Overview

Hepatitis B vaccine (recombinant; Engerix-B(R), Recombivax HB(R)) and hepatitis B vaccine (recombinant) adjuvanted (Heplisav-B(R)) are inactivated recombinant vaccines containing hepatitis B surface antigen (HBsAg); they are used to stimulate active immunity to hepatitis B virus (HBV) infection.

Hepatitis B vaccine (recombinant) stimulates active immunity to HBV infection. Hepatitis B virus (HBV) is a DNA virus with a long incubation period. Hepatitis B virus (HBV) is a DNA virus with a long incubation period.

Hepatitis B surface antigen (HBsAg), which is present in hepatitis B vaccine, promotes the production of antibody to HBsAg (anti-HBs); anti-HBs neutralizes HBV so that its infective or pathogenic properties are inhibited. Antibody concentrations >=10 mIU/mL against HBsAg are recognized as conferring protection against HBV infection.

Hepatitis B vaccine is commercially available in the U.S. as three monovalent vaccines: hepatitis B vaccine (recombinant; Engerix-B(R) and Recombivax HB(R)) and hepatitis B vaccine (recombinant), adjuvanted (Heplisav-B(R)). Hepatitis B vaccine also is commercially available in a fixed-combination vaccine with hepatitis A virus vaccine (HepA-HepB; Twinrix(R)), in a fixed-combination vaccine that contains diphtheria, tetanus, pertussis, hepatitis B, and poliovirus antigens (DTaP-HepB-IPV; Pediarix(R)), and in a fixed-combination vaccine that contains diphtheria, tetanus, pertussis, hepatitis B, poliovirus, and Haemophilus influenza type b (Hib) antigens (DTaP-IPV-Hib-HepB; Vaxelis(R)).

Both Recombivax HB(R) and Engerix-B(R) contain HBsAg prepared using yeast cells (Saccharomyces cerevisiae) and recombinant DNA technology. These vaccines are available in several formulations containing different concentrations of HBsAg. Recombivax HB(R) is supplied in 3 formulations.

Each 1-mL dose of Recombivax HB(R) Adult Formulation contains 10 mcg of HBsAg; each 0.5-mL dose of Recombivax HB(R) Pediatric/Adolescent Formulation contains 5 mcg of HBsAg; and each 1-mL dose of Recombivax HB(R) Dialysis Formulation contains 40 mcg of HBsAg. In each formulation, the antigen is adsorbed onto approximately 0.5 mg of aluminum (as amorphous aluminum hydroxyphosphate sulfate) per mL of vaccine. Engerix-B(R) is supplied as syringes or vials for adults, and syringes for children and adolescents.

Each 1-mL dose of Engerix-B(R) Adult contains 20 mcg of HBsAg adsorbed onto 0.5 mg of aluminum (as aluminum hydroxide) and each 0.5-mL dose of Engerix-B(R) Pediatric/Adolescent contains 10 mcg of HBsAg adsorbed onto 0.25 mg of aluminum (as aluminum hydroxide).

Heplisav-B(R) contains HBsAg expressed in a recombinant strain of Hansenula polymorpha yeast. Heplisav-B(R) is prepared by combining the purified HBsAg together with the CpG 1018 adjuvant. Heplisav-B(R) is supplied as prefilled syringes; each 0.5-mL dose is formulated to contain 20 mcg of HBsAg and 3000 mcg of CpG 1018 adjuvant.

Each dose may contain residual amounts of yeast protein (<=5% of total protein), yeast DNA (<20 picogram), and deoxycholate (<0.9 ppm) from the HBsAg manufacturing process.

DTaP-HepB-IPV (Pediarix(R)) is a fixed-combination vaccine containing diphtheria, tetanus, pertussis, hepatitis B, and poliovirus antigens. The hepatitis B antigen contained in Pediarix(R) is identical to that contained in Engerix-B(R) monovalent hepatitis B vaccine. The diphtheria, tetanus, and pertussis antigens are identical to those contained in Infanrix(R) (DTaP) vaccine.

The poliovirus antigens contained in Pediarix(R) are similar to those contained in the commercially available monovalent inactivated poliovirus vaccine (IPV) vaccine. Each 0.5-mL dose of Pediarix(R) is formulated to contain 25 Lf of diphtheria toxoid, 10 Lf of tetanus toxoid, 58 mcg of pertussis antigens, 10 mcg of HBsAg, 40 D-antigen units (DU) of Type 1 poliovirus, 8 DU of Type 2 poliovirus, and 32 DU of Type 3 poliovirus. Each 0.5 mL of Pediarix(R) contains 4.5 mg of sodium chloride, not more than 0.85 mg of aluminum adjuvant, not more than 100 mcg of polysorbate 80, and not more than 100 mcg of residual formaldehyde.

Although neomycin sulfate and polymyxin B are used in the manufacturing process of the poliovirus antigen component, Pediarix(R) contains no more than 0.05 and 0.01 ng, respectively, of these anti-infectives per dose. No more than 5% yeast protein may be present in Pediarix(R) as part of the hepatitis B antigen component.

