As previously announced, the Company began preclinical development in 2008. Sinovac is independently developing the EV 71 vaccine and will retain full commercialization rights of the vaccine upon approval. Created by Sydney University, the animal model showed cross protection and demonstrated that the vaccine is effective in animals. In addition, Sinovac is preparing to file a patent application covering the EV 71 vaccine.

Weidong Yin, Chairman, President & CEO, stated, "We are very pleased to submit the clinical trial application for the EV 71 vaccine to the SFDA. Our ability to submit the application ahead of the projected 2010 timeline is a validation of the R&D capabilities of the team developing this vaccine. A vaccine against EV 71 represents a significant unmet medical need, given that there are not effective preventive therapeutic alternatives for this life threatening viral illness affecting infants and children. Based on current expectations, we anticipate that the EV 71 vaccine, subject to positive human clinical trial results and commercialization, represents a significant flagship product opportunity for the Company as well as an opportunity to improve the lives of children around the world."
