Talk to your health care provider for more information.

  • If you received the Twinrix® or other hepatitis B vaccine from your health care provider, it is recommended that you complete the vaccine series through your health care provider. Alternatively, you may choose to receive the hepatitis B only vaccine through Durham Region Health Department immunization clinics.
  • Routine booster shots are not recommended at this time.

Are there side effects with the vaccine?

  • The most common reported side effects are:
    • Redness, pain and swelling where the needle was given
    • Headache
    • Fatigue
  • Side effects are usually mild and last only a short time. A cold, wet compress applied to the injection site and/or acetaminophen can be used to help relieve pain, swelling, and/or mild fever after vaccination.
  • Severe allergic reactions after vaccination are very rare and may not be related to the vaccine. However, if you think a serious reaction is developing, seek medical attention right away. Any unusual or significant changes in your health or your child’s health after the immunization should be reported to a health care provider and the Health Department.

Who should NOT get the vaccine?

  • Anyone who has had a serious allergic reaction (called anaphylaxis) to a previous dose of hepatitis B vaccine.
  • People who are sick with a high fever or serious infection worse than a cold should wait until they feel better before getting the vaccine.
  • If you have any medical conditions, discuss the vaccine with a health care provider to determine if you should receive it.
  • People who are pregnant or breastfeeding should discuss the need for hepatitis B vaccine with their health care provider before vaccination.
  • Any component in a vaccine may be a potential allergen. The most common for hepatitis B are:
    • Latex (Recombivax® only)
      • Engerix®-B (latex-free) can be given as an alternative
    • Yeast
    • Thimerosal (Engerix®-B multi-dose vial only)
