I Vaccine Market in China
Vaccine Manufacturer
• Manufacturers
• There are 35 local manufacturers which produce more than 40
kinds of vaccines against 26 kinds of diseases ,the biggest
manufacturer is China National Biological Group (CNBG),it is a
central government owned company which produce almost all
kinds of vaccines licensed in China.
• Additionally, 5 multinational companies are also existing in Chinese
market which mainly sell the imported vaccine ,recently , three of
them(Sanofi ,GSK and Novatis) have become local companies
through direct invest /acquisition or Joint venture
Market Size
• The total market for human vaccine in China is around 2.7 billion USD
in 2011 , the category I * vaccine are around 0.9 billion while the
category II** vaccine are 1.8 billion USD.
2011 Vaccine Market Share By Lot Release Volume in China
Total = 0.9 Bn doses
* Category I vaccines cover all vaccines within the EPI, free and compulsary immunization ;
**Category II vaccines cover non-EPI vaccines, need to pay and not compulsary immunization.
Competitive Landscape I
Note: X% represents the share of lot release of respective products
in 2011 for Category I Vaccines

II Strategy of CDBIO to enter into
vaccine market
Introduction
CDBIO
• CDBIO was established in 2002 , Jointly invested by Liaoning
Cheng Da Co., Ltd and Liaoning Bio-Medical Equipment
Institute, it is a research-driven company which mainly
focuses on manufacturing and marketing of biological and
pharmaceutical products.
• There are over 600 employees in CDBIO, 50% of them
holding bachelor degree,54 of them holding master and
doctor degree. The staff who participates in production and
quality management are well trained of current GMP

CDBIO Introduction
Project selection
• In China , the category I vaccine market is almost shared by CNBG
and Tiantan Bio*, and for this category, it is purchased by central
government through tenders;
• For category II vaccine , it is directly purchase by CDC or hospital
according to the actual need of patients , the other manufacturers,
including the multinational companies, are mainly competing on this
market .
• Under the circumstance , Why rabies vaccine was selected by CDBIO
as the first project?
*TianTan Bio is a public company ,which also belong to CNBG.
• In 2002(when CDBIO established) ,there are around 15 local
manufacturers and 2 Multinational companies enrolled in rabies
vaccine market , and the market size for the vaccine is around 50-60
million doses /year ,it was very competitive but huge market.
• After market analysis ,the management of CDBIO thought there
were still good chance to enter into this market as our partner has
more advanced technology than the other competitors .
• The technology is developed in1984 by world Health Organization
and the Rockefeller Foundation ,it is finally succeeded in 1999.This
technology is based on the perfusion Vero cell culture on high
density microcarriers in bioreactors
Technology form in China
•
In 2002 ,the major technology for rabies vaccine manufacturing in China

Technology transfer
Program to be Established
In June 2002, CDBIO signed a contract with BARI consulting Corp. to produce
rabies vaccine by using high density microcarriers in bioreactor.
Cooperate Research
In June the same year, a R&D team was organized. The PV-2061, fixed rabies
virus and Vero cell were respectively obtained from CDC of USA and ATCC.
The specialists under the lead of Dr. Aycardi began to teach the related
technology to us. Meanwhile, the constructing of factory was in plan.
Sample testing by NCL
In June 2003, after succeeding on a pilot scale, we officially applied to SFDA for
the approval. The clinical trials has been carried out.
Training for Production
In the early 2004, the new coming staff were well trained. At the same time, the
manufacture of commercial batches has been started .
Product on Market
In May ,2005 , the product was approved by SFDA and launched in the market.
Bioreactor for perfusion cell culture
Perfusion cell culture
technology can
1. Provide enough
medium nutrition for
the Vero cell growth
to reduce the cell
broken ;
2.Keepcontinuously
virus harvest to
insure the batch
consistency;
3. Provide closed
pipeline during the
whole production
process to avoid
contamination
instead of adding
antibiotics.
Column Chromatography System
Four series column
chromatography
system can
remove more than
99.9% impurities
such as residual
Vero cell DNA ,
Bovine serum etc.
CDBIO is the first
company to use
the four column
chromatography
system for the
commercial
manufacturing in
China .

