The Hepatitis B immunization is given in a series of three injections over a six month period.
hepatitis b is a disease that's preventable by vaccination
A level of 10.0 mIU/mL or greater after three doses of the Hep B vaccine demonstrates immunity.
The series should not be restarted; resume the series where it was interrupted.
The causative agent for Hepatitis B is Hepatitis B virus.
Artificial active immunity. Artificial because it is due to vaccination. Active because the body is stimulated by the vaccine to produce antibodies against Hepatitis B virus antigen.
Current recommendations for immunization for hepatitis B demonstrate belief that overdose is not a concern. For example, for the high-risk patient who has a three-injection series and does not demonstrate immunity via positive titer, a one-time repeat of the series if three is recommended. Similarly, for the patient unsure of Hep B immunization status who has a high-risk needle-stick, immunization is recommended.
The Twinrix vaccine is typically given in 3 doses. This is normal.
You do not have Hepatitis Surface B antigens present. This can mean you do not have Hep B or if you have had vaccinations and are getting tested within months of the shots, they have not produced sufficient immunity. (If the titer is done years after the immunization, the levels may be non-reactive, but the body still may produce an anamnestic response demonstrating that low titer levels years after immunization are not an effective indicator of immune status.)
