there's one feature of CRISPR that makes it arguably even better than our adaptive
immune system: CRISPR is heritable. When we are infected by a pathogen, our
adaptive immune system learns from the experience, making our next encounter
with that pathogen less of an ordeal. This is why vaccination is so effective: it involves
priming us with a weakened version of a pathogen to train our adaptive immune
system. Your children, though, won't benefit from the wealth of experience locked
away in your adaptive immune system. They have to experience an infection - or be
vaccinated - first hand before they can learn to deal with a given pathogen.
