If vaccines never gave immunity how come people who had the natural immunity from having the disease naturally were not required to be vaccinated? Actually even in my older years all I had to present as a proof of vaccination to the US government was my blood with antibodies.
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.
