Hepatitis B Vaccine Singapore
Hepatitis B Vaccine in Singapore

What Is Hepatitis B?
Hepatitis B is caused by the hepatitis B virus (HBV) and can result in both acute and chronic liver disease, including cirrhosis and liver cancer. While some individuals can naturally clear the virus from their system, others develop chronic hepatitis B, which may persist for years or a lifetime, often requiring ongoing antiviral medication to manage the condition.
What Is the Hepatitis B Vaccine?


The hepatitis B vaccine is an immunisation designed to protect against the hepatitis B infection, which can cause serious liver complications. It stimulates the immune system to produce antibodies for long-term protection. It is recommended for infants, children, and adults at higher risk of infection, including healthcare workers and travellers to regions with high Hepatitis B prevalence.


How Is Hepatitis B Transmitted?
Hepatitis B is transmitted through contact with infected bodily fluids like blood, semen, and vaginal fluids. It can spread via unprotected sex, sharing needles, or from mother to baby during childbirth. Healthcare workers are also at risk from exposure to contaminated needles. It is not spread through casual contact such as hugging, shaking hands or sharing food and drinks.
Hepatitis B Symptoms
Hepatitis B symptoms can vary widely, with some individuals showing no signs and others developing symptoms of liver damage. Common symptoms include:
- Fatigue
- Jaundice (yellowing of the skin and eyes)
- Dark urine
- Pale stools
- Abdominal pain
- Nausea and vomiting
In chronic cases, the disease may progress silently for years, potentially leading to severe complications like liver cirrhosis, liver failure, or liver cancer, which may only become evident after significant liver damage.
How Does the Hepatitis B Vaccine Work?
The hepatitis B vaccine introduces a harmless component of the virus, prompting the immune system to produce protective antibodies. These antibodies help the body recognize and fight the virus if exposed, preventing infection. The vaccine is highly effective and provides long-term protection, with booster doses rarely needed.
When Is the Hepatitis B Vaccine Given?
In line with Singapore's National Childhood Immunisation Schedule (NCIS), it
is advised that all children receive three doses of the hepatitis B vaccine at specific intervals. The
first dose is administered at birth, and the series is usually completed by six months of age.
For adults, the Singapore National Adult Immunisation Schedule (NAIS)
recommends that individuals aged 18 and older who have not been previously vaccinated, or lack proof of
prior infection or immunity, receive three doses of the vaccine.
How Is the Hepatitis B Vaccine Administered?
The hepatitis B vaccine is usually given as an injection, either into a muscle (commonly in the arm) or just beneath the skin. It can be administered as a standalone vaccine or combined with other vaccines, such as the hepatitis A and B combination, providing protection against both viruses.
Hepatitis B Vaccine Dose & Schedule
The recommended dosage for the hepatitis B vaccine (Engerix-B®) is as follows:
Age Group | Vaccine Dosage & Schedule |
---|---|
Individuals aged 18 and above who are unvaccinated or were not previously infected |
3 doses. Second dose 1 month after the first dose. Third dose 6 months after the first dose. |
How Long Does the Hepatitis B Vaccine Last?
Over 90% of adults under 40 years old develop protective antibodies after the full vaccine series. By age 60, this drops to 75%. Despite this, the vaccine generally provides long-term protection, with boosters rarely needed.
What Precautions Should I Take Before a Hepatitis B Vaccination?
Before getting the hepatitis B vaccine, it is essential to inform your doctor if you:
- You are feeling unwell or have a fever.
- You are allergic to the vaccine or any of its ingredients.
- You are pregnant, planning to become pregnant, or breastfeeding.
- You have a weakened immune system, such as undergoing chemotherapy.
- You have a history of bleeding disorders.
- You are taking any medications.
Hepatitis B Vaccine Side Effects
Some people may experience minor side effects such as dizziness, pain or redness at the injection site, and headaches. These reactions are usually mild and temporary, but you should seek medical advice if they persist or worsen.
Uncommon but Severe Reactions to Look Out for After Your Vaccination
In rare cases, vaccinations may trigger severe allergic reactions, such as swelling of the face or eyes,
breathing difficulties, or widespread itchy rashes. Should any of these symptoms occur, immediate
medical attention is required.
