In order to evaluate the safety and immunogenicity of its Influenza Vaccine (Split Virion), Inactivated, HulanBio authorized the Jiang Provincial Center for Disease Control and Prevention (CDC) as the main investigator from May 2006~Oct. 2006 to conduct a parallel blind control clinical study of the influenza vaccine in healthy populations older than 6 months of age. 
 

Serologic testing report issued by the National Institutes for the Control of Pharmaceutical and Biological Products (NICPBP) showed that: the influenza vaccine of HualanBio had a good immunogenicity performance. There was no significantly statistical difference on seroconversion ratios and protective rates after immunization between the experimental and control vaccines. The product quality complied with international criteria.

[Abstract] Objective To evaluate the safety and immunological effect of domestic split influenza virus vaccine. Methods 606 subjects were divided into three groups by under 6, 16—60 and above 60 years old. Each age group was divided as study group(n=213), control group I (n=195) and control group II(n=198) by Table of Random Number, one domestic vaccine and two imported vaccines were respectively inoculated in three group people. The differences of clinical side effect rate, antibody positive rate, protective rate and geometric mean titer (GMT) of these three vaccines were compared by using the statistical software with statistical significance of P<0.05. Results The side effect rate of study group, control group I and control group II was 3.76%(8/213), 4.10%(8/195), and 3.54%(7/198), respectively without statistical significance(χ2=0.87,P =0.93). The positive seroconversion rates of H1N1, H3N2 and B in these three groups were respectively 89.0％(190/213), 63.2％(135/213), 86.6％(184/213),88.9％(173/195), 61.7％(120/195), 87.2％(170/195),88.0％(174/198), 61.7％(122/198)and 84.7％(168/198). There were not statistical significance in the total positive seroconversion rate of each antibody type(χ2H1N1=0.94,P H1N1=0.63；χ2H3N2 =0.94,P H3N2=0.63；χ2B =0.75,PB =0.69). The average growth multiple of H1N1, H3N2 and B in these three groups were 10.7, 7.3, 8.4, 10.5, 6.3, 8.3, 10.2, 7.1, 8.8 times. There were no statistical significances in the GMT growth multiple of each antibody type (FH1N1=0.35,PH1N1=0.70；FN3N2=2.22,PN3N2=0.11；FB=1.51,PB=0.35). The antibody protective rates of H1N1, H3N2 and B were 100％(213/213),70.0％(149/213),95.3％(203/213),100％(195/195),66.7％(130/195),97.8％(191/195),99.5％(197/198),66.1％(131/198),96.7％(191/198)respectively. There was no statistical difference among the three vaccines(χ2H1N1=2.04,PH1N1=0.36；χ2H3N2 =0.74,PH3N2=0.69；χ2B =0.42,PB =0.82). Connclusion The domestic influenza split vaccine might be suitable for colony vaccination for its clinical safety and immunological effect.

Manufacturing scale 
    Huanlan Bio is a key national high-tech company in China engaging in the research, development, production, and commercialization of biological products, e.g.: blood product, vaccine, genetic engineering, etc. At present, Hualan has built the most advanced production line of influenza vaccine with the largest capacity in China. In 2010, Hualan had 10,920,000 doses of influenza vaccines passed the national lot release. Output of the seasonal influenza vaccine of Hualan was about 20 million doses in the recent three years, leading the industry in China. 
 

Quality assurance 
    HualanBio extended its quality management to chicken selection and chose HY-LINE VARIETY WHITE from the HY-LINE INTERNATIONAL in USA as the egg source after strict quarantine and screening, which is characterized by lower endotoxin content in eggs compared with other chickens. Hualan is the only vaccine manufacturer in China building high-standard chicken house itself and manufacturing influenza vaccine using eggs without immunization and antibiotics, which complies with quality specifications of the EU. Hualan obtains eggs with stable quality via carefully raising and strict management, thereby guarantee the quality of product from the very beginning. 
    Hulan purchased advanced machines from other countries, e.g.: the Automatic Virus Inoculation Machine, the Automatic Allantoic Fluid Harvesting Machine, the High Speed Filling and Packaging Equipment, etc., which makes it the first manufacturer in China meeting the international standard. Hualan selected imported prefilled syringes that are not only convenient for use but also cause slight injection pain. They can guarantee vaccines are stable and highly efficient and avoid iatrogenic contamination so as to ensure safety of users. The filling speed is 36,000 vials/hour, filling precision is high and aseptic control is much more scientific. All these make vaccine production without sub batches is possible. 
    Hualan has established transit logistics stations in Beijing, Suzhou, Chongqing and Guangzhou with modernized cold rooms of several thousand m2 installed and dozens of refrigerator cars equipped so as to provide service for the transportation of biological products. Those stations adopt the GPS Management System of Cold-chain Transportation developed by the GLP Software Management Company in USA to realize the monitoring of temperature and location of product at any time during the transportation.
