Bible, your mom's immune system could very well kick this hep B illness. I like the doctor's statement:
"He told her that she had 90% chance of getting over it and being immuned to it. This was just a bad way to be vaccinated."
What he means is that if her immune system knocks out the hep B, she will then have the antibodies for it and cannot get it again, nor can she pass it on to someone else. I have this situation myself. She will, however, always test positive for hep B...as would someone who has had the immunization series.
ChronieMD, or Shelly or other nurses here, correct me if I'm wrong, please.
