Sinovac Passes China's Ministry of Science and Technology 'Pandemic Influenza Vaccine R&D Project' Examination

BEIJING, CHINA--(CCNMatthews - Nov. 14, 2005) - Sinovac Biotech Ltd. (AMEX:SVA) announced that the Chinese Ministry of Science and Technology (MoST) has examined its Pandemic Influenza Vaccine R&D Project and accepted the results; clearing the way for continued sponsorship of the program.

China's MoST periodically evaluates the nationally funded Pandemic Influenza Vaccine R&D Project, and determines if sufficient progress has been made before Sinovac is permitted to continue. For the first critical step, top professionals from MoST conducted extensive evaluations of Sinovac's preclinical trials, and accepted all the results of this project to date.

Top professionals from MoST determined that Sinovac's method for developing an avian influenza vaccine for humans can be used for the prevention of influenza pandemic among humans, caused by the mutated strain from H5N1. Sinovac established in its preclinical trials that it has the ideal technological platform, personnel, equipment and management for the vaccine's development and production. Sinovac's preclinical trials have shown that its vaccine candidate has a high-quality safety and immunogenicity profile.

Sinovac developed its proprietary Pandemic Influenza Vaccine based on the NIBRG-14 virus strain provided by the British National Institute of Biological Standards and Control (NIBSC). Since April 2004, Sinovac completed its study of production processes; established a viral "seed bank" for vaccine production; and set up quality standards and testing methods.

Sinovac has applied for human clinical trials for its pandemic influenza vaccine with the Chinese State Food and Drug Administration (SFDA). In preparation for approval, Sinovac has already produced sufficient pandemic flu vaccines to complete human clinical trials.

Successful vaccine research and development of a Pandemic influenza vaccine is Sinovac's second national achievement against emerging virulent infectious diseases. In 2004 Sinovac developed a safe and effective inactivated SARS vaccine, and became the first company in the world to successfully complete phase I clinical trials.
