that are infected with Hepatitis B

已经感染乙肝病毒患者的血液
you find a lot of Hepatitis B surface subunits,

你会发现许多乙肝病毒的表面亚基
proteins without the nucleic acid circulating in their blood.

以及血液循环中存在没有核酸的蛋白质
What if I collect that blood from

如果我采集那些乙肝患者的血液
patients that are already infected with Hepatitis B,

抽提出乙肝病毒的蛋白质
purify the Hepatitis B protein, and inject that back into people?

并且将其回注入人体内将会如何呢
That would be a subunit vaccine

那将会产生疫苗
because I'm purifying a subunit of the virus

因为我提取的是病毒的亚基
that could be injected and hopefully induce an immune response.

可以被注射并且有可能引发免疫应答
It turns out that that works.

结果显示这方法是可行的
Any potential problems with that approach?

但是这种方法是否有潜在问题
Would you like to get that vaccine?

你会注射那种疫苗吗
