- In 2009, about 38,000 people became infected with hepatitis B.
- Each year about 2,000 to 4,000 people die in the United States from cirrhosis or liver cancer caused by hepatitis B.
- Loss of appetite
- Pain in muscles, joints, and stomach
- Diarrhea and vomiting
- Jaundice (yellow skin or eyes)
- Liver damage (cirrhosis)
- Liver cancer
- A baby whose mother is infected can be infected at birth
- Children, adolescents, and adults can become infected by:
- Contact with blood and body fluids through breaks in the skin such as bites, cuts, or sores
- Contact with objects that have blood or body fluids on them such as toothbrushes, razors, or monitoring and treatment devices for diabetes
- Having unprotected sex with an infected person
- Sharing needles when injecting drugs
- Being stuck with a used needle
- Babies normally get 3 doses of hepatitis B vaccine:
- 1st Dose: Birth
- 2nd Dose: 1-2 months of age
- 3rd Dose: 6-18 months of age
- Anyone through 18 years of age who didn't get the vaccine when they were younger should also be vaccinated.
- All unvaccinated adults at risk for hepatitis B infection should be vaccinated. This includes:
- Sex partners of people infected with hepatitis B
- Men who have sex with men
- People who inject street drugs
- People with more than one sex partner
- People with chronic liver or kidney disease
- People under 60 years of age with diabetes
- People with jobs that expose them to human blood or other body fluids
- Household contacts of people infected with hepatitis B
- Residents and staff in institutions for the developmentally disabled
- Kidney dialysis patients
- People who travel to countries where hepatitis B is common
- People with HIV infection
- Other people may be encouraged by their doctor to get hepatitis B vaccine; for example, adults 60 and older with diabetes. Anyone else who wants to be protected from hepatitis B infection may get the vaccine.
- Pregnant women who are at risk for one of the reasons stated above should be vaccinated. Other pregnant women who want protection may be vaccinated.
- Anyone with a life-threatening allergy to yeast, or to any other component of the vaccine, should not get hepatitis B vaccine. Tell your doctor if you have any severe allergies.
- Anyone who has had a life-threatening allergic reaction to a previous dose of hepatitis B vaccine should not get another dose.
- Anyone who is moderately or severely ill when a dose of vaccine is scheduled should probably wait until they recover before getting the vaccine.
- Soreness where the shot was given (up to about 1 person in 4).
- Temperature of 99.9°F or higher (up to about 1 person in 15).
- Look for anything that concerns you, such as signs of a severe allergic reaction, very high fever, or behavior changes.
- If you think it is a severe allergic reaction or other emergency that can't wait, call 9-1-1 or get the person to the nearest hospital. Otherwise, call your doctor.
- Afterward, the reaction should be reported to the Vaccine Adverse Event Reporting System (VAERS). Your doctor might file this report, or you can do it yourself through the "VAERS website":http://vaers.hhs.gov/index or by calling 1-800-822-7967.

What is hepatitis B?
Hepatitis B is a serious infection that affects the liver. It is caused by the hepatitis B virus.
Hepatitis B can cause:
Acute (short-term) illness. This can lead to:
Acute illness, with symptoms, is more common among adults. Children who become infected usually do not have symptoms.
Chronic (long-term) infection. Some people go on to develop chronic hepatitis B infection. Most of them do not have symptoms, but the infection is still very serious, and can lead to:
Chronic infection is more common among infants and children than among adults. People who are chronically infected can spread hepatitis B virus to others, even if they don't look or feel sick. Up to 1.4 million people in the United States may have chronic hepatitis B infection.
Hepatitis B virus is easily spread through contact with the blood or other body fluids of an infected person. People can also be infected from contact with a contaminated object, where the virus can live for up to 7 days.
Hepatitis B vaccine: Why get vaccinated?
Hepatitis B vaccine can prevent hepatitis B, and the serious consequences of hepatitis B infection, including liver cancer and cirrhosis.
Hepatitis B vaccine may be given by itself or in the same shot with other vaccines.
Routine hepatitis B vaccination was recommended for some U.S. adults and children beginning in 1982, and for all children in 1991. Since 1990, new hepatitis B infections among children and adolescents have dropped by more than 95% and by 75% in other age groups.
Vaccination gives long-term protection from hepatitis B infection, possibly lifelong.
Who should get hepatitis B vaccine and when?
Children and adolescents
Some babies might get 4 doses, for example, if a combination vaccine containing hepatitis B is used. (This is a single shot containing several vaccines.) The extra dose is not harmful.
Adults getting hepatitis B vaccine should get 3 doses -- with the second dose given 4 weeks after the first and the third dose 5 months after the second. Your doctor can tell you about other dosing schedules that might be used in certain circumstances.
Who should not get hepatitis B vaccine?
Your doctor can give you more information about these precautions.
Note: You might be asked to wait 28 days before donating blood after getting hepatitis B vaccine. This is because the screening test could mistake vaccine in the bloodstream (which is not infectious) for hepatitis B infection.
What are the risks from hepatitis B vaccine?
Hepatitis B is a very safe vaccine. Most people do not have any problems with it.
The vaccine contains non-infectious material, and cannot cause hepatitis B infection.
Some mild problems have been reported:
Severe problems are extremely rare. Severe allergic reactions are believed to occur about once in 1.1 million doses.
A vaccine, like any medicine, could cause a serious reaction. But the risk of a vaccine causing serious harm, or death, is extremely small. More than 100 million people in the United States have been vaccinated with hepatitis B vaccine.
What if there is a serious reaction?
What should I look for?
Signs of a severe allergic reaction can include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, and weakness. These would start a few minutes to a few hours after the vaccination.
What should I do?
VAERS is only for reporting reactions. They do not give medical advice.
The National Vaccine Injury Compensation Program
The National Vaccine Injury Compensation Program (VICP) is a federal program that was created to compensate people who may have been injured by certain vaccines.
Persons who believe they may have been injured by a vaccine can learn about the program and about filing a claim by calling 1-800-338-2382 or visiting the "VICP website":http://www.hrsa.gov/vaccinecompensation/index.html.
