The hepatitis A vaccine is recommended for anyone at increased risk of exposure to the hepatitis A virus — including travellers to certain countries, people with chronic liver disease, and individuals in close contact with someone who has been diagnosed with hepatitis A. In the UK, the NHS also recommends the vaccine for people who work with hepatitis A in a laboratory setting, those at risk through sexual behaviour, and people who inject drugs. At Perfect Meds, our GPhC-regulated pharmacists can assess your personal circumstances and advise whether the hepatitis A vaccine is right for you, providing clear, expert guidance every step of the way.

The Importance of Hepatitis A Vaccination
Hepatitis A is a contagious liver infection caused by the hepatitis A virus (HAV). Unlike hepatitis B and C, it does not cause chronic liver disease, but it can still lead to severe illness lasting several weeks or even months. The virus spreads primarily through contaminated food and water, or through close contact with an infected person — making it particularly prevalent in regions with poor sanitation infrastructure.
Symptoms of hepatitis A include jaundice (yellowing of the skin and eyes), fatigue, abdominal pain, nausea, and dark urine. While most people make a full recovery, older adults and those with underlying liver conditions can experience life-threatening complications. Vaccination is by far the most effective way to protect yourself — and with vaccines being safe, quick to administer, and long-lasting, there is every reason to ensure your immunity is up to date before any risk of exposure.
Who is Most at Risk of Hepatitis A?
Certain groups face a significantly higher risk of contracting hepatitis A and should consider vaccination a priority. Travellers heading to regions with a higher prevalence of hepatitis A — such as sub-Saharan Africa, South and Southeast Asia, parts of the Middle East, Central America, and Eastern Europe — are among the most frequently vaccinated. The virus is often found in local water supplies and can contaminate fresh produce and shellfish, making exposure a real and unpredictable risk even for careful travellers.
Beyond travel, the UK’s NHS identifies several additional at-risk groups. Men who have sex with men (MSM) face an elevated risk due to close personal contact. People who inject drugs — whether recreational or otherwise — are also at higher risk due to shared equipment and associated lifestyle factors. Individuals working in sewage treatment, food handling, or healthcare environments may encounter the virus professionally. Anyone in close household or sexual contact with a confirmed hepatitis A case should be vaccinated urgently.
When to Book Your Hepatitis A Vaccine?
Ideally, the hepatitis A vaccine should be given at least two weeks before potential exposure — making it essential to plan ahead before international travel. However, it can offer some protection even if given on the day of departure, so it is never too late to seek vaccination. For children and adults who have not previously been vaccinated, the course consists of two doses: an initial dose followed by a booster dose six to twelve months later. Together, a completed two-dose course is expected to provide protection for at least 25 years and potentially lifelong.
If you are travelling and have previously received a full two-dose course of the hepatitis A vaccine, you are likely still protected and may not require a booster. A healthcare professional can review your vaccination history and advise accordingly. Combination vaccines — such as those that protect against both hepatitis A and typhoid, or both hepatitis A and hepatitis B — are also available and can reduce the number of injections required when multiple vaccinations are needed.

Is the Hepatitis A Vaccine Safe?
The hepatitis A vaccine has an excellent safety record and has been in use for over three decades. It is an inactivated vaccine, meaning it contains a killed form of the hepatitis A virus and cannot cause hepatitis A infection. It is safe for most people, including the elderly and those with compromised immune systems, though it should not be given to anyone who has had a confirmed severe allergic reaction (anaphylaxis) to a previous dose of the vaccine or any of its components.
The most commonly reported side effects are mild and temporary. These include soreness, redness, or swelling at the injection site, which typically resolves within a few days. Some people experience a mild headache, fatigue, or loss of appetite following vaccination. Fever and nausea are less common but do occur in a small number of recipients. Serious allergic reactions are extremely rare. It is always advisable to remain at the clinic for at least 15 minutes after any vaccination so that any immediate reactions can be monitored and managed promptly.
Every destination comes with its own set of health risks, and knowing which vaccines you need before you travel can make all the difference. Enter your destination below to get an instant overview of the travel vaccines that may be recommended for your trip:
Who Can Get the Hepatitis A Vaccine on the NHS?
In England, the hepatitis A vaccine is available free on the NHS for people who meet specific clinical or occupational criteria. Eligible groups include people with chronic liver disease (including those with hepatitis B or C, cirrhosis, or alcohol-related liver disease), people who are at occupational risk such as laboratory workers handling the virus, staff working in sewage systems, and certain individuals who are homeless or living in insecure housing. The vaccine may also be recommended on the NHS following a confirmed outbreak or exposure incident.
The hepatitis A vaccine is readily available through registered private travel clinics and pharmacies for those who do not qualify for NHS funding, including the majority of leisure travellers. At Perfect Meds, we offer transparent pricing and a straightforward booking process so you can secure your vaccination without delay.

Frequently Asked Questions
Whether you are planning a trip abroad or simply want to understand your options, these answers to the most common questions about the hepatitis A vaccine will help you make an informed decision about your health.
How long does the hepatitis A vaccine last?
A single dose of the hepatitis A vaccine begins to offer protection within 2–4 weeks and provides cover for approximately one year. After completing the full two-dose course with a booster given six to twelve months after the first injection, protection is expected to last for at least 25 years and potentially lifelong.
Can I get the hepatitis A vaccine if I am pregnant?
The hepatitis A vaccine is not a live vaccine and is therefore considered safe to use during pregnancy when the potential benefits outweigh any theoretical risks. If you are pregnant and believe you are at significant risk of hepatitis A, you should speak with your GP or a pharmacist who can weigh up the risks and benefits in your specific circumstances.
Is the hepatitis A vaccine the same as the hepatitis B vaccine?
No — they are distinct vaccines that protect against two different viruses. Hepatitis A is spread primarily through contaminated food and water, whereas hepatitis B is spread through blood, sexual contact, and from mother to child during birth. A combination vaccine called Twinrix is available, which protects against both hepatitis A and hepatitis B in a single injection.
Which countries require or strongly recommend the hepatitis A vaccine?
The hepatitis A vaccine is strongly recommended for travel to many parts of Africa, South and Southeast Asia, Central and South America, the Middle East, and parts of Eastern Europe. It is wise to check the specific travel health advice for your destination with a qualified pharmacist or travel health clinic well in advance of your trip.
How quickly does the hepatitis A vaccine take effect?
The hepatitis A vaccine begins to offer protection within approximately two weeks of the first dose, which is why vaccination at least two weeks before travel is recommended where possible. Some level of protection may begin even sooner, and the full immune response develops within four weeks of the first injection.
Can children receive the hepatitis A vaccine?
Yes — the hepatitis A vaccine is licensed for use in children aged one year and over. It is particularly recommended for children travelling to high-risk areas or who are otherwise in an at-risk category. The dosing schedule is the same as for adults: an initial injection followed by a booster dose six to twelve months later.
Stay Protected with the Hepatitis A Vaccine
The hepatitis A vaccine is a safe, highly effective, and long-lasting way to protect yourself from a potentially serious liver infection. Whether you are planning international travel, working in a high-risk environment, or simply want the peace of mind that comes from being vaccinated, getting immunised against hepatitis A is a straightforward and sensible precaution. With a completed two-dose course providing protection that can last 25 years or more, it is one of the most cost-effective health investments you can make.
