Most kids handle vaccines fine, but some have severe reactions like myocarditis or rashes. If we could identify which children are biologically susceptible to specific shots, we could exempt them instead of giving every child every vaccine.
Most kids get shots in general are fine, and you wouldn't see anything. But some kids, they have a bad reaction, they get terrible rashes, they get all sorts of things in the short term, myocarditis, like, what is it? Maybe if we figured out what is the susceptibility in the heart for myocarditis, we could say you shouldn't get that shot. Or maybe there's a certain subset of the population that has a brain chemistry or a brain setup or a brain blood barrier that doesn't do well with the DTaP vaccine. And so let's figure that out first. And then maybe those are the kids that just don't get that vaccine. Doesn't mean that we should just take away the measles vaccine or the polio. Polio vaccine. But maybe we could figure out what kids are going to have the reaction so we don't give to them or figure out what's in there that's causing the reaction.
