Henry Schein Joins IAVI Corporate Philanthropy Program

NEW YORK – November 29, 2007 – Leading provider of healthcare products and services, Henry Schein, Inc., will provide critical consumable and clinical supplies to support AIDS vaccine research in the UK and Africa, the International AIDS Vaccine Initiative (IAVI) announced today in advance of World AIDS Day. Donating $50,000 worth of products to IAVI’s Human Core Immunology Lab in the UK over the course of a year, Henry Schein joins IAVI’s active corporate philanthropy program, demonstrating how businesses can successfully leverage their core expertise in the area of social responsibility.

“We are pleased that Henry Schein has chosen to partner with IAVI and hope this is the beginning of an ongoing partnership. This generous contribution demonstrates concrete ways in which companies with little or no ties to AIDS vaccine development can contribute significantly to the front lines of AIDS research,” said Seth Berkley, President and CEO of IAVI.

“We are delighted that Henry Schein Cares, our global social responsibility program, is able to contribute to the important work that IAVI is doing,” said Stanley M. Bergman, Chairman and CEO of Henry Schein, Inc. “We strive to support causes that are important to our customers—office-based healthcare providers around the world—and certainly AIDS vaccine research is a priority throughout the medical community.”

IAVI researches and develops AIDS vaccine candidates and conducts HIV clinical trials and clinical research through partnerships with more than 40 academic, biotechnology, pharmaceutical and government institutions. Since its inception in 1996, IAVI and its partners have advanced six vaccine candidates into human trials in 11 countries. Donations from Henry Schein, Inc. will be used to support the immunological testing of blood samples shipped from field sites in Africa, where IAVI is currently conducting AIDS vaccine clinical trials in five countries.

Together with IAVI, businesses can help to further mobilize the political will and drive the scientific progress that is needed to blunt the AIDS pandemic. In addition to Henry Schein, Inc., BD, Continental Airlines, Google, Merck and Pfizer have all partnered with IAVI by providing financial support, scientific talent, equipment, logistical support and increased visibility for AIDS vaccine development.
