I posted a while back (last year?) that my titers from my Hep B series from about 6-8yrs ago were negative. I went through the entire series again. Had a titer done last week...and it's NEGATIVE again! The nurse ended up giving me a shot to act as a "booster" and will test me later to see if they will need to try the series again.
I'm assuming I may be one of those people who don't get immunity, which sorta stinks.
