From the Edmonton Sun:
At-risk people go first in line for flu shots
Some 75 private flu clinics in the city have been cancelled because of increased public demand for vaccinations. The Victorian Order of Nurses, which scheduled the Edmonton clinics, had to cancel clinics in private pharmacies like Costco Wholesale because Canada's two suppliers have to immunize more at-risk patients than in previous years.

VON has contracts with pharmacies to provide the vaccine to people that aren't in the high-risk group.

"The government is making an effort to get at-risk people the vaccine. The people that we were doing are healthy," said Sheri St. Arnaud, VON's city clinical co-ordinator.
