Abstract

Genetic recombination of influenza viruses provides the possibility of immediate reassortment and combination of genes and gene products in a single step. Thus, genetic variants with desirable attributes for vaccine production can be produced by deliberate genetic manipulation of viruses rather than by the empirical "hit or miss" methods of the past. Recombination of a high-yield laboratory strain (A0/PR/8) with a low-yield Hong Kong virus (Aichi strain) produced a high-yield recombinant virus (X-31) of Hong Kong antigenicity suitable for vaccine production. It is proposed that a prefabricated "library" of recombinants might anticipate the mutations which may arise in the future and also that live virus vaccines of greater stability may be produced by recombination of new and old viruses.

摘要

流感病毒的基因重组提供了在一步中立即进行基因和基因产物重配和组合的可能性。因此,可以通过对病毒进行有意的基因操作来产生具有疫苗生产所需特性的遗传变体,而不是采用过去那种经验性的“碰运气”方法。高产实验室毒株(A0/PR/8)与低产香港病毒(爱知毒株)的重组产生了具有香港抗原性的适合疫苗生产的高产重组病毒(X-31)。有人提出,预制的重组体“文库”可能会预测未来可能出现的突变,而且通过新老病毒的重组可能会生产出稳定性更高的活病毒疫苗。
