Vaccines and Medicine, You Know?

Vaccines were really never in my academic scope, and i never questioned them. So as a child, i took the vaccines according to the schedule. And when i was asked to take one  I took one my wife and i went to india a few years ago. I trained during an era where we were unprotected from hepotitus b. so if i would have gotten a needlestick from a patient who had active hepetitus be, i could have contracted it myself. That was my general understanding.
