What is a hepatitis B vaccine?

A hepatitis B vaccine prevents hepatitis B virus infection (HBV). Engerix-B, Heplisav-B, and Recombivax HB (all brand names) are examples of hepatitis B vaccines approved by the U.S. Food and Drug Administration (FDA). Engerix-B and Recombivax HB are both approved for use in people of all ages. Heplisav-B is approved for use in adults 18 years of age and older.

HBV can be an opportunistic infection (OI) of HIV. An OI is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as people with HIV—than in people with healthy immune systems. To learn more about OIs, read the HIVinfo What is an Opportunistic Infection? fact sheet. To learn how HIV and HBV infection are connected, read the HIVinfo HIV and Hepatitis B fact sheet.

The Guidelines for the Prevention and Treatment of Opportunistic Infections in Adults and Adolescents with HIV and the Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Exposed and HIV-Infected Children include recommendations on the use of hepatitis B vaccines in people with HIV.

What should I tell my health care provider before receiving a hepatitis B vaccine?

Before receiving a hepatitis B vaccine, tell your health care provider:

  • If you are allergic to yeast or any other ingredient in a hepatitis B vaccine; latex; or any medicines. Tell your health care provider if you have ever had any reactions to a previous dose of a hepatitis B vaccine.
  • About any medical conditions you have or have had.
  • About any health conditions that may prevent you from receiving medicine by injection.
  • If you are pregnant or plan to become pregnant. Talk to your health care provider about the risks and benefits of getting a hepatitis B vaccine during pregnancy. The Guidelines for the Prevention and Treatment of Opportunistic Infections in Adults and Adolescents with HIV may include other recommendations on hepatitis B vaccination during pregnancy. Please refer to these guidelines for additional information.
  • If you are breastfeeding or plan to breastfeed. For women with HIV in the United States, the Guideline does not recommend breastfeeding. Before your baby is born, or if you are already breastfeeding, talk to your health care provider to discuss alternative options for feeding your baby.
  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Hepatitis B vaccines may affect the way other medicines or products work, and other medicines or products may affect how hepatitis B vaccines work. Ask your health care provider if there are interactions between hepatitis B vaccines and the medicines you take.

Ask your health care provider about possible side effects from getting a hepatitis B vaccine. Your health care provider will tell you what to do if you have side effects.
