Who Should Get the Hepatitis B Vaccine in Bangkok?
Vaccination is recommended for any unvaccinated adult travelling to or living in Thailand. Thailand’s background prevalence is 7 to 8 percent, far higher than most Western countries.
Travellers to Thailand
Recommended regardless of trip length. A motorbike accident, dental emergency, or sexual encounter creates real exposure opportunity.
Expats and Residents
Not vaccinated as a child? Thailand’s high prevalence makes vaccination a straightforward one-time investment in lifelong protection.
Healthcare Workers
Anyone in regular contact with blood or bodily fluids. Occupational exposure is a significant risk without vaccination.
Pregnant Women
Hepatitis B infection during pregnancy carries high transmission risk to the newborn. Vaccination is recommended for unvaccinated pregnant women at risk.
Tattoos, Piercings, Dental Work
Planning any procedure in Thailand? Blood-to-blood contact during these procedures carries transmission risk. Vaccinate before, not after.
Chronic Conditions
Diabetes, liver disease, or chronic kidney disease all increase the severity of hepatitis B infection if contracted.
Vaccinated as a child? A titer test at Doctor Bangkok confirms your immunity before any decision on boosting. We recommend testing rather than assuming.
Do You Need the Hepatitis B Vaccine in Thailand?
Yes, if you are not already vaccinated. Thailand has one of the highest hepatitis B prevalence rates in Southeast Asia, with approximately 7 to 8 percent of the population carrying the virus, compared to under 1 percent in most Western countries. The background exposure risk here is materially higher than at home.
Hepatitis B transmits through blood, sexual contact, and contaminated medical or dental equipment. For travellers and expats, common exposure routes include unprotected sex, tattoos or piercings, shared razors, and medical or dental procedures in facilities with lower sterilisation standards. The virus is 50 to 100 times more infectious than HIV. Vaccination before exposure is the only reliable protection.
Most adults who contract hepatitis B clear the infection naturally. However, approximately 5 percent develop chronic hepatitis B, which can progress to cirrhosis and liver cancer over decades. There is no cure for chronic infection. The vaccine provides lifelong protection from a single completed course.
Is the Hepatitis B Vaccine Necessary for a Short Trip?
Yes. The hepatitis B vaccine is recommended for all unvaccinated adults travelling to Thailand regardless of trip length, by the WHO, the CDC, and the Thai Ministry of Public Health. A single sexual encounter, a motorbike accident requiring stitches, or a dental emergency creates a real exposure opportunity.
Vaccination is a one-time investment that protects you for life. If you were vaccinated as a child or previously completed a course, you may already have lasting immunity. A hepatitis B antibody titer blood test confirms whether your immunity is still active. Doctor Bangkok can run this test on the same visit before administering any unnecessary doses.
Hepatitis B Vaccine Dose Schedule: How Many Injections Do You Need?
The standard course is three doses. The accelerated course is four doses and is designed for travellers who need protection quickly. Both schedules are available at Doctor Bangkok on a walk-in basis.
| Standard Schedule (3 doses) | Accelerated Schedule (4 doses) | |
|---|---|---|
| Dose 1 | Day 0 (first visit) | Day 0 (first visit) |
| Dose 2 | 1 month after dose 1 | Day 7 |
| Dose 3 | 6 months after dose 1 | Day 21 |
| Dose 4 / Booster | Not required | 12 months after dose 1 |
| Full protection from | 2 weeks after dose 3 | 2 weeks after dose 3 (day 35) |
| Best for | Expats and long-stay residents | Travellers needing protection quickly |
Doctor Bangkok can administer all doses across your schedule, whether you are based in Bangkok or returning for subsequent doses. If you are uncertain which schedule suits your timeline, the physician will advise at the consultation.
What About a Hepatitis B Booster?
If you completed a 3-dose course more than ten years ago, your immunity may have declined. A hepatitis B surface antibody titer test measures your current antibody level. If it falls below the protective threshold of 10 mIU/mL, a single booster dose is recommended rather than repeating the full course. Doctor Bangkok can run the titer test and administer the booster on the same visit if results confirm it is needed.
Not sure which schedule you need?
