Here’s the real reason Comirnaty is not available-It’s all about liability. It will magically become available when the vaccine for children is fully approved, not before.

The reason Comirnaty isn’t available is because those shots would expose the company to liability since the fully-licensed product doesn’t have the liability waiver of the EUA product.

But once the Pfizer vaccine is fully approved in kids, then Pfizer gets liability waiver on all age groups due to a “feature” in federal law for child vaccines (NCVIA). At that time, they are done. They can market the COVID vaccine products under full approval for all age groups and face no liability when it kills or disables you. 

This is why they are focused on the kids. This is why there is a reformulation at a 1/3 dose and they changed the buffer and the storage conditions (low temperatures not required). All of these will weaken the protection, but result in a safer vaccine (since it is ineffective). 

So at the end, Pfizer gets a fully approved vaccine with full liability protection. At that time, then the NIH can recognize other treatments.
