悉尼消息:澳大利亚科学家宣布,对流感病毒重大秘密(已知的疫苗对其无能为力)的研究取得了进展。墨尔本和堪培拉的科学家测定了流感病毒表面的一种蛋白质的三维结构,此结构常很快改变,以挫败药物战胜新流感毒株的扩散。流感病毒能改变其分子形状,意味着在研制出对特异毒株的疫苗之前,此病毒已经改变了它的分子形状。澳大利亚的研究证实了上述情况是如何发 SYDNEY (Reuters) - Australian scientists have announced the progress made in the study of the major secret of the flu virus that the known vaccine does not help. Scientists in Melbourne and Canberra have measured the three-dimensional structure of a protein on the surface of the flu virus, a structure that often changes quickly to frustrate the spread of drugs against new flu strains. Influenza virus can change its molecular shape, meaning that the virus has changed its molecular shape before it can be made into a vaccine against a specific strain. Australian research confirms how this happened
