BEIJING, April 24, 2014

BEIJING, April 24, 2014 /PRNewswire/ -- Sinovac Biotech Ltd. (NASDAQ: SVA), a
leading China-based vaccine manufacturer, announced today that it has received
notification that a RMB 60 million free government grant has been approved by
China's Ministry of Finance, National Development and Reform Commission,
Ministry of Industry and Information Technology, and National Health and
Family Planning Commission for construction of the Company's dedicated
production facility for its Enterovirus 71 (EV71) vaccine against hand foot
and mouth disease (HFMD). Given the severity of HFMD epidemic levels in China
and the government's focus on developing the biotechnology industry, Sinovac's
EV71 vaccine commercial production project was approved as one of the projects
supported by the Dedicated Funds for Strategic New Emerging Industry
Development. The funding criteria as outlined in this grant are to complete
the construction of its production facility in compliance with China's new GMP
guidelines with an annual capacity of 20 million doses of EV71 vaccine and to
commercialize the vaccine in China. The grant will be funded in several
tranches, of which RMB 20 million will be provided within the year, and the
remaining will be provided after the criteria are met.

Mr. Weidong Yin, Chairman, President and CEO of Sinovac, commented, "From 2007
to 2013, over 9 million cases of HFMD have reported in China with
approximately 2,700 reported fatalities. This epidemic situation represents a
significant unmet medical need for the EV71 vaccine. With the government
support for building out the dedicated production capacity, Sinovac is poised
to provide the EV71 vaccine to help address this potentially fatal childhood
disease for which no commercialized vaccine and no EV71 specific treatment
exist. The grant provides the confidence and encouragement that EV71 vaccine
is urgently needed and has attracted the attention from the Chinese
government. We look forward to working with the regulatory agencies to
complete the vaccine registration process as soon as possible."

In March 2013, Sinovac completed the Phase III clinical trial for its EV71
vaccine candidate and reported preliminary top-line data that showed
approximately 95% efficacy rate for the vaccine against HFMD caused by
enterovirus 71 (EV71). Throughout the three phases of the clinical trials, the
results demonstrated a good safety, immunogenicity and efficacy profile for
Sinovac's proprietary EV71 vaccine candidate. In May 2013, Sinovac's new drug
application (NDA) for its proprietary EV71 vaccine has been filed and accepted
by the China Food and Drug Administration ("CFDA"). Currently, the NDA is
under the technological review by Centers for Drug Evaluation.
