      1. Diabetes patients are twice as likely to contract Hepatitis B and more prone to liver disease and to develop chronic hepatitis
      2. Consider for older age 60 years with additional risks (but lower efficacy in this group)
      3. (2012) Presc Lett 19(2): 8-9
  2. Contraindications
    1. Anaphylactic reaction to baker's yeast
  3. Efficacy
    1. Starting series after age 3 months may improve immunity
    2. Immunity appears to be lifelong after series
    3. Perinatal and childhood exposure once accounted for one quarter of Chronic Hepatitis B
      1. Since 2004, >92% of U.S. children have complete Hepatitis B immunity

  6. Alternative Protocols
    1. Rapid Vaccination (3 weeks) French Study
      1. French Protocol
        1. Regular: Days 0, 28, and 56
        2. Rapid: Days 0, 10, and 21
      2. Efficacy compared with regular French schedule
        1. Day 28: Higher seroprotection than reg schedule
        2. Day 56: Lower seroprotection than regular
        3. Day 365: Same seroprotection as regular schedule

      2. Efficacy
        1. Month 3: Greater seroprotective effect

          1. Higher Antibody titer for standard group
          2. Suggests possible longer term protection

Hepatitis B Vaccine (C0062527)

Definition (HL7V3.0) <p>hepatitis B vaccine, NOS</p>
Definition (NCI) A non-infectious mixture containing recombinant hepatitis B surface antigen (HBsAg) in a liquid vehicle. Immunization with the hepatitis B vaccine induces the formation of specific anti-hepatitis B antibodies and an active immunity against hepatitis B infection.
