Is Hep B Vaccine Necessary Even With Positive Antibodies?

My latest anti-HBs count was 214.33 u/L and there was a reference note there: positive COI 10.0. What does that mean? If I have positive antibodies, do I still have to get another booster of Hep B vaccine considering that I am a nurse working in a hemodialysis unit? And if I did really develop natural antibodies, won't I anymore contract the disease in cases of needle stick injury or accidental contact of infected fluids?

Hi there.
Thanks for using HCM.
Anti HBs of 213.33 u/L means you have protective levels of antibbodies. Anything more than 10 is protective and you do not need any more booster.
Now that you have protective level of antibodies you will not contract the disease in cases of needle stick injury or accidental contact of infected fluids.
