Questions & Answers

Side Effects & Adverse Reactions

The vial stopper is latex-free. The tip cap and the rubber plunger of the needleless prefilled syringes contain dry natural latex rubber that may cause allergic reactions in latex sensitive individuals.

Hepatitis B has a long incubation period. Hepatitis B vaccination may not prevent hepatitis B infection in individuals who had an unrecognized hepatitis B infection at the time of vaccine administration. Additionally, it may not prevent infection in individuals who do not achieve protective antibody titers.

Uses

ENGERIX-B is indicated for immunization against infection caused by all known subtypes of hepatitis B virus. As hepatitis D (caused by the delta virus) does not occur in the absence of hepatitis B infection, it can be expected that hepatitis D will also be prevented by ENGERIX-B vaccination.

ENGERIX-B will not prevent hepatitis caused by other agents, such as hepatitis A, C, and E viruses, or other pathogens known to infect the liver.

Immunization is recommended in persons of all ages, especially those who are, or will be, at increased risk of exposure to hepatitis B virus,1 for example:

  • Infants, Including Those Born of HBsAg-Positive Mothers (See DOSAGE AND ADMINISTRATION.)
  • Adolescents (See CLINICAL PHARMACOLOGY.)
  • Healthcare Personnel: Dentists and oral surgeons.Dental, medical, and nursing students. Physicians, surgeons, and podiatrists. Nurses. Paramedical and ambulance personnel and custodial staff who may be exposed to the virus via blood or other patient specimens. Dental hygienists and dental nurses. Laboratory and blood bank personnel handling blood, blood products, and other patient specimens. Hospital cleaning staff who handle waste.
  • Selected Patients and Patient Contacts: Patients and staff in hemodialysis units and hematology/oncology units. Patients requiring frequent and/or large volume blood transfusions or clotting factor concentrates (e.g., persons with hemophilia, thalassemia, sickle cell anemia, cirrhosis). Clients (residents) and staff of institutions for the mentally handicapped. Classroom contacts of deinstitutionalized mentally handicapped persons who have persistent hepatitis B surface antigenemia and who show aggressive behavior. Household and other intimate contacts of persons with persistent hepatitis B surface antigenemia.
  • Subpopulations With a Known High Incidence of the Disease, such as: Alaskan Eskimos. Pacific Islanders. Indochinese immigrants. Haitian immigrants. Refugees from other HBV-endemic areas. All infants of women born in areas where the infection is highly endemic.
  • Individuals With Chronic Hepatitis C: Risk factors for hepatitis C are similar to those for hepatitis B. Consequently, immunization with hepatitis B vaccine is recommended for individuals with chronic hepatitis C.
  • Persons Who May Be Exposed to the Hepatitis B Virus by Travel to High-Risk Areas (See ACIP Guidelines, 1990.)
  • Military Personnel Identified as Being at Increased Risk
  • Morticians and Embalmers
  • Persons at Increased Risk of the Disease Due to Their Sexual Practices,1,16 such as: Persons with more than 1 sexual partner in a 6-month period. Persons who have contracted a sexually transmitted disease. Homosexually active males. Female prostitutes.
  • Prisoners
  • Users of Illicit Injectable Drugs
  • Others: Police and fire department personnel who render first aid or medical assistance, and any others who, through their work or personal life-style, may be exposed to the hepatitis B virus. Adoptees from countries of high HBV endemicity.
Use With Other Vaccines:

The ACIP states that, in general, simultaneous administration of certain live and inactivated pediatric vaccines has not resulted in impaired antibody responses or increased rates of adverse reactions.17 Separate sites and syringes should be used for simultaneous administration of injectable vaccines.

Other Information

ENGERIX-B [Hepatitis B Vaccine (Recombinant)] is a noninfectious recombinant DNA hepatitis B vaccine developed and manufactured by GlaxoSmithKline Biologicals. It contains purified surface antigen of the virus obtained by culturing genetically engineered Saccharomyces cerevisiae cells, which carry the surface antigen gene of the hepatitis B virus. The surface antigen expressed in Saccharomyces cerevisiae cells is purified by several physicochemical steps and formulated as a suspension of the antigen adsorbed on aluminum hydroxide. The procedures used to manufacture ENGERIX-B result in a product that contains no more than 5% yeast protein. No substances of human origin are used in its manufacture.

ENGERIX-B is supplied as a sterile suspension for intramuscular administration. The vaccine is ready for use without reconstitution; it must be shaken before administration since a fine white deposit with a clear colorless supernatant may form on storage.

ENGERIX-B is formulated without preservatives.

Pediatric/Adolescent:

Each 0.5-mL dose contains 10 mcg of hepatitis B surface antigen adsorbed on 0.25 mg aluminum as aluminum hydroxide. The pediatric formulation contains sodium chloride (9 mg/mL) and phosphate buffers (disodium phosphate dihydrate, 0.98 mg/mL; sodium dihydrogen phosphate dihydrate, 0.71 mg/mL).

Adult:

Each 1-mL adult dose contains 20 mcg of hepatitis B surface antigen adsorbed on 0.5 mg aluminum as aluminum hydroxide. The adult formulation contains sodium chloride (9 mg/mL) and phosphate buffers (disodium phosphate dihydrate, 0.98 mg/mL; sodium dihydrogen phosphate dihydrate, 0.71 mg/mL).
