Childhood vaccine
6-in-1 Vaccine
The 6-in-1 vaccine protects babies against six serious infections in a single injection, given at 8, 12 and 16 weeks of age.
What it protects against
It protects against diphtheria, tetanus, whooping cough (pertussis), polio, Haemophilus influenzae type b (Hib) and hepatitis B — six infections that can cause serious illness in babies.
Who it's for
All babies in the UK, given as three doses at 8, 12 and 16 weeks of age as part of the routine childhood schedule.
How it works
It contains inactivated components of the germs, which prompt the baby’s immune system to make protective antibodies without causing the diseases themselves.
Safety
Safety and side effects
It is very safe and well studied. Common effects are mild — redness or swelling at the injection site, a raised temperature, irritability or being unsettled — and pass within a day or two.

Answers
6-in-1 Vaccine: frequently asked questions
Why give six vaccines in one injection?
Combining them means fewer injections and appointments while protecting against all six diseases early, when babies are most vulnerable. Combination vaccines are thoroughly tested and just as safe and effective.
What if my baby misses a dose?
It is best to keep to the schedule, but missed doses can be caught up. Contact your GP surgery to arrange the remaining doses as soon as possible.
