Lol, phizer got approval in 8/21 for a vaccine (Comirnaty) that isn't being produced and isn't available. Hopefully they'll start making it available in May, and I'm curious to see how the efficacy fares against the EUA version. Phizer claims the formula is the same and it is only a name change, yet I've yet to find any independent studies that evaluate the contents of the differently labeled vaccines (Biontech is the EUA version).

Go ahead and use Phizer's "Comirnaty Finder" tool on its website if you don't believe me. It's going to come up blank. Kind of bizarre how a vaccine that needed intense refrigeration could be produced in such a large quantity that two years later we're still working through the stuff with the old label...

EDIT: Woops, seems like there's limited distribution of Comirnaty now from when I last checked. I'd have to drive two or three states away to get the FDA approved vaccine, but that's a minor inconvenience to stopping the spread...

Biontech is just the name of the company that created the vaccine, which is called comirnaty even in Europe. On my swiss vaccine certificate it says "Pfizer-Biontech (Comirnaty)" 

Comirnaty was just the name given to the vaccine that was previously called "the Pfizer biontech vaccine" 

It's the same thing
