Hepatitis A and B Vaccination (TWINRIX®)

Houston Center for Infectious Diseases provides Twinrix to prevent the Hepatitis A and B:

  • The Twinrix® vaccine works by helping your body produce its own protection (antibodies) against hepatitis A and B.

  • Twinrix® may be used in adults, adolescents, and children at least 1 year of age.

  • Twinrix® is administered as an intramuscular injection by a healthcare professional.

Twinrix® is the only dual hepatitis A and B vaccine.

People who have a fever or anything more serious than a minor cold should postpone vaccination. Pregnant women should also delay vaccination, unless immediate vaccination is recommended by a doctor.

For maximum protection you should have the 3 doses recommended by Twinrix®

The hepatitis A vaccine also comes in a combination form, containing both hepatitis A and B vaccine, that can be given to persons 18 years of age and older. This form is given as three shots, over a period of six months or as three shots over one month and a booster shot at 12 months.
