U.S. won't likely seek Canadian flu vaccine
It's looking less likely that the United States will be turning to Canada to help ease the shortage of flu vaccine, despite comments earlier this week by U.S. President George Bush.

Canada's supply of flu vaccine has been recently thrust into the international spotlight, after pharmaceutical company Chiron Corp. announced it wouldn't be able to deliver on a U.S. order for 48 million doses.

The order couldn't be delivered, the company said, because British regulatory authorities suspended the operating licence of the Liverpool plant where the vaccine was made. Contamination problems were cited as the reason.
