回复 59楼 gigivivi 的帖子
CDC Web Archives 选择2015年前任何一个时间点
老的定义:
Vaccination: Injection of a killed or weakened infectious organism in order to prevent the disease.
Vaccine: A product that produces immunity therefore protecting the body from the disease. Vaccines are administered through needle injections, by mouth and by aerosol.
看了这个网页,对Vaccination的定义早就落后了,当然需要改进
Vaccination: Injection of a killed or weakened infectious organism in order to prevent the disease.
首先“killed or weakened infectious organism" 早就落后时代,且不说mRNA疫苗,还有DNA疫苗,重组蛋白质疫苗。其次,现在的vaccine定义不只是prevent,也有用于治疗(treatment)的。
随着时代变迁,CDC改变网页上的定义来反映当下最新的科学进展,在我看来当然可以。你贴的时间线那张图来自X。就这样。
