Be wary of fine details. They do not say that the EUA version and the Cmirnaty version are identical. They say that there are minor differences that do not matter. Now, the EUA version has no package paperwork declaring the composition. There is no legal liability. There is no way they can be held to any standard of faithful product definition, representation, and production. The Comirnaty version is supposedly only different in ways that do not affect safety or effectiveness. How in Hell can that ever be substantiated if you do not have a legally verified composition for the EUA version? Moreover, it is not sufficient to have paperwork alleging the composition. You have to have an assay of the actual substance to see WHAT IT IS, not what it is SUPPOSED TO BE. (In my line of work, we get annual training on the importance and seriousness of "product substitution" violations.)

All these assurances are worthless. And this is not even touching the issue that the EUA version has no legal liability and the Comiraty version is supposed to have legal liability.
