Hepatitis A Vaccine
Hepatitis A is one of the most common vaccine-preventable infections among travellers. A single dose provides solid protection for up to a year, and a booster at 6–12 months extends that to around 25 years.
What is hepatitis A?
Hepatitis A is a viral liver infection spread through contaminated food and water — particularly raw shellfish, salads, and street food in areas with poor sanitation. Symptoms include fatigue, nausea, jaundice, and abdominal pain, and can last several weeks.
Who needs this vaccine?
- Travellers to Asia, Africa, Central and South America, Eastern Europe, and the Middle East
- Anyone eating local food or drinking tap water in higher-risk areas
- Backpackers and those staying in budget accommodation
- Travellers visiting friends and relatives in affected regions
Doses & schedule
A single dose gives good protection from around 2 weeks after injection and lasts approximately 12 months. A booster given 6–12 months later extends protection to around 25 years for most people. If you're travelling soon, even a dose close to departure provides some protection.
