Hepatitis A Vaccination in Singapore
Hepatitis A is a contagious viral infection caused by the Hepatitis A Virus (HAV), primarily affecting the liver. It is transmitted through ingesting food or water contaminated with faecal matter or direct contact with an infected person.
Hepatitis A can cause symptoms such as fatigue, stomach pain, nausea, and jaundice (yellowing of the skin and eyes). While most individuals recover without lasting liver damage, severe cases can lead to liver failure, particularly in individuals aged over 50 or with existing liver conditions.
How Does the Hepatitis A Vaccine Work?
The Hepatitis A vaccine introduces inactivated components of the virus, which do not cause disease but stimulate your immune system to produce protective antibodies. These antibodies thereafter act as a defence mechanism, neutralising the virus in the case of future exposure.
Why is Hepatitis A Screening and Vaccination Important?
Hepatitis A is highly contagious, and infected individuals can unknowingly transmit the virus even if they exhibit no symptoms.
Screening and vaccination play a vital role in:
- Preventing the spread of the virus within families.
- Reducing the risk of outbreaks in communities.
- Protecting high-risk groups, such as travellers to developing countries, children, and individuals with liver conditions.
How Is the Hepatitis A Vaccine Given?
The vaccine is typically administered as an injection into the muscle, either on its own, requiring two doses spaced 6–12 months apart, or with the Hepatitis B vaccine. Depending on age, two or three doses may be needed.
Our doctor will thoughtfully guide you in choosing the schedule that best supports your unique needs, ensuring you feel holistically cared for throughout your visit.
Who Should Receive the Hepatitis A Vaccine?
The vaccine is recommended for individuals who:
1
Are travelling to or living in developing countries where Hepatitis A is widespread.
2
Are at higher risk due to occupational exposure, lifestyle factors, or health conditions.
3
Those with close contact with infected persons.

- Infants and Children:
- The first dose is recommended between 12 and 23 months of age.
