I had the twinrix shot for Hep A and B about 5 years ago and I was an adult at that time. How often do I need the booster?
There is no current recommendation for a booster dose of Twinrix (combined hepatitis A and hepatitis B) vaccine for adults who received all three doses of the Twinrix vaccine according to the standard schedule. For adults who received Twinrix on the rapid dosing schedule, a reinforcing dose is recommended 12 months after the first dose.
We recommend that you have your health care provider review your immunization record to determine whether or not you require another dose of the Twinrix vaccine.
