> Only you can't get it anywhere and BioNTech is considered legally distinct
Which is interesting for some very esoteric legal reasons, but even to the extent that a formulation only allowed for non-investigatory use under an EUA rather than normal approval might approximately be said to be “experimental” (which is a fairly weak argument itself), the Pfizer-BioNTech COVID-19 Vaccine, which is an identical formulation to the fully-approved Cominarty, but legally distinct because packaging is legally significant in drugs and biologics, would still not be “experimental”.
