PSS WORLD MEDICAL COMMENTS ON INFLUENZA VACCINE
DELIVERY TIMING AND AVAILABILITY

Jacksonville, Florida (August 27, 2004) – PSS World Medical, Inc. (NASDAQ/NM:PSSI) today commented on the delivery timing and availability of the influenza virus vaccine, Fluvirin®, which is manufactured by Chiron Corporation.

        The Company anticipates that it will deliver and bill its sales of influenza virus vaccine in the third quarter of fiscal 2005.

        In a press release issued yesterday, Chiron Corporation announced that, in conducting final internal release procedures for its Fluvirin® influenza virus vaccine, the company’s quality systems have identified a small number of lots that do not meet product sterility specifications. While ongoing internal investigations into the root cause of the variance indicate no widespread issues with the manufacturing process, Chiron has delayed releasing any Fluvirin doses until it has completed additional release tests. Chiron currently expects that the additional tests will delay product release until early October.

        David A. Smith, President and Chief Executive Officer, commented, “The Chiron release moves our influenza virus vaccine delivery and sales from our second quarter to our third quarter. We remain committed to delivering on our goal of $0.51 — $0.55 earnings per share for fiscal year 2005.”
