I am not sure where did you get the 100% thing but for the record I am not claiming that. What I am noticing is that it used to be an objective criterion for the inoculation, seemingly based on the concept of immunity.

I got the "100% thing" when I said it in the first post, and you started responding "if vaccines don't give immunity", yada yada. In response to me saying tehy don't give 100% immunity.

You responded to my assertion that vaccines used to give immunity with "no" so I thought you are arguing that, sorry for misunderstanding.
