hepatitis b

Hepatitis B is a serious liver disease caused by the hepatitis B virus (HBV). The Centers for Disease Control and Prevention (CDC) estimate that 78,000 new HBV infections occur each year. HBV is spread through contact with the blood or other body fluids of an infected person. HBV can be spread to others one to two months before and after the onset of symptoms.

Symptoms of illness, when present, generally begin about 90 days after infection. Initial symptoms (prodromal phase), which last from 3 to 10 days, are malaise, fever, headache, and myalgia. These symptoms are followed by the icteric phase. The icteric phase lasts 1 to 3 weeks and is characterized by jaundice, light or gray stools, and liver tenderness. As a person recovers, malaise and fatigue may persist for weeks or months. However, most infected infants and children have no symptoms and about 50% of infected adults also have no symptoms.

About 5% of all acute HBV infections progress to chronic infection. The risk of chronic infection is greatest in infants and younger children. For example, 30% to 50% of children infected with HBV between 1 year and 5 years of age become chronically infected. In contrast, only 5% of adults become chronically infected. People who are chronically infected do not have symptoms, but they are able to spread HBV to others and are called carriers. In addition, about 25% of persons with chronic HBV infection die prematurely from cirrhosis or liver cancer.

About the Vaccine

There are two hepatitis B vaccines: Recombivax HB and Engerix-B. Both are inactivated recombinant vaccines. They are available in both adult and pediatric formulations. In addition, Recombivax HB is available in a formulation for persons on dialysis. Hepatitis B vaccine is also commonly administered as a combination vaccine with DTaP, IPV, hepatitis A, and/or Hib vaccine.

Indications Contraindications and precautions
Child
  • All children should receive their first dose of hepatitis B vaccine at birth and have a complete vaccine series by 6-18 months of age.
  • Children and adolescents through 18 years of age who did not receive the vaccine then they were younger should also be vaccinated.
Adult

All unvaccinated adults at risk for HBV infection should be vaccinated. This includes:

  • military personnel
  • men who have sex with men
  • people with more than one sex partner within 6 months
  • people who inject street drugs
  • people with chronic liver or kidney disease
  • people who have jobs that expose them to human blood
  • household contacts and sexual partners of people infected with HBV
  • residents and staff in institutions for persons with developmental disabilities
  • people who travel to countries where hepatitis B is common
  • people with HIV infection
  • people recently diagnosed with a sexually transmitted disease
  • people 19 through 59 years of age with diabetes mellitus *
  • anyone else who wants to be protected from HBV infection
  • People who have had a severe allergic reaction to a previous dose of hepatitis B vaccine or a hepatitis B vaccine component.* If you are administering hepatitis B combined with other vaccines (DTaP, Hib, hepatitis A, and/or polio) also check for a history of severe allergic reaction to a previous dose of these vaccines.
  • People who are moderately or severely ill should wait until recovery before receiving any vaccine. Minor illnesses, such as a cold, are not a contraindication.

* Hepatitis B vaccine may be administered at the discretion of the healthcare provider to unvaccinated adults with diabetes mellitus who are 60 years of age and older.

* Some products may contain yeast, neomycin, and aluminum hydroxide. The tip cap and the rubber plunger of the needless prefilled syringes may contain dry natural latex rubber.
