Hepatitis B Vaccine Course: Timing, Options and Accelerated Schedules

The hepatitis B vaccine course is one of the most common things we're asked about at our travel clinic, and the question is nearly always about timing. "I fly in three weeks. Is it too late?" Usually, it isn't. Hepatitis B vaccination comes in several schedules, from a leisurely six months to a very rapid three weeks, and the right one depends on when you travel and why you need it. As pharmacist prescribers at Brookfield Pharmacy in Hucclecote, we've put together this guide to the hep B vaccine course: who it's for, the standard and accelerated schedules, what happens at the end, and what it costs in Gloucester.

What is hepatitis B, and how do travellers catch it?

Hepatitis B is a viral infection of the liver. It spreads through blood and body fluids, not through food or water like hepatitis A. The main routes are:

• Medical or dental treatment with equipment that isn't properly sterilised, including injections, drips, stitches and blood transfusions
• Tattoos, piercings, acupuncture and shaving with shared or reused needles and blades
• Unprotected sex with a new partner
• Sharing needles or other injecting equipment
• Contact with blood when helping someone who is injured

Many people who catch hepatitis B have no symptoms at first. Some develop jaundice, tiredness, nausea and abdominal pain. The bigger concern is that a proportion of adults, and most infants, go on to develop chronic infection, which can lead to cirrhosis and liver cancer years later. There is no cure for chronic hepatitis B, but the vaccine is safe, well tolerated and highly effective.

Hepatitis B is common across much of sub-Saharan Africa, East and South East Asia, the Pacific islands, parts of South America, the Middle East and Eastern Europe. Even in countries where it's less common, the risk comes from the activities above rather than the destination itself.

Who needs the hepatitis B vaccine for travel?

Not every holiday needs hep B vaccination. A short package holiday with no plans beyond the pool carries a low risk. We're more likely to recommend the course if you:

• Are travelling for a month or more, or making frequent shorter trips to higher-risk regions
• Are backpacking, volunteering or working abroad, especially in healthcare, teaching, aid work or childcare
• Have a medical condition that makes treatment abroad more likely, such as diabetes, heart disease or kidney disease
• Plan adventure activities with a real chance of injury: motorbiking, trekking, climbing, diving or contact sports
• May get a tattoo or piercing while away
• Might have a new sexual partner on your travels
• Are adopting or fostering a child from a country where hepatitis B is common
• Are a healthcare or laboratory worker and haven't already been vaccinated through your employer

If you were born in the UK after August 2017, you'll have had hepatitis B as part of the routine 6-in-1 childhood vaccine, so you're very likely already covered. Older children and adults usually aren't, unless they've been vaccinated for work.

Hepatitis B vaccine course: standard vs accelerated schedules

The hepatitis B vaccine is an inactivated vaccine given into the upper arm. It can't give you hepatitis B. The course is three or four doses depending on the schedule, and the main difference between schedules is how quickly you're protected.

The standard schedule: 0, 1 and 6 months

This is the textbook course and the one we suggest when there's no rush. You have two doses a month apart, then a third dose six months after the first. It gives the most durable response from three doses alone, with no extra booster needed for most people.

The accelerated schedule: 0, 1, 2 and 12 months

If you're travelling in the next two to three months, we compress the first three doses into two months. You're well protected after the third dose, but to lock in long-term immunity you need a fourth dose at 12 months. We'll book that in before you go so it doesn't get forgotten.

The very rapid schedule: 0, 7, 21 days and 12 months

For adults travelling at short notice, the three initial doses can be given on day 0, day 7 and day 21. This is the "I fly in a month" option. Most adults have good protection within a week or two of the third dose. As with the accelerated schedule, a 12-month booster completes the course. This schedule is licensed for adults aged 18 and over, so for children we use the accelerated 0, 1, 2 month course instead.

What if I can't finish the course before I travel?

Start anyway. Even one or two doses give partial protection, and the course doesn't have to be restarted if a dose is late. We'll give you a vaccination record to carry, and you can complete the remaining doses when you're home. For anything else you're short of time on, see our post on 12 common travel health mistakes.

Do I need a blood test at the end of the hepatitis B course?

For most travellers, no. The vaccine works in well over 90% of healthy adults, and a blood test isn't routinely needed after the course.

