CSL Biotherapies starts U.S. shipments of influenza vaccine.

First shipments arrive for the 2007/2008 season

KING OF PRUSSIA, Pa. -- CSL Biotherapies, a subsidiary of one of the world's leading manufacturers of influenza vaccine, announced today that it has begun shipment of its influenza virus vaccine in the United States for the 2007-2008 season.

Coming after expedited approval by the United States Food and Drug Administration (FDA) of the inactivated, trivalent vaccine, shipping includes both single-dose, thimerosal-free, pre-filled syringes and multi-dose vials, to provide choice and convenience to caregivers who administer it.

The company will make approximately two million doses immediately available to the U.S. market for the 2007/08 season.

"CSL Biotherapies, with a 40-year heritage in influenza vaccines worldwide, is committed to helping address a priority public health goal in the U.S. by providing a reliable supply of high quality flu vaccine, including a thimerosal-free formulation," said Paul Perreault, Executive Vice President of CSL Biotherapies Worldwide Commercial Operations.
