At Brixton Travel Clinic, we regularly meet travellers who are unsure whether they need the Hepatitis A and B vaccine for their upcoming trip. Many people assume these infections are rare or only affect certain destinations, but the reality is that hepatitis A and hepatitis B remain two of the most common travel-related illnesses worldwide. Both are preventable, and both can cause serious long-term health problems if you are not protected.
This guide explains the real risks abroad, why vaccination is so important for London travellers and how our private travel clinic in Brixton can help you prepare safely and quickly. If you want personalised advice about the vaccine schedule, you can contact our team at any stage.
Why Travellers Need Protection
Hepatitis A and hepatitis B spread in different ways, but both are far more common in parts of Asia, Africa, Eastern Europe, South America and many popular tourist regions. Even destinations considered low risk can still expose travellers to unsafe food, contaminated water or poor hygiene practices.
Hepatitis A risks abroad include:
• contaminated food and drinking water
• ice cubes made from unclean water
• street food prepared without proper hygiene
• close contact in busy tourist areas
Hepatitis A can cause severe fatigue, fever, jaundice and digestive problems. The infection can disrupt travel plans for weeks and sometimes months.
Hepatitis B risks include:
• minor cuts or injuries while travelling
• medical or dental care abroad
• contact with infected bodily fluids
• sharing or cleaning piercings, razors or toothbrushes
Hepatitis B can lead to long-term liver disease and requires serious medical follow-up. Vaccination is the most reliable form of protection.
| Feature | Hepatitis A Vaccine | Hepatitis B Vaccine |
|---|---|---|
| Virus Type | Protects against hepatitis A virus, which mainly affects the liver through food and water contamination. | Protects against hepatitis B virus, which can cause acute and chronic liver disease. |
| Main Transmission Routes | Contaminated food, drinking water, ice and poor hand hygiene. | Blood and bodily fluids, unprotected sex, medical procedures, tattooing and shared needles or sharp items. |
| Who Commonly Needs It | Travellers to areas with poor sanitation, long-stay visitors, people staying with local families and those with chronic liver disease. | Healthcare workers, frequent travellers, long-stay visitors, people at risk of blood exposure and those with chronic liver disease. |
| Typical Schedule | One dose followed by a booster (often 6 to 12 months later) for long-lasting protection. | Three-dose course over several months, with accelerated options available for travellers. |
| Onset of Protection | Good protection usually develops within 2 to 4 weeks after the first injection. | Partial protection after the first doses, with stronger and longer protection after completing the full course. |
| Duration of Protection | Long term, often many years, especially after the booster dose. | Long term, often many years or more once the full course is completed. |
| Common Side Effects | Sore arm, mild redness or swelling at the injection site, occasional tiredness or headache. | Sore arm, mild redness or swelling at the injection site, occasional tiredness, headache or low-grade fever. |
| Travel Situations Where It Is Important | Trips where food and water hygiene may be uncertain, including resort stays, backpacking, visiting family and rural travel. | Trips where medical care quality is variable, higher risk activities, long stays abroad and areas with higher hepatitis B prevalence. |
| Combined Vaccines | Available as part of a combined hepatitis A and B vaccine, useful for travellers needing protection against both. | Also available in combination with hepatitis A in a single course for convenience. |

Why Last-Minute Vaccination Can Still Help
Ideally, travellers receive their hepatitis a and b vaccine well in advance. However, many London travellers visit us only days or weeks before departure. Fortunately, there are accelerated vaccine schedules that still offer rapid protection.
Fast protection is still possible because:
• the first dose starts building immunity quickly
• accelerated courses allow two or three doses in shorter intervals
• even partial protection is better than none
• long-term immunity can be completed after you return
This flexibility means you should never assume it is too late. If you are travelling soon, get in touch with our team and we will guide you on the fastest safe option.
Why London Travellers Are Often at Higher Risk
People travelling from London often visit multiple destinations on a single trip. Multi-stop itineraries, stopovers, volunteering placements and backpacking routes can significantly increase exposure to food contamination, minor injuries or unsanitary conditions.
Common higher-risk travel styles include:
• backpacking or hostels
• volunteering or charity projects
• work assignments abroad
• long-haul trips with multiple countries
• adventure holidays
• visiting friends and family in regions with higher infection rates
Our private travel clinic in Brixton helps travellers of all backgrounds, including families, solo travellers, business travellers, students and last-minute holidaymakers.
What to Expect from the Hepatitis A and B Vaccine
The hepatitis a and b vaccine is safe, well tolerated and widely used for global travel. It can be given as separate vaccines or combined, depending on your needs and timeline.
Typical schedules include:
• standard courses spread over several months
• accelerated courses for last-minute trips
• long-lasting protection after the full schedule is completed
Our clinicians will advise on the best course for your travel plans and medical history.
