The Haemophilus influenzae type B vaccine (commonly called Hib vaccine) is used to prevent infections caused by the bacteria (bug) Haemophilus influenzae type B. Haemophilus influenzae is the name of a group of bacteria that can cause mild to very serious illness. The most common strain is type B (also called Hib). Hib can cause a range of infections from mild ear infections to serious bloodstream infections or meningitis. Find out more about Haemophilus influenzae.

Vaccination is the best method for preventing infection and reducing the seriousness of illness if you become infected. Being vaccinated with 2 doses against Hib will protect 90–100% of children up to the age of 6 from catching, or being seriously unwell from the disease.
The vaccine works by causing your body to produce its own protection (antibodies) against the bacteria.
You can't get Hib disease from the vaccine, as it doesn't contain live, active bacteria.
Hib vaccine is part of the New Zealand Immunisation Schedule and is offered free to babies. It's also offered free to children and adults with a weakened immune system, or those who have had their spleen removed, who are at high risk of Hib disease.
In Aotearoa New Zealand there are 3 different brands of Hib vaccine – Infanrix-hexa®, Hiberix® and Act–HIB®.

Hib disease is an infection caused by the bacteria Haemophilus influenzae. These bacteria live in the nose and throat of most healthy people without causing illness. They're easily passed from person to person by coughing, sneezing and close contact.
Hib disease can cause a range of infections from mild ear infections to serious bloodstream infections or meningitis.
Not everyone who catches Hib bacteria gets sick from it, but those most at risk of serious disease are:
- children under 5 years of age
- infants attending day care
- people living in a large or crowded household
- people living with preschool or school-aged siblings.

Vaccination is the best method for preventing Hib disease and reducing the seriousness of illness if you become infected. Vaccination against Hib is 90–100% effective in decreasing the risk of disease for children until they're 6 years of age.

The Hib vaccine is free as part of the New Zealand Immunisation Schedule for babies at 6 weeks, 3 months and 5 months (Infanrix–hexa). A booster dose of Hiberix or Act-HIB is given at 15 months of age. Children aren't fully protected until they’ve had all 4 doses. If your child misses these dates, they can have catch-up Hib vaccines. Talk to your healthcare provider about this. Read more about childhood immunisation.

Some children, teenagers and adults with weakened immune systems who are at risk of Hib disease may be eligible for revaccination. Check with your healthcare provider about their eligibility.

The Hib vaccine is given by injection into a muscle, eg, the muscle on your mid thigh or upper arm.

Like all medicines, the Hib vaccine can cause side effects, although not everyone gets them.