A blood test for hepatitis B antibodies is recommended one to four months after the final dose if you:

• Work in healthcare or a laboratory and have contact with blood or body fluids
• Have a weakened immune system, kidney disease or are on dialysis
• Are over 40, carry extra weight or smoke, as the vaccine response can be lower
• Will have long-term, ongoing exposure rather than a single trip

If the test shows you haven't responded fully, we can arrange a further dose or an extra course. For healthcare workers, your employer's occupational health team usually organises this test, and we're happy to provide your vaccination record for them.

How long does hepatitis B protection last?

Once you've completed a full course, including the 12-month booster for accelerated schedules, most healthy adults are protected for life. Current UK guidance doesn't recommend routine boosters for travellers with a normal immune system.

The exceptions are people with ongoing occupational risk, such as healthcare workers, who may be offered a single booster around five years after their primary course, and people with kidney disease or a weakened immune system, who are monitored with blood tests.

Side effects of the hepatitis B vaccine

Side effects are usually mild and short-lived: a sore, red arm for a day or two, tiredness, a headache or a mild temperature. Serious reactions are very rare. The vaccine can be given at the same appointment as other travel vaccines such as hepatitis A, typhoid and rabies, and it's suitable in pregnancy where there's a genuine risk of exposure.

There's also a combined hepatitis A and B vaccine, which saves injections if you need both. Ask at your consultation whether this is a good option for your trip.

How much does the hepatitis B vaccine course cost?

Hepatitis B vaccination for travel isn't funded by the NHS, so it's a private vaccine wherever you get it. The NHS does provide it free for specific risk groups, such as people who inject drugs, some healthcare workers and close contacts of someone with the infection. If you think you might qualify, speak to your GP.

At Brookfield Pharmacy the cost is:

That includes your travel consultation and risk assessment, and the price per dose is the same whichever schedule you choose. The 12-month booster on the accelerated and very rapid schedules is charged as an additional dose. For a full picture of what your trip might cost alongside hepatitis A, typhoid and malaria tablets, see our travel vaccine cost guide.

Getting the hepatitis B vaccine in Gloucester

You don't need a GP referral. Our pharmacist prescribers handle the whole course at Brookfield Pharmacy's travel clinic:

1. Book a travel consultation online or by phone. Ideally come six to eight weeks before you travel, but we can usually help at shorter notice using the rapid schedule.
2. Consultation: we go through your itinerary, activities, health and medicines, and agree which hep B schedule fits your travel date.
3. First dose on the day, if you're happy to go ahead, with the remaining doses booked at times that suit you.
4. Record card: you'll get a written record of each dose to carry with your passport and to show any future employer or clinic.
5. Everything else: any other vaccines or antimalarials are covered in the same appointment. For an overview of what else your destination may need, see our travel vaccinations guide.

We're a short drive from Gloucester city centre, Brockworth and Churchdown, with parking nearby.

Frequently asked questions

How quickly can I complete the hepatitis B vaccine course?

Adults can have the three initial doses in 21 days on the very rapid schedule (day 0, day 7 and day 21), with a booster at 12 months. If you've got two to three months, the accelerated 0, 1, 2 month schedule is a good option. Either way, you'll have useful protection before you fly.

Is the hepatitis B vaccine three doses or four?

Three on the standard 0, 1, 6 month schedule. Four on the accelerated and very rapid schedules, because the quicker initial doses need a 12-month booster to give long-term protection.

Do I need a booster for hepatitis B after five years?

Not if you're a healthy traveller who completed a full course. UK guidance doesn't recommend routine boosters for people with a normal immune system. Healthcare workers and people with kidney disease or a weakened immune system may need a booster or blood test, which we can advise on.

Can I get the hepatitis B vaccine for free on the NHS?

Not for travel. The NHS provides it free for defined risk groups, such as people who inject drugs, people with chronic liver or kidney disease, and close contacts of someone with hepatitis B. Children born after August 2017 have it as part of the routine 6-in-1 vaccine.

I missed my second hepatitis B dose. Do I have to start again?

No. The course never needs to be restarted. Come in for the missed dose as soon as you can and we'll adjust the timing of the remaining doses.
