Hepatitis B Quick Facts


hepatitis b virus

Hepatitis B

  • Hepatitis B (HBV) is a viral infection that infects the liver and requires direct contact with infected blood or other body fluids for transmission. Most acute hepatitis B infections do not persist but if the infection lasts 6 months or longer, it could lead to chronic liver disease, liver cancer and death.1 
  • Hepatitis B is not common in childhood in the U.S. and is not highly contagious in the same way that common childhood diseases like pertussis and chicken pox are contagious. In the U.S., hepatitis B is primarily an adult disease (ages 20-50) but the virus also can be transmitted from an infected mother to her newborn baby. Most people do not experience any symptoms during acute infection but may have symptoms, such as yellowing of the skin and eyes (jaundice), dark urine, extreme fatigue, nausea, vomiting and abdominal pain.2,3
  • While hepatitis B was not prevalent in the U.S. before childhood vaccination campaigns were introduced in 1991, historically it has been endemic in Asia and Africa. In 1991, there were 18,003 cases of hepatitis B reported in the U.S. out of a total U.S. population of 248 million. In 1996, there were 10,637 cases of hepatitis B reported in the U.S. with 279 cases reported in children under the age of 14.4
  • Worldwide, hepatitis B is the cause of up to 80 percent of liver cancer and an estimated 686,000 people die each year from acute or chronic hepatitis B around the world.5,6
  • In the U.S., individuals at highest risk for hepatitis B infection are those, who engage in risky behaviors such as illegal IV drug use, prostitution, men who have sex with men, heterosexuals with multiple sexual partners and people who have received blood transfusions using infected blood.7 Healthcare workers, who are exposed to infected blood or body fluids of patients through contact with needles or medical devices used on patients, or when breaches in proper hygiene and/or infection control practices occur, are at high risk for becoming infected with hepatitis B.8 In 2015, there were 3,370 acute cases of hepatitis B reported in the U.S.9  

Hepatitis B Vaccine 

  • There are five recombinant hepatitis B vaccines approved by the FDA for use in the U.S.: Engerix-B; Recombivax HB; Twinrix (combined with hepatitis A); and Pediarix (combined with diphtheria and tetanus toxoids, acellular pertussis adsorbed, and inactivated poliovirus).10 The fifth, Comvax (combined with Haemophilus Influenza Type B (HIB) and Meningococcal Protein) is an approved vaccine but production of the vaccine was discontinued in December 2014.11 The recombinant hepatitis B vaccine is created through genetic engineering of DNA by inserting a segment of the viral gene in a yeast cell.12
  • The CDC recommends that all infants be vaccinated with three doses of hepatitis B vaccine beginning at 12 hours of age with the last dose given before 18 months of age to prevent transmission by an infected mother to her newborn.13 The CDC also recommends hepatitis B vaccination for adults with diabetes; household and sexual contacts of people with chronic hepatitis B infection; healthcare workers; people at increased risk for hepatitis B virus exposure due to occupational, behavioral, or medical factors; and international travelers to countries with high or intermediate hepatitis B infection rates.  14
  • The primary reason that the CDC recommended hepatitis B vaccination for all newborns in the United States in 1991 is because public health officials and doctors could not persuade adults in high risk groups (primarily IV drug users and persons with multiple sexual partners) to get the vaccine.15,16 ,17
  • Despite hepatitis B affecting mainly adults (aged 20 to 50), by 2014, only 24.5 percent of U.S. adults over 19 years of age had received the vaccine. Further, only 60.7 percent of U.S. health care workers in 2014 had been vaccinated for hepatitis B.18 
  • As of August 2017, there had been 861 claims filed in the federal Vaccine Injury Compensation Program (VICP) for injuries and deaths following hepatitis B containing vaccinations, including 89 deaths and 772 serious injuries.19
  • Using the MedAlerts search engine, as of May 31, 2017 there had been a total of 83,585 adverse events following hepatitis B containing vaccinations reported to the federal Vaccine Adverse Events Reporting System (VAERS) since 1990, and 61,825 of the adverse events were associated with hepatitis B vaccine alone (not combined with other vaccines). There had been 16,435 serious adverse events reported to the Vaccine Adverse Events Reporting System (VAERS) in connection with Hepatitis B containing vaccines since 1990. Approximately 55% of those serious Hepatitis B vaccine-related adverse events occurring in children under 3 years old. Of these Hepatitis B-vaccine related adverse event reports to VAERS 1,857 were deaths, with 82%, or 1,524, of the deaths occurring in children under three years of age.

Search for Vaccine Reactions 

NVIC hosts MedAlerts, a powerful VAERS database search engine. MedAlerts examines symptoms, reactions, vaccines, dates, places, and more. 

Reporting a Vaccine Reaction 

Since 1982, the NVIC has operated a Vaccine Reaction Registry, which has served as a watchdog on VAERS. Reporting vaccine reactions to VAERS is the law. If your doctor will not report a reaction, you have the right to report a suspected vaccine reaction to VAERS. 

Vaccine Reaction Symptoms & Ingredients 

Our Ask 8, If You Vaccinate webpage contains vaccine reaction symptoms and more. Calculate vaccine ingredients for potential toxic exposures & print a vaccination plan with the Vaccine Ingredients Calculator.
