It is reported ' The intersection of reporter and Zheng dexterous) Organization of unity, Center for Disease Prevention and Control of China, launch global of the largest scale first flow vaccine clinical trial reveal so far, vaccine safe and effective to every age group crowd flows in first of all kinds of in China, having inoculated a stitch, produced stronger immunity to reply, the rotating rate of male genital of antibody is up to 92.8% at most while inoculating for the 21st day. This research was also denied before 1957 the person who was born had certain immunity sayings to flow to first, explore, get first flow vaccine minimum effective dose 7.5, make for China and even the whole world first flow the intersection of vaccine and immune tactics offer the important basis. Britain's " lancet " magazine delivered the above-mentioned research report on December 16, and specially allot the long comment, think this value and importance of the random clinical trial are unquestionable. Israel <>It is a question, this research report has introduced China first and flowed the overall picture of the vaccine clinical trial completely, including the volunteer recruits, vaccine is researched and developed and produced, inoculate the tactics, test the exhaustive data with original procedure, vaccine security and immunity. This clinical trial is implemented in 10 cities and areas of Beijing, Jiangsu, Hebei, Henan, Hunan, Guangxi, the Inner Mongol. It is accepted that the volunteer that observes is a healthy crowd over 3, has covered between 3 years old and 87 -year-old 12691 people. The observation post uses vaccine to contain 10 all 8 types which vaccine enterprises produce by oneself of China vaccine. It adopt this clinical trial pair is blind, at random, last method at placebo, the vaccine security and immunity are original after observing first and flowing. The result reveals, 8 kinds of vaccine have very good security, there are not any speed hair irritated response, serious bad reaction or Green's syndrome in Bali,etc. to take place; Most bad reaction as slight passing, specializing in generating heat response symptom have 69 example in all while being getting serious, this proportion is similar to vaccine of seasonal influenza. The result still reveals, 8 kinds of vaccine have a better protection result. Among them, there is not vaccine to inoculate each and cleavage of 15 micrograms, the positive rate of age group antibody is 81%, 97%, 94% and 84% respectively over 3 years old - 11 years old, 12 years old - 17 years old, 18 years old - 59 years old, 60, have reached European Union's standard. The proportion of the person who has antibody is only 4% before vaccine that this clinical trial still finds, the high age group crowd of our country inoculates first and flows, not so many than low age group crowds. Judge, spread before this " whether person who born shed store to first in sure immunity before the 1957 " The saying can't be tenable. The clinical test result still reveals, before inoculating vaccine, the positive rate of antibody of inoculating group and control group crowd first and flowing is 4%; After inoculating vaccine, the positive rate of antibody of inoculating group and control group crowd first and flowing is 73% and 10% respectively, have fully proved first flows the antibody increases and comes from vaccine inoculation horizontally.
