To be amplified, egg is perfect "the cultivation of influenza virus matrix". According to previous related official, researchers will bird cyst fluid qualified poisonous seeds inoculated into chicken embryo in 48-72 hours, after harvest, then kill the virus (inactivated) process, after this, then the chemical methods the virus broke, and then were purified, the separated viral antigen composition useful, finally for aseptic filtration, draw the vaccine stock solution,<a href="http://customcandymolds.com/rss/nike-sneakers-outlet-17.html">ナイキ スニーカー</a> http://customcandymolds.com/rss/nike-sneakers-outlet-17.html, diluted, final packing into vaccine. Not only is the H1N1 vaccine virus seed, in fact all flu vaccines are from WHO. "Every year, we have to decide what kind of vaccine virus flu vaccine, we must ensure that the vaccine virus to use is the most close when global epidemic of influenza virus type." Kearns said. Many people worry that usually lasts a long time for vaccine development, pre clinical and clinical trials of several steps is shortened, the security can not be guaranteed. "In fact, as you eat moon cakes this year, next year, red bean paste, fruit filling, is another stuffing. The virus is new, but the technology is old, new wine in old bottles." Huang Jianshi said. Kearns also said, the H1N1 virus is a kind of influenza virus, therefore the H1N1 vaccine is already mature production process based on the seasonal flu vaccine,<a href="http://www.buyroofhatch.com/images/_vti_log/gucci-bags-outlet-5007.html">グッチ バッグ</a> http://www.buyroofhatch.com/images/_vti_log/gucci-bags-outlet-5007.html, only for the virus. However, China's scientific research personnel are quickly developed, produced a flow of vaccine, there is also a very important reason, is a producer before send to strain early ready production preparation, in the approval process, the relevant departments have also taken vaccine expert centralized national top experts group unity of action with China characteristics, works with high efficiency. In addition, the quantitative vaccine is a very important link, vaccine experts China has not yet been sent to WHO when the quantitative standard, groping to find alternative standard substance and method of quantitative, early antigen. "Just as there is no weight, find a goods instead of weight as." Earlier, Zhao Kai said in an interview, the expert group on the four age groups, 13000 volunteers to test, test each needle which is 15 micrograms or 30 micrograms, is playing a needle or two needles. Subsequently, the expert group received standard and then to check, test error value is only 3%, all effectively and accurately, which means finding alternative methods for standard through, eventually, the expert group found that 15 micrograms a needle is effective. This number is significant, it means that the same limited time can produce more vaccine. Vaccine efficacy of 3 useful really? "Two months ago if you want to make vaccine, I may also hesitate, now if there are providing vaccine, I will go." The science writer, immunology researchers thin camel said, "now it seems few adverse drug reactions, should be safe." Chinese Center for Disease Control and prevention stressed that the effectiveness of the vaccine in people over the age of 3 in general generate immune protection effect in more than 85%. "You can be understood as 100 individuals can protect the 85 person, also can be understood as 100 people 15 people playing like didn't play." Huang Jianshi said. "A lot of people vaccinated, think oneself but it got a stream, which is a reason." Kearns lobbyists
