The legal framework
The United Kingdom was a late adopter of universal infant hepatitis B vaccination, introducing it in the routine schedule in 2017. Before that, vaccination was offered selectively, which left large parts of the adult population unprotected. Antenatal screening has long been universal, and treatment is free on the health service.
The UK added hepatitis B to the routine infant schedule in 2017, as part of the six-in-one vaccine, so anyone born before that year was not routinely vaccinated unless they were in a risk group. Screening in pregnancy is universal, and babies born to positive mothers receive a birth dose and a tailored schedule with follow-up testing at one year.
Key points
| Infant vaccination | Universal since 2017, in the combined six-in-one vaccine |
|---|---|
| Before 2017 | Selective vaccination only, leaving most adults unvaccinated |
| Antenatal screening | Universal and long established |
| Babies of carriers | Vaccine from birth, with immunoglobulin where indicated |
| Testing | Free at sexual health clinics and through GP practices |
| Treatment | Free on the health service |
| Higher prevalence groups | People born in countries of higher endemicity |
In practice
- If you were born before 2017, assume you were not vaccinated unless you know otherwise.
- Ask for the full serology — surface antigen, core antibody and surface antibody — not a single marker.
- If you were born in a country of higher prevalence, ask for testing even without symptoms.
- After an exposure, seek vaccine and immunoglobulin within 48 hours.
Cost and coverage
Testing, vaccination for those at risk, and treatment are free on the health service.
Where to go
- Sexual health clinics for free testing and vaccination.
- GP practices and occupational health services.
- British Liver Trust for information and support.
Worth knowing
Most adults in the United Kingdom are not vaccinated, because universal infant vaccination started only in 2017. If you are at any risk, do not assume childhood protection.
Frequently asked questions
Was I vaccinated as a child in the UK?
Only if you were born in 2017 or later, when hepatitis B entered the routine infant schedule, or if you were in a defined risk group. Everyone else was not routinely vaccinated. A blood test settles it, and catch-up vaccination is free for those at higher risk.
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.
