Its hard to understand your argument: Pfizer monopolized the US vaccine market until the end of the lockdown as I said:
> In the beginning of the COVID-19 US epidemic in March 2020, sweeping lockdowns and other aggressive measures were put in place and retained in many states until end of August of 2020
> Moderna in early 2021
You will notice that date is later than the lockdown end date.
By summer 2019, Europe had around 5-6 different vaccines available. The US had only Pfizer. It remained like that until the end of the lockdown.
