I'm starting an ADN program. I've been accepted into the program for Spring 2015 and my requirements are due at the end of November. The first semester we have a clinical in a hospital that requires you to either be immune or be a 'non-converter' (going through a whole series twice and still showing no immunity) to hepb. The director of the nursing program said because of this I will have to forfeit my spot in the program if I cannot prove one or the other by the end of November when requirements are due. I never thought it would be possible for my HepB vaccine to come back negative, but apparently it is common. I wish I would have known sooner so I would have had time to do a whole series again. Oh well.. still praying for the booster to work!
