中英对照：中国批准首例H5N1禽流感疫苗

　　人们广为担心，最终导致流感大流行的病毒将是一种变异的毒株，这将会使基于目前流行毒株所生产的库存疫苗完全失效。

　　There is widespread concern that the viral strain that could eventually cause a pandemic will be a mutated form, invalidating the stockpiles based on the current epidemic strain.

　　中国疾病控制中心的研究人员、北京科兴疫苗项目的首席科学家董小平告诉科学与发展网络（SciDev.Net）记者说，如果由于新的病毒毒株造成流感大流行，该疫苗会随着该新病毒株即时更新，而用不着重新设计和更换生产设备。国家食品药品管理局批准的该执照会允许这种疫苗不需要额外的临床试验就可以投入使用。

　　Dong Xiaoping, a researcher at China CDC and chief scientist of the Sinovac vaccine, told SciDev.Net that if pandemic flu were caused by a new strain, the vaccine would be immediately updated with the new strain, without the need to redesign and renovate production facilities.

　　The SFDA license would allow such a vaccine to be put into use without extra clinical trials.

　　董小平说：“在找出新的病毒毒株之前，这些库存的疫苗将会在有可能会出现流感大流行时提供最大可能的保护。”

　　"Before the new strain identification, the stockpiled vaccine will offer protection as much as possible amidst possible pandemic flu," Dong told SciDev.Net.

　　他补充说，对H5N1病毒发展的监控说明该病毒迄今为止还没有像预测的那样发生严重变异。

　　He added that monitoring of the development of H5N1 has shown that mutation of the virus has not so far been as extensive as predicted.
