Hepatitis A vaccination protects against a viral liver infection spread through contaminated food and water. It is recommended for travellers visiting parts of Africa, Asia, the Middle East, and Central and South America. A pre-travel consultation reviews your itinerary to confirm whether hepatitis A vaccination is advised.
What Is Hepatitis A?
Hepatitis A is a viral infection of the liver, spread through contaminated food or water, or close contact with an infected person. It causes symptoms such as fever, tiredness, nausea, abdominal pain and jaundice (yellowing of the skin and eyes). Most people recover fully within a few months, though it can occasionally cause more serious illness.
Who Should Consider Vaccination?
Vaccination is recommended for travellers visiting countries where hepatitis A is common, including parts of Africa, Asia, the Middle East, and Central and South America, particularly if staying in areas with limited sanitation. It may also be considered for those with certain long-term health conditions, or specific occupational risks.
Vaccination Schedule
Hepatitis A vaccine is usually given as a single injection, ideally at least two weeks before travel, providing protection for around a year. A booster dose given 6 to 12 months later extends protection for up to 25 years. Combined hepatitis A and typhoid, or hepatitis A and B, vaccines are also available where relevant.
Food and Water Precautions
Vaccination reduces but does not eliminate the risk of hepatitis A. Following safe food and water practices, such as drinking bottled or treated water, washing hands thoroughly, and avoiding uncooked food from unreliable sources, remains important even after vaccination.
Frequently Asked Questions
How long before travel should I have the hepatitis A vaccine?
Ideally at least two weeks before departure, to allow protection to develop, though some protection may still be gained closer to travel.
How long does hepatitis A vaccine protection last?
A single dose protects for around a year; a booster dose 6 to 12 months later extends protection for up to 25 years.
Is hepatitis A vaccination available on the NHS?
Hepatitis A vaccination may be available free through the NHS for certain risk groups, or privately through a travel clinic. Your clinician will confirm eligibility during consultation.
Can hepatitis A vaccine be given with other travel vaccines?
Yes, it can usually be given alongside other travel vaccines at the same appointment, subject to clinical assessment.
Does the vaccine mean I no longer need to be careful with food and water?