HepA-HepB (Twinrix(R)) is a fixed-combination vaccine that contains both hepatitis A and hepatitis B antigens. Twinrix(R) is a sterile suspension containing the antigenic components used to produce Havrix(R) monovalent hepatitis A virus vaccine inactivated and Engerix-B(R) monovalent hepatitis B vaccine. Each antigenic component is adsorbed separately onto aluminum phosphate or aluminum hydroxide and then pooled to form the fixed-combination vaccine.

Each 1-mL dose of Twinrix(R) contains 720 units of hepatitis A viral antigen and 20 mcg of HBsAg and also contains 0.45 mg of aluminum (as aluminum hydroxide and aluminum phosphate). Each 1-mL dose of the vaccine also contains residual MRC-5 cellular (not exceeding 2.5 mcg), yeast proteins (not exceeding 5%), trace amounts of formaldehyde (not exceeding 0.1 mg), trace amounts of neomycin sulfate (not exceeding 0.02 mcg), and amino acids in a phosphate-buffered saline solution with polysorbate (Tween(R)) 20.

DTaP-IPV-Hib-HepB (Vaxelis(R)) is a fixed-combination vaccine that contains diphtheria, tetanus, pertussis, hepatitis B, poliovirus, and Hib antigens. Vaxelis(R) contains HBsAg prepared using yeast cells (Saccharomyces cerevisiae containing the gene for the adw subtype of HBsAg) and recombinant DNA technology. Each 0.5 mL dose of Vaxelis(R) contains 15 Lf diphtheria toxoid, 5 Lf tetanus toxoid, acellular pertussis antigens (20 mcg detoxified pertussis toxin, 20 mcg filamentous hemagglutinin, 3 mcg pertactin, 5 mcg fimbriae types 2 and 3), inactivated polioviruses (29 DU Type 1, 7 DU Type 2, 26 DU Type 3), 3 mcg polyribosylribitol phosphate of H. influenzae type b covalently bound to 50 mcg of the outer membrane protein complex of Neisseria meningitidis serogroup B, and 10 mcg HBsAg.

Each 0.5 mL dose contains 319 mcg aluminum from aluminum salts used as adjuvants.

The hepatitis B vaccine is highly immunogenic in immunocompetent neonates, children, adolescents, and adults. More than 90% of infants, children, adolescents, and healthy adults under 40 years of age develop protective antibody levels following completion of the hepatitis B vaccine series. However, immunogenicity decreases with advancing age, with only 75% of individuals 60 years of age achieving seroprotection after completion of the vaccine series.

Among adults receiving Heplisav-B(R), 90-100% develop adequate antibody titers after the 2-dose regimen.

The hepatitis B vaccine is 80-100% effective in preventing infection or clinical hepatitis when the full series is administered. Higher vaccine doses or additional doses are often required to achieve seroprotection in dialysis patients and other immunocompromised populations. Although antibody concentrations wane over time, immune memory persists for more than 30 years, providing continued protection against clinically significant HBV infection; therefore, booster doses are not recommended for immunocompetent individuals.

USES: This vaccine is used to help prevent hepatitis B. Hepatitis B infection can cause serious problems including liver failure, long-term hepatitis B infection, cirrhosis, and liver cancer. Vaccination is the best way to protect against this infection.

This vaccine works by increasing the body's natural defense (immunity) against the virus. The vaccine is recommended for people of all ages, especially those at an increased risk of getting the infection. Those at an increased risk include health care personnel, lab workers who handle blood and patient specimens, police, fire and emergency medical personnel who give first aid treatment, hemophiliacs, dialysis patients, people who live with or spend much time with people with long-term hepatitis B infections, people with multiple sex partners, men who have sex with men, sex workers, injection drug abusers, and people traveling to high-risk areas.

Vaccines may not fully protect everyone who receives them.

Indications

The following indications are listed for Engerix-B Pediatric-Adolescent:

  • Hepatitis B Vaccination

Also known as: Vaccination To Prevent Hepatitis B Infection.

Dosing

Dosage recommendations for hepatitis B vaccine vary depending on the specific preparation used, the recipient's age, the HBsAg status of the mother (for neonates), and the presence of underlying disease.

Because the recommended doses for each vaccine are different, dosage recommendations for the specific preparation used should be followed.

In general, the various brands of age-appropriate hepatitis B vaccines are interchangeable within an immunization series; however, adolescents who start their vaccination series with the adult formulation of Recombivax HB(R) cannot complete the series with the adult formulation of Engerix-B(R), and patients who start their vaccination series with Heplisav-B(R) should complete it with the same product or receive a 3-dose series rather than the 2-dose series that is used with Heplisav-B(R).

The complete hepatitis B vaccine series must be administered to ensure optimal protection. Refer to guidance for specific recommendations if there are interruptions or delays in dosing.

Booster doses of hepatitis B vaccine are not recommended for immunocompetent individuals. Consult expert guidelines for booster dose recommendations (when anti-HBsAg antibody levels decline to <10 mIU/mL) for patients receiving hemodialysis in outpatient centers, pediatric patients with HIV, and other immunocompromised patients with an ongoing risk for HBV exposure.
