Mr. Weidong Yin, Chairman, President and CEO of Sinovac, commented, "We are pleased to receive approval to market Panflu in Hong Kong, as it represents an opportunity to significantly expand our market reach. In working closely with Hong Kong officials on regulatory approval for Panflu, we have gained knowledge about the regulatory process there and plan to submit applications in the near future for additional vaccines, specifically Panflu.1 for swine flu and Anflu. And at the same time, Hong Kong officials have gained an overall understanding of the quality of Sinovac's product. The approval in Hong Kong for Panflu is a significant step in our mission to distribute our affordable, high-quality and safe vaccines on a global basis."
