Australia had 14,703 confirmed cases of swine flu as of Wednesday, and at least 41 deaths, according to the AP. The winter flu season is well under way in the Southern Hemisphere.
Both companies said it would be at least six weeks before results of the initial trials are known.

As was the case when the H1N1 swine flu virus first surfaced in Mexico and then the United States in mid-April, infections in the Southern Hemisphere continue to be relatively mild, much like the seasonal flu, and recovery is fairly quick.

Seasonal flu typically surfaces in late fall.
Unlike seasonal flu, the H1N1 flu continues to pose more problems for younger people, Schuchat added. "There are higher attack rates and hospitalizations in yo
