Two Weeks Before Travel
Protection develops within about two weeks of the first dose.

One of the most commonly needed travel vaccines and one of the most effective. A first dose protects for about a year, and a booster six to twelve months later extends that to around 25 years. The travel consultation is free.
Hepatitis A is a viral liver infection caught from contaminated food and water. It rarely causes lasting liver damage, but it makes people genuinely unwell for weeks and sometimes months, with jaundice, exhaustion, nausea and abdominal pain. It gets more severe with age, so it is not a young traveller’s inconvenience.
The vaccine is highly effective, and the schedule is unusually good value. A single dose protects you for about a year, and a booster at 6 to 12 months extends that to at least 25 years, which for most travellers means one course covers a lifetime of trips. Protection from the first dose develops within about two weeks.
It is recommended for most destinations outside Western Europe, North America, Australia and New Zealand, which makes it the vaccine most travellers need and one of the easiest decisions in travel health.

Protection develops within about two weeks of the first dose.
This is the dose that takes you from one year of protection to 25 or more. It is easy to forget, so we record it and remind you.
Still have it. Antibody response begins before the two-week mark, and having the vaccine is clearly better than not.
Monday to Friday 8am to 7pm, Saturday 9am - 2pm.
Step 1
At least two weeks before travel, where possible.
Step 2
Your itinerary and other vaccination needs are reviewed.
Step 3
A single injection in the upper arm.
Step 4
Booked for 6 to 12 months later, which is what secures long-term protection.

Hepatitis A is caused by a virus spread through the faecal oral route, which in practice means contaminated food, water, ice and shellfish, and sometimes person to person contact. Symptoms appear two to six weeks after exposure: fatigue, nausea, loss of appetite, abdominal discomfort, dark urine and jaundice.
Two things about it are worth knowing. First, unlike hepatitis B and C, hepatitis A does not become chronic. You either recover fully or, very rarely, become seriously unwell in the acute phase. There is no long term carrier state. Second, and counter intuitively, it gets worse with age. Young children often have it with barely any symptoms, while adults, particularly over 50 or with existing liver disease, can be severely ill for months. So the argument for vaccination strengthens as you get older.
The vaccine is inactivated, not live, so it is suitable for immunosuppressed people and can be given in pregnancy where indicated. It is one of the most effective vaccines in routine use, with a single dose producing protective antibodies in almost everyone. The booster at 6 to 12 months is what converts short term protection into long term, and the evidence supports at least 25 years and probably lifelong protection after two doses. In practice, once you have had both doses, you are unlikely ever to need it again.
Combined vaccines. Hepatitis A is available combined with hepatitis B as a three dose course, and combined with typhoid as a single injection. Both are useful, because the destinations overlap almost entirely.

Hepatitis A vaccine is available free on the NHS at many GP practices. Along with typhoid and diphtheria, tetanus and polio, it is one of the few travel vaccines the NHS funds. Ask your practice first if you have time. Private vaccination is worth paying for when you cannot get an appointment before you travel, want a combined vaccine, or want everything done in one visit.
£50 per dose.
About a year after one dose, and at least 25 years after the booster.
Often yes, at GP practices. Worth asking them first.
Yes, with hepatitis B as a three-dose course, or with typhoid as a single injection.
It is not a live vaccine and can be given where indicated. Discuss it with us.
Yes.
One for short-term protection, and a booster at 6 to 12 months for long-term protection.
Two weeks ideally. Have it even if you are travelling sooner.
If you had both doses, almost certainly not. If you only had one, a booster is worthwhile even years later.
Usually a sore arm, sometimes mild fatigue or a headache for a day or two.
It does not become chronic, but it makes people unwell for weeks to months and is more severe with age or existing liver disease.
The vaccine is highly effective, but those precautions protect you against typhoid and travellers’ diarrhoea too, so they remain worth following.
Book a same-day appointment. One injection now, a booster in 6 to 12 months, and you are protected for decades.
