This is an important distinction because the efficacy of a live priming vaccine could be affected by existing immunity to the microorganism and to related species.
区分这个很重要，因为初次免疫的功效会受到已经存在的针对该细菌或者相关细菌的免疫性的影响。
The method taught herein functions to offset pre-existing immunity through the delivery of the protein or antigen by a cocktail of at least two adenoviral serotypes.
本文所述方法的作用是通过至少两种腺病毒血清型混合物送递蛋白质或抗原，以抵消已有的免疫力。
Whether this reflects the persistence of pre-existing immunity at the time of revaccination or lower rates of revaccination in the study populations cannot be determined.
这是因为再次接种时前次的免疫性仍然存在，抑或是因为在研究人群中再次接种率较低，对此目前尚无定论。
When people have no pre-existing immunity to a flu virus, they need not just one but two doses of vaccine several weeks apart - making it very hard to immunise many people in time to protect them.
当人们对流感病毒没有预先免疫性，他们就需要几周间隔的两次注射而不是一次注射-这在当时免疫接种很多人去保护他们操作是非常困难的。