WhatsApp us your situation and the physician will advise the right schedule at your consultation.
Hepatitis B Vaccine Side Effects
Common side effects (mild, 1 to 2 days)
Soreness or mild swelling at the injection site. Low-grade fatigue for 24 hours. Mild headache. All resolve without treatment. These are expected signs of an immune response.
Cannot cause hepatitis B infection
The vaccine does not contain live virus and cannot cause hepatitis B. Any mild symptoms after injection are your immune system building protection, not infection.
Safe during pregnancy
Recommended for unvaccinated pregnant women at risk. The physician reviews your obstetric history before administering and advises on timing within your pregnancy.
Anaphylaxis equipment on site
Serious allergic reactions are extremely rare. Full anaphylaxis management equipment is on site for every vaccination. All patients observed for 15 minutes as standard.
Had a Potential Hepatitis B Exposure?
If you have had a recent potential blood or sexual exposure to hepatitis B and are unvaccinated, seek medical assessment at Doctor Bangkok immediately. Post-exposure prophylaxis with hepatitis B immunoglobulin (HBIG) combined with the first vaccine dose can prevent infection if administered promptly after exposure. This is time-sensitive. Do not wait for a routine appointment.
⚠️ Post-exposure assessment is time-sensitive
Contact Doctor Bangkok immediately for an assessment. The sooner HBIG and the first vaccine dose are administered after exposure, the more effective the prevention.
Frequently Asked Questions
Do I need a hepatitis B vaccine if I was vaccinated as a child?+
You are likely still protected. Most people who completed a full hepatitis B vaccination course as a child retain immunity for life, though this is not universal. The most reliable way to confirm is a hepatitis B surface antibody titer blood test. Doctor Bangkok can run this on the same visit. If your immunity is confirmed above the protective threshold, no further doses are needed. If it has declined below 10 mIU/mL, a single booster dose restores protection.
How long does the hepatitis B vaccine take to work?+
Full protection develops approximately two weeks after the third dose of the standard or accelerated course. After dose one alone you have partial but not complete protection. After dose two you have significantly higher immunity. This is why completing the full course matters, and why the accelerated schedule exists for travellers who cannot wait six months for the standard timeline.
Can I get the hepatitis B vaccine if I have already been exposed?+
If you have had a recent potential blood or sexual exposure to hepatitis B and are unvaccinated, seek medical assessment at Doctor Bangkok immediately. Post-exposure prophylaxis with hepatitis B immunoglobulin (HBIG) combined with the first vaccine dose can prevent infection if administered promptly after exposure. This is time-sensitive. Do not wait for a routine appointment.
Is the hepatitis B vaccine the same as the hepatitis A vaccine?+
No. Hepatitis A and hepatitis B are different viruses requiring separate vaccines. Hepatitis A is primarily transmitted through contaminated food and water. Hepatitis B is transmitted through blood and sexual contact. A combined hepatitis A and B vaccine, known as Twinrix, is available and may be appropriate if you are unvaccinated against both. Ask the physician at your consultation whether the combined vaccine suits your situation.
How long does hepatitis B immunity last after the full course?+
For most people who complete the standard three-dose course and develop a protective antibody response, immunity is lifelong. Studies following vaccinated adults over several decades show sustained protection without the need for routine boosters. A titer test is the only reliable way to confirm your individual immunity level, particularly if your vaccination was more than ten years ago or if your records are incomplete.
Can I get the hepatitis B vaccine during pregnancy?+
Yes. The inactivated hepatitis B vaccine is considered safe during pregnancy and is recommended for pregnant women who are unvaccinated and at risk of exposure. Hepatitis B infection during pregnancy carries a high risk of transmission to the newborn, with a significant proportion of infants exposed at birth developing chronic infection. The physician at Doctor Bangkok will review your obstetric history before administering the vaccine.
Does Doctor Bangkok provide a vaccination certificate?+
Yes. A signed vaccination record is issued on the same day as your dose. This document is accepted by most airlines, employers, schools, and Thai government departments requiring proof of hepatitis B vaccination. If you need a specific format for a particular institution, inform the doctor at the consultation and we will accommodate this where possible.
