I got the vaccine as an infant in the manner I was supposed to. I just got into a BSN program and it says that they need documentation of the series. It continues to say I need two of the shots by the day of my August orientation and the third and final by my Spring 2014 semester. I have heard many different answers to this question. Some say I have to have it again, others say that since I had it before I can't have it again...I am so confused...anyone know?
