ROCKVILLE, Md., Oct 09, 2008 (BUSINESS WIRE) ----Emergent BioSolutions Inc. (NYSE: EBS) announced today that two medical countermeasures included in its anthrax franchise -- BioThrax(R) (Anthrax Vaccine Adsorbed) and Anthrax Immune Globulin (AIG) -- have been included as covered countermeasures under the Public Readiness and Emergency Preparedness Act (PREP Act) pursuant to a declaration issued by the U.S. Department of Health and Human Services (HHS). In issuing this declaration, the Secretary of HHS determined that there is a credible risk that the threat of exposure to anthrax and the resulting disease constitutes a public health emergency. The declaration will remain in effect until December 31, 2015. BioThrax is the only vaccine licensed by the U.S. Food and Drug Administration for the prevention of anthrax infection.

This HHS declaration under the PREP Act provides liability protections to activities related to developing, manufacturing, distributing, prescribing, dispensing, administering and using both of the company's anthrax medical countermeasures in preparation for, and in response to, a potential anthrax attack. In addition to this declaration, in 2006 BioThrax was certified under the Support Anti-Terrorism by Fostering Effective Technology Act (the "SAFETY Act"), which Congress enacted to encourage the development and deployment of anti-terrorism technologies by providing certain liability protections for providers of qualified anti-terrorism technologies for claims arising out of acts of terrorism.

"This PREP Act declaration is further evidence of the U.S. Government's commitment to our efforts to develop a portfolio of medical countermeasures to address the threat to public health posed by the use of anthrax as a weapon of biological warfare," said Daniel J. Abdun-Nabi, president of Emergent BioSolutions. "As a long term supplier of BioThrax to the Department of Defense and the Department of Health and Human Services, and as a developer of new medical countermeasures for the prevention and treatment of anthrax infection, we take very seriously our role in cooperating with the U.S. Government to address this threat."

About Anthrax Immunoglobulin (AIG)

Emergent BioSolutions is developing an anthrax immune globulin (AIG) product candidate as a single dose intravenous therapeutic for treatment of patients with manifest symptoms of anthrax disease resulting from the release of anthrax toxins into the body. If successfully developed, it is expected the AIG therapeutic will be prescribed for administration either as a monotherapy or in conjunction with an antibiotic. Emergent BioSolutions has obtained National Institute of Allergy and Infectious Diseases (NIAID) grant funding to support non-clinical safety and efficacy studies and clinical trial planning.
