My family members don’t have Hep B and I am hoping to keep it this way. Per my hepatologist and my kids’ pediatrician, I had titers checked on my daughter at 1, 10, and 14 years old. Her HBs Ab went from 28.7 to 11.2 from 10 to 14 years old. Both kids received HBig and the vaccines from birth. One hepatologist recommends revaccinating if titer falls below 10 mIU/ml.
My pediatrician found this article on revaccination vs Hep B in late teenagers who received vaccinations during infancy in Human Vaccine immunotherapy which supports no booster needed for at least 30 years but there is uncertainty on duration of protection.
I was hoping to see if anyone has a more definitive answer. I tried to include a picture of part of the article. Also, how often should titers be rechecked in both those who received the vaccine as adults like my husband and those who received it at birth?
Thank you in advance for any responses.
