This is my understanding of what the FDA did.

They muddied the waters to give the appearance of giving full FDA approval to the Pfizer jab, without actually doing it.

On the same day they both extend the Emergency Use Authorization for the Pfizer Jab that we all know and (do not) love, and they say they have full approval of another Pfizer product called Comirnaty, which is a different product that is the same thing.

Why didn't they offer their approval for the Pfizer jab that everybody has been taking? Why only this other product with a different name?

Because along with the Emergency Use Authorization comes legal liability for Pfizer. It doesn't matter if it kills you instantly when it is injected. Your family will not be able to hold Pfizer liable.

Comirnaty does not have this legal shield for Pfizer. But Pfizer isn't worried because they have no intention of manufacturing it or giving it to anybody. They gave it a name that is very hard to remember and spell properly. It exists only to support the notion that the Pfizer jab is now FDA approved.

The FDA doesn't have to worry about the consequences of bypassing all their normal procedures, because Comirnaty will never be given to anybody.
