What Is Hepatitis B?

Hepatitis B is a viral infection affecting the liver. It is caused by the hepatitis B virus (HBV) and can lead to either a short-term infection or a long-term condition known as chronic hepatitis B.

Chronic infection can increase the risk of serious liver problems, including cirrhosis and liver cancer.

Many people with hepatitis B do not experience noticeable symptoms, making prevention, screening and vaccination important.

How Does Hepatitis B Spread?

Hepatitis B can spread through contact with infected blood and certain body fluids. Common routes include:

• Sexual contact with someone who has hepatitis B.
• Sharing needles or other equipment contaminated with blood.
• Exposure to contaminated sharp instruments.
• Transmission from a parent to a baby during birth.
• Occupational exposure to infected blood.

Hepatitis B does not spread through ordinary social contact such as hugging, coughing or sharing food.

Who Should Get the Hepatitis B Vaccine?

Hepatitis B vaccination is recommended for many people who have not previously completed an appropriate vaccine series.

Vaccination may be particularly relevant for:

• Adults without confirmed vaccination history: People who are unsure whether they received a complete hepatitis B vaccine course.
• Healthcare professionals: Doctors, nurses, laboratory workers and others exposed to blood or bodily fluids.
• International travellers: People visiting or living in regions where hepatitis B is more common.
• Sexually active adults: Particularly people with increased risk of exposure to HBV.
• Household contacts: People living with someone who has hepatitis B.
• People with certain medical conditions: Including individuals who may be at increased risk of complications or exposure.

Recommendations depend on age, vaccination history, medical conditions and individual risk. A clinician can advise whether vaccination or additional blood testing is appropriate.

Hepatitis B Vaccine Schedule: How Many Doses Are Needed?

The Engerix-B vaccine commonly follows a three-dose schedule for adults.

The schedule may differ for children and people with certain medical conditions. Your healthcare provider will determine the appropriate dose and timing.

What Happens If You Miss a Hepatitis B Vaccine Dose?

In most cases, a delayed dose does not mean you need to restart the entire vaccination series.

Your healthcare provider can review the previous doses and advise when to continue the remaining injections.

Do You Need a Hepatitis B Blood Test Before Vaccination?

Some people may benefit from a hepatitis B blood test before vaccination, particularly if their previous infection or vaccination history is uncertain.

Common hepatitis B blood markers include:

• HBsAg: Helps identify a current hepatitis B infection.
• Anti-HBs: Helps assess protective antibodies, including immunity from vaccination.
• Total Anti-HBc: Helps identify previous or current exposure to hepatitis B infection.

These tests are often considered together to understand a person’s hepatitis B status.

Not everyone needs antibody testing before or after vaccination. Testing should not unnecessarily delay vaccination when it is indicated.

A clinician can help decide which blood tests, if any, are appropriate.

Is the Hepatitis B Vaccine Safe?

Hepatitis B vaccines have an established safety record and are widely used internationally.

Common temporary side effects can include:

• Soreness or redness at the injection site.
• Mild headache.
• Fatigue.
• Occasional mild fever.

Severe allergic reactions are rare. People with a history of a serious allergic reaction to a previous vaccine dose or any vaccine component should inform their clinician before vaccination.

Pregnant patients and people with significant medical conditions should discuss vaccine selection and timing with their healthcare provider.

Can You Receive the Hepatitis B Vaccine After Exposure?

If you believe you have recently been exposed to hepatitis B through blood or sexual contact, seek medical assessment promptly.

Depending on your vaccination history and the type of exposure, a clinician may recommend hepatitis B vaccination, hepatitis B immune globulin (HBIG), testing or a combination of measures.

Do not wait for a routine vaccination appointment after a suspected high-risk exposure.

Hepatitis B Vaccination for Expats and Travellers in Bangkok

Bangkok has a large international community, including expatriates, students, business travellers and long-term residents.

Hepatitis B vaccination may be especially relevant for people who:

• Have moved to Thailand and are unsure of their vaccination history.
• Travel frequently across Asia or other regions with a higher hepatitis B burden.
• Work in healthcare or other occupations involving possible blood exposure.
• Want to complete an unfinished vaccination series.

If you have limited time before travelling, a doctor can help you plan an appropriate vaccination schedule.
