That appears to just be a license to manufacture it, probably under agreement with Pfizer...
They approved a new vaccine under a different law ( BLA) called Cominarty ( the name of the new Pfizer vaxx)
but the old one ( PFizer BioNTech) was not approved. Only kept in “emergency use” until enough of the “new approved vaxx” is available.
It is designed to word play their way out of trouble. In the first paragraph it goes on to say the BLA cominarty is just a revision to the EUA (WHICH IS NOT APPROVED)
These lunatics want to please their masters, and escape culpability all in one to avoid being hanged I am guessing.
