Hepatitis A is a viral infection that affects the liver. It spreads most commonly through contaminated food or water, making it a particular risk in regions where sanitation standards differ from those in the UK. Most people recover fully, but the illness can be severe in older adults or those with underlying liver conditions, and there is no specific treatment.
Vaccination is the most reliable way to protect yourself before travelling to higher risk areas. A single dose provides rapid protection starting around 2 weeks after the injection and covers most holidays and short trips. A booster given 6 to 12 months later extends protection for up to 25 years, making it worth completing even after you return home.
Good food and water hygiene abroad remains important alongside vaccination. If you are unsure whether you need the hepatitis A vaccine for your trip, call us on 0161 437 2634 and our pharmacist will advise based on your destination and itinerary.
