Hep B....do some research on it. Hep B is only transmitted by unprotected sex, IV needle drug use, and bodily fluids. So, unless your newnbron is having sex, doing drugs or working in a Lab around other human body fluids like blood, then I don't see the need for it personally. It's prefectly suitable to delay that vacc until they are older and truly need it. They have to get a booster for it when they are older and more "at risk" anyway so why bombard a newborns body with the chemicals in the vacc to begin with? I'm HUGE on selective vaccines and spreading them out altogether, but I have done alot of research on the subject. I highly suggest you do the research yourself and make an informed descision that best suits you and your family. Everyone has their own personal reasons for making the descisions they make and no one has the right to pass judgement on others for their choices without knowing the full story. Dr Sear's website is pretty good about breaking down all vaccines, whats in them and possible side effects are. He is fairly "middle -of-the-road" and does not seem to sway one way or the other (pro-vaccine or anti-vaccine). But I really think you should dig deeper and read several sources in your education. Don't just listen to one person (i.e. your childs Pediatrician) and call it good. Regardless, YOU are in control of what they do to YOUR baby. You can request the Vit K shot only and pass on Hep B. I did with both my babies. But you still have to watch them or have a family member in the room with you watch them. My mom stopped them from giving my first child the Hep Shot even AFTER I made my wishes known, they just didn't bother to read the notes. Best wishes...
