Hepatitis A Vaccination doesn’t get talked about as much as some of the more dramatic travel health risks, but it’s one of the most common vaccine-preventable diseases affecting travellers worldwide. You don’t need to be trekking through remote villages to be exposed either; contaminated food or water at an all-inclusive resort, or even food served on a cruise ship, can be enough.

At our travel clinic in Manchester, Hepatitis A vaccination is one of the most frequently recommended travel jabs we discuss with patients, and for good reason. Here’s what it actually protects against, who needs it, and when to get it sorted before you fly.

What Is Hepatitis A?

Hepatitis A is a viral infection that attacks the liver. It’s spread through the faecal-oral route, most commonly by consuming food or water contaminated with the virus, or through close person-to-person contact.

Most healthy people recover fully without lasting liver damage, but the illness itself can be genuinely unpleasant, and there’s no specific antiviral treatment once you’re infected. Severe complications, including liver failure, are more common in older adults and people with existing liver conditions, which is why prevention through vaccination is so strongly emphasised.

Symptoms of Hepatitis A

Symptoms typically appear two to seven weeks after exposure and can include:

• Fatigue
• Nausea and vomiting
• Abdominal pain, particularly around the liver
• Loss of appetite
• Jaundice (yellowing of the skin and eyes)
• Dark urine and pale stools

Some infections, particularly in young children, can be mild or even without symptoms altogether, which means the virus can still spread within a household or travel group without anyone realising there’s a problem.

Where Is the Risk Highest?

Hepatitis A vaccination is recommended for travel to most destinations outside North America, Western Europe, Australia, and New Zealand. Risk is generally highest in areas with less developed sanitation infrastructure, including large parts of Asia, Africa, and Central and South America.

It’s worth being realistic about how this risk actually shows up in practice. You don’t need to be eating street food or staying somewhere basic to be exposed. Contaminated ice, salad washed in local water, or shellfish, even at a well-reviewed resort, can carry the same risk as anywhere else in a higher-risk region.

Who Should Get the Hepatitis A Vaccine?

Hepatitis A vaccination is generally recommended for travellers aged six months and older heading to areas of intermediate or high risk. It’s a particularly important discussion for:

• Anyone travelling to Asia, Africa, or Central and South America, regardless of how long the trip is or how comfortable the accommodation
• Backpackers and adventure travellers, where exposure to varied food and water sources is higher
• People visiting friends and relatives abroad, who often stay longer and eat more like locals than typical tourists
• Older travellers or those with existing liver conditions, given the higher risk of complications
• Anyone unsure whether they were vaccinated or infected as a child, since this affects whether vaccination is actually needed

How the Vaccine Works and When to Get It

The hepatitis A vaccine is typically given as a two-dose course. The first dose provides good protection within about two to three weeks, while the second dose, usually given between six months and three years later, extends protection long-term.

Because of this timing, it’s best to book your Hepatitis A vaccination appointment several weeks before you travel wherever possible, ideally around six to eight weeks ahead, to make sure you have time to build protection before you fly. That said, even a single dose shortly before a trip still offers meaningful protection, so it’s always worth asking rather than assuming it’s too late.

Other Ways to Reduce Your Risk

Vaccination is the most reliable protection, but sensible food and water precautions still matter, particularly in the window before full immunity develops:

• Stick to bottled or properly treated water, and avoid ice unless you’re confident of its source
• Be cautious with raw fruit and vegetables unless washed in clean water or peeled yourself
• Avoid food from street vendors or buffets that may not have been kept properly hot or cold
• Wash your hands regularly, especially before eating and after using the toilet
