The Hepatitis B immunization is given in a series of three injections over a six month period.
Many diseases can be prevented by immunization, including polio, measles, mumps, rubella, chickenpox, hepatitis B, and influenza. By receiving vaccines, individuals can develop immunity to these diseases and reduce the risk of becoming infected.
To maintain immunity against Hepatitis B, it is recommended to get a series of three doses of the vaccine.
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.
