Hepatitis B Vaccine: Who Needs It and Why

Hepatitis B is a serious liver infection caused by the hepatitis B virus. Chronic hepatitis B can lead to cirrhosis, liver failure, and liver cancer. Worldwide, it is a major cause of liver disease mortality. The hepatitis B vaccine is safe, effective, and provides long-lasting protection against infection. It is one of the recommended adult vaccines that many people may not have received. Hepatitis B is transmitted through contact with blood, sexual contact, and from mother to child during childbirth. Sharing needles or syringes, unprotected sex with an infected person, needlestick injuries in healthcare settings, and using contaminated medical equipment are the primary routes of transmission in adults. Infants born to infected mothers have a high risk of becoming chronically infected without appropriate preventive measures at birth. Hepatitis B vaccination has been recommended for all infants in the United States since 1991, with a three-dose series starting at birth. Despite this, many adults born before universal infant vaccination have never been vaccinated and may be at risk. The CDC recommends hepatitis B vaccination for all unvaccinated adults up to age 59. Adults 60 and older should also discuss vaccination with their healthcare provider. Vaccination is especially recommended for adults with risk factors including multiple sexual partners, injection drug use, liver disease, diabetes, kidney disease, HIV, and healthcare workers.

The hepatitis B vaccine series requires two, three, or four doses depending on the vaccine formulation. A combination hepatitis A and B vaccine is available for adults needing protection against both. After completing the vaccine series, testing for immunity is recommended only for specific high-risk groups such as healthcare workers and immunocompromised individuals. The hepatitis B vaccine is safe with excellent efficacy. It provides over 90 percent protection in healthy adults. For people who do not respond to the standard vaccine series due to immunosuppression or other factors, alternative higher-dose schedules may be used.
