Behead breaks second liver " " how long to still need?

For the our country people that to getting second liver endangers, the antigen of surface of liver of whole crowd second that Ministry of Public Health announced a few days ago is carried rate drop considerably, it is a tremendous good news undoubtedly. Precaution of Chinese CDC(disease controls a center) when expert of immune program center was accepting our newspaper reporter to interview a few days ago, say, antigen of surface of liver of whole crowd second is carried rate drop, it is the effect that national immunity plans, be come ten years the country carries out a new student the achievement of strategy of second liver immunity. China passes the strategy that gives priority to with vaccine of vaccinal second liver to dominate the result that second liver place obtains, the height that got international society is admiring. Experts say, come ten years, antigen of surface of liver of second of our country grown crowd is carried rate is basic did not change, it is the affiliation of increasing healthy darling, make antigen of surface of liver of whole crowd second is carried rate fell. Epidemiology data of 　 of of count for much shows the person that the age when the person contracts second liver virus is carried chronically to whether developing, new student if period contracts second liver virus, 90% above can develop to be affected to carry; infant period chronically, 25%~30% development is become carry; chronically and grown period infection, development is 5%~10% only into the scale that carries chronically. The occurence rate of 5 years of liver cancer that the occurence rate of cirrhosis of 5 years of liver of patient of chronic second liver is patient of 12%~25%; liver cirrhosis is 6%~15% , 5 years occurence rate of liver function exhaustion is 20%~23% . Accordingly, come how many years Gao Xie of virus of liver of whole crowd second takes big like hill, weigh is on compatriots head. Liang Xiaofeng of director of center of program of Chinese CDC immunization tells a reporter, since 1992, our country brings into second liver vaccine children immunity to plan to manage, popularize vaccine of vaccinal hepatitis B, but the second liver vaccine of this moment is most and vaccinal grow up to seeming and be in school children, and vaccine and charge of its have an inoculation pay by unit and family, the have an inoculation of children of ministry of Chinese and Western leads inferior; to begin from 2002, second liver vaccine brings into children immunization program formally, the government pays vaccinal fee, among them ministry of Chinese and Western visits an area by alliance of international immunity vaccine (GAVI) offers second liver vaccine, to all new students free and vaccinal hepatitis B is vaccinal, the family pays vaccinal cost; only at the same time, begin from this period, the country pays attention to a new student very be born 24 hours a needle in is seasonable and vaccinal; begins from June 1, 2005, new student vaccine of vaccinal hepatitis B is all and free, make immunity of liver of second of our country children is enclothed thereby rate is constant increase, effect of second liver protection is more and more distinct. Study a proof, the protective effect that there is antibody respondent after vaccinal second liver is vaccinal can last 12 years commonly, average person does not need to undertake strengthening immunity. An investigation that has at and other places of Beijing, Shanghai, Heibei, Hunan, Guangdong, Guangxi shows, rate of the protection after immunity of vaccine of children second liver is vaccinal can be amounted to 93% . Heibei, Hunan, Shanghai, Guangxi is right 1986 ~1988 year be born the baby is followed visit 15 years of discovery, the antigen of second liver surface of children of group of vaccine of vaccinal second liver is carried rate is controlled in of 1.6% low-level, in vaccine of vaccinal second liver 15 years during antigen of second liver surface is carried rate did not see elevatory, although its protection antibody reachs antibody drop to spend a level to be lengthened along with time,drop somewhat, but rate of the protection when the 15th year still maintains in 90% the left and right sides. An observation at city of Hunan Province Xiangtan shows, after 57 children that to 9 years of ~11 the have an inoculation year ago lives vaccine of liver of 3 needles second undertake stitch second liver strengthens immune have an inoculation vaccinally, antibody drop spends a level to lift quickly, relatively rate of positive of antibody of protection of 6.5 times; increased to also come from 66.7% litres before strengthening immune have an inoculation before strengthening immune have an inoculation 100% . The children that these confirmed to have an inoculation passes second liver vaccine further has long-term immunity power to second liver virus. When the green 　 with Tu Mansheng abundant opportunity is in our domain ability center of program of Chinese CDC immunization, the reporter saw virus of liver of a second is popular global distributinging graph. Among them, antigen of surface of crowd second liver carries the area that leads Gt;8% to be enclothed by red, the area of Gt;2%lt;8% is enclothed by yellow, the area of Lt;2% is enclothed by green. Cui Fujiang of 2 rooms director weighs epidemic of center of program of Chinese CDC immunization, antigen of second liver surface carries general very difficult dispel, especially new student it is lifelong that period is affected and development is met almost to be carried chronically carry. Reduce antigen of surface of liver of second of our country crowd to always be carried rate, the only method that can rely on is " attenuant law " -- protect through strict immunity, let generation another acting new talent avoids virus of liver getting second to affect. Liang Xiaofeng says, at present antigen of surface of liver of second of 4 years old of crowds carries 1 year old of ～ of our country rate already dropped 0.96% , the person that have history of have an inoculation among them falls to 0.77% , and the person that do not have history of have an inoculation is carried rate still be as high as 5.57% ! Difference of district of our country vaccinate is big, in poor area of old little margin and hobo, still have the new life with not little amount to fail to get second liver immunity is protected. One of current key jobs remain the have an inoculation of second liver vaccine that has caught these fragile crowds to work, improve a new life especially seasonable have an inoculation leads a needle of second liver vaccine. Accordingly, the supportive sex measure that increases poor to old little margin area and hobo to collect the ground further, immunity of liver of our country second protects the effect to return meeting promotion. Cui Fujiang tells a reporter at the same time, come for years, antigen of surface of liver of 15 years old of age group second carries our country crowd rate is top all the time. In recent years our country is enhancing a new life while second liver immunity is protected, to the new student beyond key crowd especially old age children, also advancing have an inoculation of second liver immunity actively. Ministry of Public Health has issued batch of funds in last few years, divide area new life to the ministry the older age children beyond began second liver vaccine to check leakage reseed to work. On two weeks, ministry of Public Health arranged funds of 50 million yuan of projects again, use at liver of GAVI area second to control the job, the key that works among them, it is right since the project is carried out, be born the reseed checking leakage of children and promote be born to be in the home a needle of children is seasonable and vaccinal the job. This also is sure to accelerate the process that immunity of liver of second of our country crowd protects. According to Ministry of Public Health the bulletin a few days ago, our country was born 2005 whole journey have an inoculation leads vaccine of children second liver to already was amounted to 93% . Expert of center of program of Chinese CDC immunization with countrywide total population 1.3 billion, the whole nation year be born baby 16 million for base, combine level of have an inoculation of vaccine of liver of current children second, the have an inoculation of second liver vaccine that joins pair of old age children and tall danger crowd other prevent the synergism that controls measure element, undertook hopeful estimation: The antigen of second liver surface of Chinese crowd carries rate general to be in 10 years ～ drops after 15 years to 5% the left and right sides.
