Three letters and four numbers to spread the umpteenth hoax about vaccines online. One in particular, that of Pfizer and BioNtech, guilty of having produced a vaccine containing an excipient harmful to our health: Alc-0315.
To launch the hoax that immediately became a social ‘narrative’ in the service of No Vax was Francesca Donato, the former member of the League which has always been opposed to the Covid vaccine.
How are things really? Who to believe? Two anti-hoax sites, Facta News and Bufale.net, have already dealt with the issue in recent days, clearly denying the news. To further clarify how things stand, we interviewed the professor Filippo Drago, director of the Clinical Pharmacology Unit of the University Hospital of Catania and member of the task force for Covid-19 of the Italian Society of Pharmacology.
What is Alc-0315
As can be read from the official company documents, the Comirnaty vaccine actually contains this substance. What is it about? “They are synthetic lipids that are used to incorporate the mRna which is then used for the formulation of the vaccine and which serves to facilitate its entry into the cells”, explains Drago who adds: “A lipid of the all similar “.

The request for clarification of the EMA
According to the hoax that is circulating on the Net, Pfizer would have chosen to focus – in full awareness – on an element that is harmful to us. But can the excipient in question really be harmful to health? “Both Alc-0315 and the other excipient Alc-0159 of the Pfizer vaccine are used in absolute safety, so much so that it is a component that we also find in other vaccines such as that for rotavirus and malaria”, reassures the pharmacologist. reference to a document from the National Center for Biotechnology Information.
The doubts relating to the safety of this substance, however, date back to July last year, when the EMA had made a request for clarification on its harmlessness to Pfizer since it is an excipient considered new. “The European regulatory agency – says the expert – then declared last December that it had received all the necessary information about the safety of the lipid excipients of the vaccine and in particular about the Alc-0315″.

The idea that there was also a conspiracy on the use of the excipient was ‘built’ starting from a document of the biotechnology company Echelon Biosciences Inc. which describes the product in question as the result of work intended for research and not safe for the human use.
The confusion is more than justified: “The materials and therefore also the excipient Alc-0315 that Echelon Biosciences Inc. produces and sells are intended only for laboratories”, explains Drago. “When sold as laboratory products, the substances do not have as rigorous processing and quality control as is required when the product is sold for human use. This is precisely why the excipient in question is defined on the Echelon site. as a product intended for research only and not for human use “.

The vaccine’s Alc-0315 is not Echelon’s
But to understand the question, a piece is still missing: “It is very likely that Pfizer does not purchase the excipient Alc-0315 contained in the vaccine from Echelon, especially since it is intended for laboratories and markets it not in its pure form, which is completely harmless for the vaccine. man, but in a solution of chloroform and ethanol, actually carcinogenic substances “, explains Drago.
In short, the excipient contained in the vaccine could be purchased from another supplier especially since as can be seen from this document of the National Center for Biotechnology Information there are 12 producers of the same substance.
To confirm the fact that the excipient used in the anti-Covid vaccine is not the one produced by Echelon is the same biotechnology company that in a statement declares: “… the material that Echelon Biosciences is producing and selling is not used in the production of vaccines but only for research use in laboratories. When sold as laboratory products, the manufacturing processes and safety tests do not have to be as rigorous as when the same product is given to people. This is why we state our site that the material we make is intended for research only and not for human use, but this is not a claim that Alc-0315 and Alc-0159 are unsafe. “
