According to January 11 (Beijing time) of Britain " Daily Telegraph " Report, American researcher antibody that produce carry on research in the body to infect with first type the intersection of H1N1 and patient of influenza virus 2009, find some antibodies among them can oppose many kinds of influenza virus. Issue this research results on magazine of " medical science of the experiment " published newly, from develop common the intersection of influenza and the intersection of vaccine and nearly one, scientist can can develop a injection immune vaccine all the life in view of the above perhaps. Will sweep across global first type H1N1 influenza virus and let 14,000 people die in 2009. Research group composed of medical college of American Emory university and Chicago University scientist, lying between the patient at the age of 21 to 45 to 9 ages carries on research. These patients have been all infected with first type H1N1 influenza virus in 2009, its severity is different, symptom disappears several days after some patients; But some patients are very serious, accept 2 months -longly that is hospitalized for treatment. Researchers find, these patients have produced the antibody that can oppose influenza virus in the body, influenza virus one of various seasonal H1N1 that 5 antibodies that researchers separated out can confront with each other and present in the past ten years, appearing in 1918 " Spain's influenza " Virus one, fatal H5N1 bird flu virus one. Researchers of Chicago University Patrick and Willson say, perhaps the scientist can search for by following the clues in view of the above, developed common vaccine that can oppose all influenza bacterial strain immune vaccine all the life, even can develop a injection. Emory's microbiolody and fertile tile of amynologic assistant professor Zhan Sri Lankan of the university do not specially express, the data reveal the influenza bacterial strain which is infected with 2009 may induce the body to produce the antibody with protective action, can't almost see the production of this kind of antibody after is infected with seasonal influenza or injects vaccine of influenza ing, this shows, if the human immune system is stimulated by the correct one, will produce this kind of antibody in the human body, the scientist can develop vaccine of common influenza in view of the above. Vaccine of effective common influenza means great to controlling influenza. At present, a lot of scientific research groups are developing vaccine of common influenza, by making people not suffer from influenza or immune all one's life in decades. Harmful member or pathogen that the antibody is made, can attack the outside bacterium by some leukocytes and the virus carried. Researchers extract the leukocyte that patients made the antibody from patient's body, and isolate the antibody gene from leukocyte and use these genes to produce 86 kinds of antibodies subsequently, and tested which kind of bacterial strain of influenza these antibodies can confront with each other. The intersection of research and group this plan, check those, infect influenza virus next immunoreaction without sick person. Have one injection omnipotent vaccine, no longer catch a cold all the life. This sound very much like advertising lines, scientist straight painstakingly these decades, attempt to develop the so-called common influenza vaccine inhibiting all type influenza. And is developed successfully, annual protective inoculation will become history. Though this kind of idea has already proved feasible on mouse, ferret and monkey, and start the human clinical trial, but because a large number of difficult problems have not been solved in the theory and practice, we mustn't expect it to prevent the virus from infecting completely, perhaps the best result just lightens condition and restriction and spreads greatly. The researchers who publish this thesis will probably think in this way too. (Reporter Liu Xia
