The acquisition of temperature-mutant (ts) defects in a strain of influenza virus has been shown in mice to be associated with diminished virulence, though the antibody-producing stimulus remained. It is suggested that three advantages may make ts strains potential sources of attenuated live influenza vaccine-the ease of obtaining the strains, the ease of testing the vaccine strain, and the high yield of vaccine doses from a single egg.
在小鼠身上已表明,一株流感病毒获得温度突变(ts)缺陷与毒力减弱有关,尽管产生抗体的刺激依然存在。有人提出,ts毒株可能成为减毒活流感疫苗潜在来源有三个优势——易于获得毒株、易于检测疫苗毒株以及从单个鸡蛋中可大量生产疫苗剂量。
