Hep B shot at birth. Why?
I'm interested to know why babies are given the Hep B vaccination at birth. Can anyone please explain? I got mine as an adult and that was only because I was working with drug users at the time. I think it also came up with getting vaccinated before travel. I don't understand why there is a need to give this shot to a newborn. Also, I remember I needed 3 shots over about 18 months. I assume this is the same for babies?
btw - is the vaccine "live"?
note: I have no problem with vaccines per se, just don't understand this particular one.
TIA
