How Long Does the Hepatitis A Vaccine Last? – Advice from Our Birmingham Travel ClinicThe hepatitis A vaccine provides excellent long-term protection against one of the world’s most common travel-related infections. A single initial dose offers protection for up to one year, while a booster dose given six to twelve months later can extend that protection for up to 25 years — and potentially even for life. The combined hepatitis A and B vaccine follows a similar schedule, offering robust, lasting immunity with a full course of doses. For most healthy adults, once the full two-dose course is complete, repeat vaccination is unlikely to be necessary. At Birmingham Travel Clinics, we help travellers of all ages understand exactly what protection they need before heading abroad.

What Is Hepatitis A and Why Should Travellers Be Concerned?
Hepatitis A is a viral liver infection caused by the hepatitis A virus (HAV). Unlike hepatitis B or C, it does not cause chronic liver disease, but it can still make you seriously unwell for several weeks — sometimes months. Symptoms include jaundice, fatigue, nausea, abdominal pain, and fever. In rare cases, particularly in older adults or those with pre-existing liver conditions, the illness can become severe and even life-threatening.
The virus is primarily spread through the faecal-oral route — most often through contaminated food or water. Travellers visiting regions with poor sanitation are at the highest risk, which includes large parts of South Asia, sub-Saharan Africa, Southeast Asia, and Central America. Even staying in tourist hotels doesn’t entirely eliminate the risk if local food or water is consumed.
How Does the Hepatitis A Vaccine Work?
The hepatitis A vaccine contains an inactivated (killed) form of the hepatitis A virus. When injected, it stimulates the immune system to produce antibodies against HAV without causing the disease itself. These antibodies remain in the bloodstream and are ready to fight off the real virus if you are ever exposed to it.
Protection begins to develop within two weeks of the first dose, which is why it’s important to plan your vaccination well ahead of travel. Ideally, you should receive the first dose at least two to four weeks before departure to ensure full protection is in place before you arrive at your destination.
The Hepatitis A Vaccination Schedule: One Dose vs. Two
The hepatitis A vaccine is given in a two-dose schedule. The first dose provides short-to-medium term protection, typically lasting around 12 months. The second dose — the booster — is given between six and twelve months after the first and dramatically extends that immunity. Research suggests the full two-dose course provides protection for at least 25 years, and many experts believe it may offer lifelong immunity.
If you have previously been vaccinated against hepatitis A, it is worth checking your records to confirm whether you received both doses and when. If you only ever had a single dose, getting the booster is a straightforward way to secure much longer-lasting protection.

Who Should Get the Hepatitis A Vaccine?
The hepatitis A vaccine is recommended for a wide range of people, including:
Travellers visiting countries with high or intermediate hepatitis A endemicity — this covers a vast portion of the globe. People with chronic liver disease, including those with hepatitis B or C, are especially encouraged to be vaccinated, as HAV infection can be more severe in these individuals. The vaccine is also recommended for men who have sex with men, people who inject drugs, and those who may have occupational exposure to the virus, such as sewage workers.
Children can also be vaccinated, and the hepatitis A vaccine is included in childhood immunisation programmes in some countries. In the UK, it is not part of the routine NHS schedule, so if your child is travelling to a high-risk area, a private travel clinic appointment is the best course of action.
Hepatitis A & B Combination Vaccine
If you require protection against both hepatitis A and hepatitis B, the combined vaccine Twinrix offers a convenient all-in-one solution. This is given as a three-dose course (at 0, 1, and 6 months) and provides long-term protection against both viruses. An accelerated schedule (0, 7, and 21 days, with a booster at 12 months) is also available for those who need protection at short notice. Speaking to a travel health specialist will help you determine the most suitable schedule for your travel plans.
Are There Any Side Effects?
The hepatitis A vaccine is considered very safe and well-tolerated. The most common side effects are mild and temporary, including soreness or redness at the injection site, headache, and mild fatigue. Serious reactions are extremely rare. As with all vaccines, our clinicians will advise you on what to look out for after your appointment.
Frequently Asked Questions
We know you may have questions – here are the answers to some of the most common ones we hear at Birmingham Travel Clinics.
Can I get the hepatitis A vaccine on the NHS?
The hepatitis A vaccine is not routinely available on the NHS for travel purposes, meaning most travellers will need to access it through a private travel clinic or pharmacy. However, it may be available on the NHS for individuals with specific medical conditions or occupational risks — speak to your GP for guidance.
How quickly does the hepatitis A vaccine start working?
Protection begins to develop within approximately two weeks of receiving the first dose of the hepatitis A vaccine. This is why it is strongly recommended to visit a travel clinic at least four to six weeks before your departure date.
Do I need a hepatitis A booster if I was vaccinated years ago?
If you completed the full two-dose course (initial dose plus booster), you are likely still protected and generally do not require a repeat course. If you are unsure of your vaccination history, a travel health specialist can review your records and advise accordingly.
Is the hepatitis A vaccine suitable for children?
Yes, the hepatitis A vaccine is safe and recommended for children travelling to high-risk destinations, and can typically be administered from the age of one year. A travel health consultation is the best way to confirm the correct dose and schedule for your child’s age and travel itinerary.
Can I still get hepatitis A if I have been vaccinated?
The hepatitis A vaccine is highly effective, with studies showing it to be over 95% effective after the first dose and near 100% effective after the complete two-dose course. While no vaccine guarantees absolute protection, vaccinated individuals are extremely well protected.
Can the hepatitis A vaccine be given at the same time as other travel vaccines?
Yes, the hepatitis A vaccine can generally be administered alongside other travel vaccines, including typhoid, yellow fever, and others, making it highly convenient to catch up on multiple immunisations in a single visit. Your travel health clinician will confirm the most appropriate timing and combinations based on your specific health profile and destination.

