It is state law that midwives/doctors/nurses "offer" the Hepatitis B Vaccine, Vitamin K injection, and erythromycin eye ointment at or around birth. Often nurses will say, "It's state law that baby's get HepB/VitK/eyegoop," but what is actually the case is that it is state law that they offer these to parents. Parents must "decline" if they do not want one or all three done to baby.
As for vaccines beyond the initial newborn period, it is parent's choice. Some pediatricians may "require" that baby receive vaccines for you to stay in their care, but baby is not legally required to have them. For school aged kids, getting a vaccine exemption in Clark County is fairly easy. If you plan on doing a delayed vaccine schedule or not vaxing altogether, then you will need to find a pediatrician that will at least tolerate, if not support this decision.
Awesome job, mama, for asking questions and educating yourself! You rock!
