognizes it as foreign and attacks it with a immune response. If the subject to whom the vaccine has been administered comes into contact with the coronavirus in the future, then they will be ready to reject it thanks to the ready-made immune response. This small portion of messenger RNA is injected into the body into lipid nanoparticles, a compound that allows them to be injected into the muscle.
