The legal framework
Singapore introduced universal infant hepatitis B vaccination in 1987, among the first countries in the region to do so, and prevalence in younger cohorts has fallen dramatically as a result. Antenatal screening is universal, and chronic carriers are monitored through specialist services.
Singapore introduced universal infant hepatitis B vaccination in 1987, among the earliest in the world, with a birth dose for every newborn, and chronic infection among younger cohorts has fallen to very low levels. Antenatal screening is universal, and vaccination is part of the national childhood immunisation schedule, with costs payable from MediSave.
Key points
| Infant vaccination | Universal since 1987, with a birth dose |
|---|---|
| Older cohorts | People born before the programme have markedly higher prevalence |
| Antenatal screening | Universal |
| Babies of carriers | Vaccine and immunoglobulin at birth |
| Testing | Available at polyclinics and private practice |
| Treatment | Subsidised at public institutions |
| Monitoring | Regular surveillance for liver cancer in chronic carriers |
In practice
- If you were born before 1987, ask for testing: your cohort was not routinely vaccinated.
- Chronic carriers need regular ultrasound surveillance, not just blood tests.
- Household contacts should be tested and vaccinated.
- Ask for the full serology in one request.
Cost and coverage
Testing and treatment are subsidised at public institutions.
Where to go
- Polyclinics and hospital gastroenterology departments.
- Health Promotion Board for vaccination information.
- Specialist liver clinics for monitoring.
Worth knowing
Chronic carriers need liver cancer surveillance by ultrasound, typically twice a year. Blood tests alone are not sufficient, and this is often the part that gets dropped.
Frequently asked questions
Is vaccination compulsory in Singapore?
Hepatitis B is part of the national childhood immunisation schedule, which is strongly enforced through school entry requirements, and the birth dose is given as a matter of routine. Costs for scheduled vaccines can be met from MediSave for citizens.
Why does the birth dose matter so much?
Because transmission from mother to baby at birth is the route most likely to produce a lifelong chronic infection — an infant infected at birth has a very high chance of never clearing the virus, whereas an adult usually does. A vaccine dose within twenty-four hours of birth, with immunoglobulin where the mother is positive, prevents this in the great majority of cases.
