The polio vaccine offers protection against polio infection. Polio is a virus found in the nose and throat. It's spread by coughing, sneezing and sharing drink bottles. It infects the bowel and can attack the nervous system. In severe cases it may cause paralysis and even death.
Polio has disappeared from Aotearoa New Zealand and most parts of the world as a result of immunisation. However, there's still a risk that polio could enter New Zealand from overseas.

Polio vaccine works by making your immune system produce special cells called antibodies that will attack and kill the polio virus when it enters your body. This means that if you get infected, these protective antibodies are already in your bloodstream to quickly fight off the germs.
Being vaccinated causes your body to produce antibodies against the polio virus. This means your body can respond faster and more effectively to prevent an infection. It does this because by first coming across a non-infectious version of the virus in the vaccine, it learns to recognise it. When it comes across it again, your body can react much faster and in a more effective way.

Key points about the polio vaccine
- The polio vaccine protects against polio infection.
- The polio vaccine is also called Infanrix-hexa®, Infanrix-IPV® or IPOL®.
- Find out about the vaccine and possible side effects.
In Aotearoa New Zealand there are 3 polio-containing vaccines: Infanrix-hexa®, Infanrix-IPV® and IPOL®.
As part of the New Zealand childhood immunisation schedule, polio vaccine is offered free to:
- babies at 6 weeks, 3 months and 5 months as Infanrix-hexa®
- children at 4 years as Infanrix-IPV®.

Individuals who haven't been immunised against polio, or have had incomplete immunisation (missed some doses), or have a weakened immune system and are at risk of getting polio, can be given a course of 3 doses of inactivated polio vaccine (IPOL®), 4 to 8 weeks apart.
Pregnancy
Immunisation against polio isn't recommended in the first or second trimester of pregnancy unless you're travelling to a polio-affected area. If a previously unvaccinated pregnant woman is travelling to a country where polio is occurring, 2 doses should be administered 4 weeks apart prior to departure. If departure can't be delayed to allow a 4-week gap, give 2 doses at the maximum possible interval, though protection can't be guaranteed. If the available interval is less than 2 weeks, a single dose is recommended, with further doses given on arrival where possible.
Travel
If you're planning to travel to countries with a risk of polio infection, ensure that you're fully immunised against polio. If more than 10 years have passed since the last dose, a booster dose is recommended.
Infanrix–hexa® and Infanrix–IPV® are given intramuscularly (injected into the muscle) in the upper arm or thigh.
IPOL® is given by subcutaneous injection (under the skin).
Like all medicines, vaccines can cause side effects, although not everyone gets them.
