枫下家园 / 医药保健 / 看来有必要单独发个主贴:看图, 这个数据显示,随着疫苗注射时间流逝,虽然防止得病率的有效率下降,但是保护住院率和重症率依然非常有效,简单的来说就是保命。目前看保命还不用打booster shot, 两针就够

疫苗是用来防止被病毒感染的,你需要明白这个概念!如果疫苗的作用是减少病毒感染程度,那不是疫苗,那是一个药品,你需要明白第二个概念。

A vaccine is a type of medicine that trains the body’s immune system so that it can fight a disease it has not come into contact with before. Vaccines are designed to prevent disease, rather than treat a disease once you have caught it.

不一定把吧, 好比一个小孩子第一次面对bully 手足无措,而打疫苗相当于给孩子被Bully的培训知道怎么应对。药品相当于警察和老师家长直接介入制止bully
