I seriously doubt Pfizer had a choice in how to market the vaccines. I bet governments imposed their rules or else.

And that is how we ended up with the completely f'ed up allocation where in the beginning elder folks completely isolated from the virus had priority while active, exposed younger persons did not have access.

Central planners have failed over and over again to allocate resources as needed in the territory, while a market-based approach will simply and elegantly solve this problem while maximizing the incentives for producers.
