When you are training to become a medical professional, such as a nurse or doctor, they teach you about evidence-based practice, in other words, what you do in medicine is based on research. I think this is why the nurse comes off as judgmental. In the nurse's mind, this is what he/she knows to be the best practice and perhaps thinks the mom is ignorant. It appears that sometimes when the "good" outweighs the "bad," medical professionals neglect mentioning the bad. I see this a lot in the hospital when medications are given, only the common adverse effects are told to the patient. But what if you happen to be that .1% who get agranulocytosis from a particular medication? Wouldn't you feel like you were duped? I would encourage all patients to ask questions and don't settle for anything but an answer. I also think its dangerous to go the other way and think because this happens to some people it will happen to everyone and therefore we should get rid of it. I will probably allow my kids to be vaccinated in the future, however, if it's not neccessary at that moment (such as HEP B Vaccine right when the child is born) I may wait until my child is older and has an immune system that can tolerate the stress.
