(Nasdaq: MEDI) and Henry Schein (Nasdaq: HSIC) announced today that Henry Schein has been selected as the exclusive U.S. distributor of MedImmune's FluMist(TM) (Influenza Virus Vaccine Live, Intranasal) for the upcoming flu season. MedImmune, which has exclusive rights to manufacture and market FluMist, will oversee all sales and marketing activities with special emphasis on pediatricians and pharmacies. In addition to selling FluMist, Henry Schein will respond to customer product inquiries, process returns, and promote the product through marketing initiatives to primary care physicians.

MedImmune also announced today that it has substantially reduced the price of FluMist to approximately one-half of what the vaccine was available for last season. Henry Schein will sell FluMist to physicians and pharmacies for $23.50 per returnable dose.

FluMist will be available through Henry Schein, as well as its Caligor Medical and General Injectables & Vaccines (GIV) businesses. Effective immediately, Henry Schein and its subsidiaries are ready to take orders for FluMist for the upcoming flu season. Henry Schein typically begins shipping flu vaccines in late summer.

"As an important new option in the ongoing fight against the most frequent cause of death in the United States from a vaccine-preventable disease, it is important that healthcare providers include FluMist in their arsenal of flu- prevention options for their patients," said Armando Anido, R.Ph., senior vice president, commercial operations, MedImmune, Inc. "Along with MedImmune's industry-leading pediatric sales and marketing team, Henry Schein is uniquely suited to reach the large and diverse community of healthcare providers who administer flu vaccinations in the United States."

"The ability to offer FluMist is consistent with our commitment to meeting the needs of our healthcare provider customers," said Michael Racioppi, R.Ph., president, medical group, Henry Schein. "Our hope is that with the availability of FluMist -- the first innovation in flu prevention in over 50 years -- even more people will receive a flu vaccination."
