This thing started because of the added restriction of being fully vaccinated to cross the US or Canadian border as a trucker.
The vaccine vastly reduces rates where people end up having to be hospitalized, and hospitalization is expensive and bad.
Shouldn't be a problem in a free market. Supply will increase in response to increased demand and prices will adjust accordingly in the interim. It will be fine. Not the government's job to micro manage this stuff, especially by trampling on fundamental individual rights.
