The hepatitis B vaccination is typically given as a course of three doses, administered at 0, 1, and 6 months — and for most healthy adults, this primary course provides long-lasting, often lifelong, protection. Some accelerated schedules are available for those travelling at short notice, compressing the course into as little as three weeks with a booster at 12 months. Whether a booster is needed after the primary course depends on individual factors such as age, immune response, and occupational or ongoing risk. The team at Edinburgh Travel Clinic take the time to understand your individual health history and travel plans, so you can be confident you’re leaving home with exactly the right level of protection.

Key Takeaways
- The standard hepatitis B vaccination course is three doses given at 0, 1, and 6 months.
- Accelerated schedules (0, 7, 21 days + booster at 12 months) are available for last-minute travellers.
- Most healthy adults who complete the primary course are protected for life without a routine booster.
- Healthcare workers and those with ongoing exposure risk may require antibody testing to confirm immunity.
- Hepatitis B vaccination is strongly recommended for travel to many parts of Asia, Africa, Eastern Europe, and South America.
- A combined hepatitis A and B vaccine (Twinrix) is available for eligible travellers, reducing the number of injections needed.
What Is Hepatitis B and Why Should Travellers Be Vaccinated?
Hepatitis B is a serious viral infection that affects the liver and is transmitted through contact with infected blood or bodily fluids — including unprotected sex, contaminated needles, and medical or dental procedures carried out without adequate infection control. It is estimated that over 250 million people worldwide are living with chronic hepatitis B infection, with the highest prevalence found across sub-Saharan Africa, Southeast Asia, and parts of the Pacific.
For travellers, the risks are real and varied. Even those not planning high-risk activities can be exposed through seemingly routine situations: a road traffic accident requiring emergency medical care abroad, a visit to a local dentist, or a tattoo or piercing obtained without sterile equipment. The hepatitis B vaccine is one of the most effective vaccines ever developed, with a protection rate of over 95% in healthy adults — making it an essential consideration for any international traveller.
The Standard Hepatitis B Vaccination Schedule
The primary course of the hepatitis B vaccine consists of three injections. The standard schedule is:
Standard Schedule: Dose 1 at Day 0 → Dose 2 at 1 month → Dose 3 at 6 months
Accelerated Schedule: Dose 1 at Day 0 → Dose 2 at Day 7 → Dose 3 at Day 21 → Booster at 12 months
Super-Accelerated Schedule: Three doses over 21 days — suitable only for those with imminent travel and ongoing risk, with a 12-month booster required to consolidate immunity.
The accelerated and super-accelerated schedules are particularly useful for travellers who have left vaccination planning to the last minute. Whilst they do offer earlier protection, it is worth noting that the antibody levels produced may be slightly lower initially than those achieved with the standard schedule. The 12-month booster is therefore essential in these cases to ensure long-term protection. Call us to book a consultation today and check your vaccination status.
Do You Need a Hepatitis B Booster?
Current evidence suggests that healthy adults who complete the full primary hepatitis B vaccination course can expect long-lasting protection – with most studies indicating immunity is maintained for decades and likely lifelong in the majority of cases. Routine booster doses are not currently recommended for healthy individuals in the general population who have responded well to the primary course.
However, certain groups may require antibody testing — known as anti-HBs titre testing — to confirm that an adequate immune response has been achieved. These groups include healthcare workers, those who are immunocompromised, individuals over the age of 40 (who may have a lower immune response to vaccination), and those with ongoing occupational or behavioural risk of exposure. If antibody levels are found to be below the protective threshold, a booster dose or repeat course may be recommended.
If you received your hepatitis B vaccination many years ago and are unsure of your current immunity status, a simple blood test can provide clarity. Our travel health clinicians can arrange this test and interpret the results in the context of your specific travel or occupational risks.
Who Should Have the Hepatitis B Vaccine?
Hepatitis B vaccination is recommended for a wide range of individuals, including — but not limited to — the following groups:
Travellers visiting high-prevalence regions such as Southeast Asia, sub-Saharan Africa, Central Asia, Eastern Europe, and South America should seriously consider vaccination, particularly if they plan to travel for extended periods, work in healthcare settings abroad, or engage in activities that carry a higher risk of exposure.
Healthcare and social care workers are routinely offered hepatitis B vaccination as part of their occupational health programme in the UK, given their risk of exposure to blood and bodily fluids. People who inject drugs, those with multiple sexual partners, and individuals with chronic liver or kidney disease are also among the priority groups for vaccination.
Infants and children in the UK are now routinely offered hepatitis B vaccination as part of the NHS childhood immunisation programme, introduced in 2017. If you or your child were not vaccinated as part of this programme, it is never too late to catch up. Contact us to get vaccinated before you travel.
Hepatitis A and B Combined Vaccine: Twinrix
If you need protection against both hepatitis A and hepatitis B before you travel, Twinrix – the combined vaccine – means you can achieve dual cover with fewer injections and less hassle. Twinrix is administered as a course of three doses on the same standard 0, 1, and 6-month schedule, providing dual protection with fewer injections. An accelerated Twinrix schedule is also available for those with limited time before travel.
Hepatitis A is transmitted through contaminated food and water and is one of the most common vaccine-preventable infections in travellers. Combining both vaccines not only simplifies the vaccination process but can also be more cost-effective for those requiring protection against both infections. Our travel health clinicians will advise whether Twinrix is the most appropriate option based on your destination and medical history.
Frequently Asked Questions
Whether you’re new to travel vaccinations or simply want to brush up on the facts, we’ve pulled together the questions we hear most often about hepatitis B – and if yours isn’t on the list, just get in touch.
How long does the hepatitis B vaccine last?
Studies show that protection following a completed primary course lasts at least 20–30 years and is considered lifelong for most healthy adults. Routine boosters are not recommended for the general population, though healthcare workers and those with ongoing risk may require antibody testing to confirm continued immunity.
Can I get the hepatitis B vaccine if I’m already infected?
The hepatitis B vaccine will not treat or cure an existing hepatitis B infection and should not be given to someone who is already chronically infected. A blood test is recommended before vaccination if there is any suspicion of prior exposure or existing infection.
Is the hepatitis B vaccine available on the NHS?
The hepatitis B vaccine is available on the NHS for certain high-risk groups, including healthcare workers, people who inject drugs, and those with chronic liver disease. If you’re looking to get vaccinated ahead of travel, a private travel health clinic like Edinburgh Travel Clinic is the most straightforward route to accessing the hepatitis B vaccine quickly and conveniently.
What are the side effects of the hepatitis B vaccine?
The hepatitis B vaccine is generally very well tolerated; the most common side effects are mild soreness, redness, or swelling at the injection site. Systemic reactions such as mild fever or fatigue are less common and typically resolve within 24–48 hours.
Can I have the hepatitis B vaccine whilst pregnant?
The hepatitis B vaccine is not a live vaccine and is not considered harmful during pregnancy; however, vaccination during pregnancy should always be discussed with a healthcare professional who can weigh up the risks and benefits based on individual circumstances. Where the risk of exposure is high, vaccination may still be recommended.
What happens if I miss a dose in my hepatitis B vaccination course?
If you miss a dose, you do not need to restart the course from the beginning — simply continue from where you left off as soon as possible. Our travel health clinicians can advise on the most appropriate timing for remaining doses based on how much of the course you have already completed.
