In absence of vaccines, how many serious diseases a human body was supposed to have seen throughout its life? Probably one or two, then you’d mostly be dead.
I don’t understand where this assumption is coming from (both in terms of “one or two” specifically, and that there should be any particular number in the first place).
With our usual vaccination schedule, we now routinely prime our immune system against twelve diseases
Is the idea here that all vaccines have the same fixed risk level, regardless of what it’s vaccinating against, whereas non-serious disases have a lower risk level? And most of the twelve diseases are not in the “serious” category?
