The "flut shot" issue.

So is it just that Americans are nicer to flu vaccine manufaturers? Or do they pay more for their shots? Why is it they are getting their flu shots on time, and those of us in Canada have to wait because of a delay in production.

Does the company think that maybe American lives are more important? Perhaps it is an American company producing all these shots? I suppose last year it was the Americans who were delayed. I just don't understand this discrepency.
