Formulaically they SHOULD be the same.
However…
The brand name version is the one you can sue Pfizer for adverse reactions for - the other is still under EUA law.
The one that has a name like Comirnty, is the approved poison.
You are incorrect on both counts.
The two “vaccines” can be used interchangeably and they possess indemnification after approval. One can only sue the government, not Pfizer.
PREP act immunity does not depend on FDA approval.
Read the PREP act and the PREP act declaration
“Covered Persons who are afforded liability immunity under this Declaration are “manufacturers,” “distributors,” “program planners,” “qualified persons,” and their officials, agents, and employees, as those terms are defined in the PREP Act, and the United States. “
“A qualified pandemic or epidemic product means a drug or device, as defined in the FD&C Act or a biological product, as defined in the PHS Act that is (i) manufactured, used, designed, developed, modified, licensed or procured to diagnose, mitigate, prevent, treat, or cure a pandemic or epidemic or limit the harm such a pandemic or epidemic might otherwise cause; (ii) manufactured, used, designed, developed, modified, licensed, or procured to diagnose, mitigate, prevent, treat, or cure a serious or life-threatening disease or condition caused by such a drug, biological product, or device; (iii) or a product or technology intended to enhance the use or effect of such a drug, biological product, or device.”
“To be a Covered Countermeasure, qualified pandemic or epidemic products or security countermeasures also must be approved or cleared under the FD&C Act; licensed under the PHS Act; or authorized for emergency use under Sections 564, 564A, or 564B of the FD&C Act.”
It’s as clear as can be. Covered Countermeasures include:
FDA Approved products.
OR
Licensed Products
OR
EUA Products.
And the EUA version is the one you can sue your employer for mandating.