How Long Does the Vaccine for Hepatitis A Last? – Expert AdviceHepatitis A is a viral liver infection spread through contaminated food and water, making it a concern for travellers visiting certain parts of the world. Fortunately, the hepatitis A vaccine provides reliable protection against this disease. One of the most common questions we hear at Birmingham Travel Clinics is: how long does the vaccine for hepatitis A last? Understanding the duration of protection and whether you need booster doses is an important step in planning your travel health.
What Is Hepatitis A?
Hepatitis A is caused by the hepatitis A virus (HAV). It is highly contagious and usually spreads through food or water contaminated with infected faecal matter. Symptoms can include fever, nausea, abdominal pain, diarrhoea, dark urine, and jaundice (yellowing of the skin and eyes). While most people recover fully, the illness can be severe and cause long-term liver damage in rare cases. Prevention through vaccination is the best protection.
How Does the Hepatitis A Vaccine Work?
The hepatitis A vaccine is an inactivated vaccine, meaning it does not contain live virus. It works by stimulating your immune system to produce antibodies that protect against infection. This means if you are exposed to the virus after vaccination, your immune system will recognise it and fight it off effectively.
How Long Does Protection Last?
The duration of protection depends on whether you have received one or two doses of the vaccine:
After the First Dose
One dose of the hepatitis A vaccine provides good short-term protection, typically lasting around 12 to 18 months. This is suitable for last-minute travellers who need urgent protection before departure.
After the Second Dose
A booster dose is usually given 6 to 12 months after the first dose. With two doses, protection is long-lasting and can extend for at least 20 years, and often much longer. Many experts believe the vaccine may provide lifelong immunity after the full course.
Therefore, completing the two-dose course is the best way to ensure maximum and long-term protection against hepatitis A.
Who Should Get the Hepatitis A Vaccine?
The vaccine is recommended for anyone travelling to areas where hepatitis A is common, particularly in parts of:
- Africa
- South and Central America
- Asia
- Eastern Europe
It may also be advised for people with certain health conditions, such as chronic liver disease, or those working in environments where hepatitis A exposure is more likely.
Additional Protection Methods
While vaccination is the most reliable protection, you should also take steps to reduce your risk of exposure when travelling:
- Drink only bottled, boiled, or filtered water.
- Avoid ice unless you are sure it is made from safe water.
- Eat freshly cooked food and avoid raw or undercooked shellfish.
- Wash your hands regularly with soap and clean water.
- Peel fruit and vegetables before eating.
Combining vaccination with safe food and water practices gives you the best defence against hepatitis A.
