Hepatitis B Vaccination in Singapore
Hepatitis B is a viral infection that affects the liver and can lead to severe complications, such as cirrhosis, liver failure and liver cancer, if left untreated. The Hep B virus spreads through contact with infected blood, semen, or other bodily fluids.
Hepatitis B virus (HBV) is the most common hepatitis virus in Singapore, and 6% of the local population are Hep B carriers. It is estimated that between 25-50% of these carriers may die prematurely, either as a result of chronic liver inflammation, liver failure (cirrhosis) or liver cancer.
Why Do You Need the Hepatitis B Vaccine?
Hepatitis B is a contagious virus that transmits through blood, semen, or bodily fluids. Hep B infection can lead to serious complications like chronic liver disease, cirrhosis, or even liver cancer. Protecting yourself with the Hepatitis B vaccine is not just about your health—it’s about safeguarding your family and the communities you love.
As part of Singapore’s National Childhood Immunisation Schedule (NCIS) and National Adult Immunisation Schedule (NAIS), this vaccine plays a vital role in ensuring the well-being of everyone, from little ones to adults.
By choosing vaccination, you’re taking a powerful step to protect yourself and the people closest to you, helping create a healthier, stronger community for generations.
Why is Hepatitis B Screening Important?
Hepatitis B is often asymptomatic in its early stages, making regular screenings essential to prevent long-term liver damage.
1
Detect active infections before symptoms appear
2
Identify carriers who can unknowingly transmit the virus
3
Protect high-risk groups, such as pregnant women, healthcare professionals, and those with a family history of the disease.
Our screenings are designed to empower you to take control of your health, ensuring timely interventions for better outcomes.
Types of Hep B Vaccines in Singapore
Monovalent Hepatitis B Vaccines: These vaccines target only the Hepatitis B virus and are administered in three doses over six months (Months 0, 1 and 6). They are suitable for individuals of all ages, including newborns, children, and adults. Common brands include Engerix-B and Recombivax HB.
Combination Vaccines: For added convenience, combination vaccines protect against Hepatitis B and other diseases:
- Hexavalent Vaccines: These six-in-one vaccines protect against diphtheria, tetanus, pertussis (whooping cough), poliomyelitis, Haemophilus influenzae type b, and Hepatitis B. They are commonly administered to infants as part of the National Childhood Immunisation Schedule (NCIS). An example is Infanrix hexa.
- Twinrix: This vaccine offers protection against both Hepatitis A and Hepatitis B, making it suitable for those who require immunisation against both viruses. It’s recommended for those travelling to regions where these infections are prevalent.
Our doctor will help determine the best vaccine schedule for you. You may also check with us if you are eligible for subsidised vaccinations under Singapore’s National Adult Immunisation Schedule (NAIS).
How the Hepatitis B (HepB) Vaccine Works
At Prologue, we utilise Engerix-B as a powerful tool for protecting against Hepatitis B infection. It contains inactivated HBV surface antigens—proteins derived from the virus that are harmless yet strong enough to activate your immune system.
Introducing the Hep B vaccine into your body stimulates an immune response, prompting your system to produce antibodies that target the Hepatitis B virus. These antibodies act as vigilant defenders, ready to neutralise or destroy the virus if it ever enters your body.
How Engerix-B helps:
- Prevents HBV infection, reducing the risk of liver damage and cancer.
- Triggers immune response for long-term protection.
- Given in 3 doses over 6 months for lasting immunity.
- Recommended for newborns, healthcare workers, and at-risk individuals.
By creating this long-lasting immunity, the Hepatitis B vaccine (Engerix-B) provides enduring protection, helping you safeguard your liver health and overall well-being.
