Sinovac's Animal Rabies Vaccine RabEnd Receives Production License


BEIJING, Sept. 27, 2011 /PRNewswire-Asia/ -- Sinovac Biotech Ltd. (Nasdaq:SVA ), a leading provider of biopharmaceutical products in China, today announced that Tangshan Yian Biological Engineering Co., Ltd., its wholly owned subsidiary, received the production license for its developed inactivated animal rabies vaccine RabEnd from China's Ministry of Agriculture (MOA).


Tangshan Yian received the production license for its inactivated animal rabies vaccine on September 22, 2011 and previously obtained the New Animal Drug Certificate and the Certificate of Good Manufacturing Practices for Animal Drugs (GMP Certificate) from the Ministry of Agriculture. According to the Requirements of Chinese Good Manufacturing Practices for Animal Drugs, the production facility for animal vaccines at Tangshan Yian can be used to manufacture different inactivated animal vaccines with the similar production processes, which can yield cost savings and shorten launch schedules for subsequent products.


Dr. Weidong Yin, Chairman, President and CEO of Sinovac, remarked, "Receiving the production license for our animal rabies vaccines is a significant milestone as it represents the final step in the regulatory process before we launch this vaccine in China. Our inactivated vaccine, which is manufactured based on the local occurring rabies virus strain, provides pet owners in China with an inactivated animal rabies vaccine with improved effectiveness and competitive quality. Leveraging our ten years of human vaccine development, production and commercialization expertise, we are replicating our quality control systems and quality standards in animal vaccines. We have established a dedicated sales force and are teaming up with distributors to make this first China developed and manufactured inactivated animal rabies vaccine available to pet owners through the animal CDC's and veterinary hospitals."


About Animal Rabies

Rabies is a zoonotic disease (a disease that is transmitted to humans from animals) that is caused by a virus. The disease infects domestic and wild animals, and is spread to people through close contact with infected saliva via bites or scratches. Animal vaccination is the most effective strategy for reducing the incidence of rabies in humans by lowering human contact with rabid animals. On January 18, 2008, China's Ministry of Agriculture and Ministry of Health approved compulsory vaccination for dogs. Based on the estimation of the industry expert, there are about 80 million to 200 million dogs in China, which represents the potential of the market.


Rabies in China

China is one of the countries most threatened by rabies. Based on available data, approximately 2400 fatal human cases of rabies are reported each year China. Rabies is a vaccine-preventable disease and spending in China on human immunization has increased in recent years. According to the WHO, dogs cause 99% of human rabies deaths and the infection source can be controlled. The most cost effective strategy for preventing human rabies is to eliminate canine rabies through vaccination.
