DEERFIELD, Ill. - Specialty drug maker Baxter International Inc. says it's in "full scale" production of an H1N1 flu vaccine that will be commercially available in July.

The company based in Deerfield, Ill., made its announcement Friday, a day after the World Health Organization declared swine flu a global pandemic.

Baxter has said that its patented technology cuts in half the usual time it takes to develop a vaccine -- to about 13 weeks instead of 26.
