Combined Hepatitis A and B Vaccine
A combined vaccine can protect against both hepatitis A and hepatitis B in one course, convenient for travellers and others needing both.
What it protects against
It protects against both hepatitis A (spread through contaminated food and water) and hepatitis B (spread through blood and body fluids) — two viral liver infections — in a single combined course.
Who it's for
People who need protection against both infections, such as some travellers and certain risk groups, offering a convenient alternative to two separate vaccines.
How it works
It combines the inactivated hepatitis A virus and the hepatitis B surface protein, prompting protection against both, given as a course of doses.
Safety
Safety and side effects
It is safe and well tolerated, with common effects being soreness at the injection site, headache and tiredness. A travel clinic can advise on the best schedule before travel.

Answers
Combined Hepatitis A and B Vaccine: frequently asked questions
Why choose a combined hepatitis A and B vaccine?
If you need protection against both, a combined vaccine means fewer injections and appointments. A travel clinic or GP can advise whether it suits your needs and timing.
How soon before travel should I start the course?
Ideally several weeks ahead, as the combined course is given over time. Accelerated schedules exist for those travelling sooner, so seek advice early.
