CHICAGO (AP) - Uncertainties over vaccine supply and demand dominated a two-day brainstorming session for the upcoming flu season, where public health officials and manufacturers discussed ways to avoid a crisis like last year's shortage.
So far, only one manufacturer is licensed to provide shots in the United States for the upcoming season.
Two others said Wednesday they are making progress at entering the marketplace — including Chiron Corp., whose contamination problems last fall at a factory in Liverpool, England, left the United States with half as much flu vaccine as anticipated.
