The FDA contradicts you and states that legally they are two different vaccines:

In this letter the FDA states that the mRNA Comirnaty COVID-19 Vaccine, is the same formulation as the Pfizer-BioNTech COVID-19 Vaccine except "The products are legally distinct..." See https://www.fda.gov/media/150386/download


No, they do not. You're misunderstanding what the FDA means by "legally distinct." They are not chemically or pharmacologically different. The difference is merely a legal one. The stuff in the vials is exactly the same stuff, but the vials have to be tracked and described separately because of legal requirements.

Vaccines, like most medicines, are manufactured in batches. Pfizer has been manufacturing the covid vaccine pretty much continuously under the emergency authorization for many months now. They don't just manufacture 150 million doses at once - they will manufacture some amount of vials on one day, more vials on the next, and so on. They'll manufacture vials of vaccine on Monday, and then using the exact same process and materials they'll manufacture vials of the exact same thing on Tuesday, and then again on Wednesday. It's the same vaccine in each batch of vials.

All that's happened is that from day to day making the exact same vaccine, the regulatory status of the vaccine changed. Monday's output of the vaccine was manufactured under the EUA, and was placed in vials identifying it with the EUA approval number and other identifying information relating to that approval status. Tuesday's output of the exact same vaccine was issued under the FDA approval status, and placed in vials identifying it with the FDA approval for Comirnaty and other identifying information.

It's the exact same vaccine, no different from prior batches than any other batch of the vaccine is from prior batches. However, because it was manufactured and labelled under a different legal environment and regulatory status, all of the folks in the chain of administering it are required to treat the unlabeled vials separately from the Comirnaty vials. They are legally distinct, but biologically and medicinally identical.

A number of vaccine critics have chosen to misrepresent what the FDA's announcement means. It's not hard to find out that all of these doses are the exact same vaccine, and that different batches of that same vaccine are being treated differently solely because of the regulatory legalities. Heck, it's in the same materials you cited. But by willfully misunderstanding what the FDA means by legally distinct, they can create misunderstanding in other people.
Hopefully this has clarified to you what the FDA means, and that there is only one vaccine which has now been approved by the FDA for people 16 and older.
