Whether you need one or both hepatitis vaccines depends on where you’re travelling, what you plan to do and your health history. It’s easy to assume that one vaccine is enough, but for some trips, you may need protection against both. Understanding the Hepatitis A vs B vaccine difference can help you work out which vaccine is right for your journey.
What Is the Difference Between Hepatitis A and Hepatitis B?
Although both infections affect the liver, Hepatitis A and Hepatitis B are caused by different viruses and spread in different ways. Hepatitis A is mainly caught through contaminated food and water. Hepatitis B spreads through infected blood and bodily fluids, per the NHS.
This means the vaccine recommended for you isn’t based on your destination alone. Your travel plans and the activities you’re likely to take part in also matter.
Hepatitis A Vaccine for Travel
The Hepatitis A vaccine is recommended for many travellers visiting countries where the risk of Hepatitis A is higher. A single dose provides protection for around one year, while a booster can extend protection to over twenty years, according to the NHS.
Who Should Have the Hepatitis A Vaccine?
The Hepatitis A vaccine is worth considering if you are:
- Travelling to South Asia, sub-Saharan Africa, Central America, or parts of Eastern Europe.
- Likely to eat street food or travel in areas where sanitation may be limited.
- Working in healthcare or food preparation settings abroad.
Hepatitis B Vaccine for Travel
The Hepatitis B vaccine is recommended based on activities and exposure risk rather than destination alone. The WHO confirms a completed course can provide lifelong protection.
Who Should Have the Hepatitis B Vaccine?
The Hepatitis B vaccine may be recommended if you’re:
- Planning a long-stay trip, gap year, or volunteering abroad.
- Likely to need medical or dental treatment in a country with lower standards.
- Travelling to parts of Asia or sub-Saharan Africa where Hepatitis B rates are high.
- At risk of blood-to-blood contact through work or planned activities.
Do You Need Both Hepatitis Vaccines to Travel?
Not everyone needs both vaccines, but they may be recommended for travellers heading to areas where both infections pose a risk. Do I need hepatitis A and B vaccine? is a common question at travel clinics, particularly for longer trips.
What About the Combined Hepatitis A and B Vaccine?
If you need protection against both infections, there is a combined option. Twinrix protects against both Hepatitis A and Hepatitis B in one course.
It is normally given as three doses over six months, although an accelerated schedule is available if you’re travelling soon. The most suitable schedule will depend on how much time you have before departure.
