That’s not exactly the way it is. Think of the USA as a collection of states, each with a constitution and distinct sovereign rights.
Each state is responsible for the response inside their borders. Vaccine distribution is a state thing, not a federal thing.
Aldo know that as of early Feb, the US had distributed and delivered more jabs every day than Canada has delivered in total. Over 50 million jabs delivered in the US so far vs 1.3m inCanada.
The US delivered 1.65 million jabs today, Canada did 18 thousand.
Certainly, no one is claiming that WE don't have our own set of problems with this!
I'm sure we'd be delivering more, if we could actually get our hands on it, or (gasp) make some within our own borders ...
And just because the individual states are responsible for what they do internally, doesn't mean you can't have a great big conference call to co-ordinate and organise things, and make sure that if the states require any additional federal resources, that they get it.
