I can tell you the reason we were given in nursing school is because of mother-infant transmission at birth. Also, a sad reality is that it protects babies in the event of abuse from having lifelong liver complications.
Well I can understand mother/infant but how would the baby get the vaccine if its pretty much infected from conception? Is it just something to help fight off the infection? Is vaccinating while already infected a thing? And the second part... so it's only in case of if the child could be abused that they would need it?
Ok, I'm more confused on that one. The other ones make sense as to why we need them, that one makes none.