Japanese encephalitis vaccine
• China is Japanese encephalitis(JE) epidemic country , and the major
vaccine used for the JE prevention is live attenuated vaccine which
produced base on PHK cells . The vaccine has good immunogenicity
but has the potential risk to use on epidemic season or
immunodeficiency people .
• With the same technology platform , CDBIO started the development of
new generation of inactivated JE vaccine produced on Vero cell to
replace the live vaccine ,in 2008 , the “Green” Inactivated JE vaccine
was approved by SFDA . The new JE vaccine is only formulated with
human serum albumin and dextran 40 as stabilizer , free of thiomersal ,
adjuvant and antibiotics .

• III Government support for vaccine
manufacturers
Lands
• Usually , the local government will supply the
industrial land to vaccine manufacturer at low cost
, and the land will be only used for the R&D and
manufacture of vaccines .
• The price of the land depend on the different
policy of each provinces /cities .
Financial
• 1 Scientific research
• For each research of new product , there will be one time research
fund from central and local government.
• 2. Interest
• The local government will provide some loans free of interest , but
it depend on companies operation situation /project construction .
• Tax
• The tax rate for vaccine manufacture is lower than the normal rate .
IV Sales and marketing
SPEEDA - chromatographically
purified Vero cell rabies vaccine
• The first product –SPEEDA was launched in May ,2005
,it is the first rabies vaccine which get the Lot release
certificate from National institute for Control of
Pharmaceutical and Biological Products (NICPBP)
,China .
• Till 2011 , SPEEDA was sold in 20 countries with the
quantity more than 100 million doses , and there is no
immunization failure case reported after finishing the full
schedule, its immunogenicity and safety are well
accepted by the doctors .

Clinical data
• After launch of SPEEDA since 2005 , CDBIO has conducted a
series of clinical trials/PMS to observe the safety and
immunogenicity of the product at different institutes /hospitals /
CDCs , the trials including :
• 1. Pre-exposure vaccination (IM route on day 0,7 and 28)
• 2. Post-exposure treatment (Essen regimen by IM route),
• 3. Post-exposure treatment( 2-1-1 regimen by IM route) ,
• 4. Simulated Post –exposure treatment ( Modified TRCS
regimen by ID route)

4. Intradermal Clinical Study of SPEEDA in
Thailand by Thai Red Cross Society ,QSMI
Seventy healthy volunteers were enrolled into the study. All volunteer subjects
were randomly allocated into two groups to receive rabies vaccinations with
modified TRC-ID regimen with two distinct kinds of vaccines.
Subjects in group I (n=35) received chromatographically purified Vero cell rabies
vaccine (Speeda®), Lot no. 200904012-3 of potency 6.4 IU/dose.
Subjects in group II (n=35) received purified Vero cell rabies vaccine (Verorab®),
Lot no.D0998 of potency 10.6 IU/dose.
Blood samples were taken before vaccination on day 0 then day 7, 14, 28, 90,
180 and 360 afterward for serological analysis of rabies neutralizing antibody
titers (RNab titers) by the rapid fluorescent focus inhibition test (RFFIT).

JEVAC-Inactivated Japanese
Encephalitis vaccine (Vero cell)
• The second product –JEVAC , Inactivated Japanese
Encephalitis vaccine was launched in 2009 , and it quickly
become the first choice for JE prevent in category II market
,more than 4 millions doses were sold in China.
• As JEVAC is free of antibiotics ,adjuvant and especially
thiomersal ,which highly preferred for the children vaccination
. According to the clinical report and post marketing
surveillance data , the result can reach a satisfied level on
both efficacy and safety after vaccination.
Clinical report
