Polio is a serious illness. Polio infection may cause mild symptoms or very severe illness.
Some people may have no symptoms or mild flu like illness, while others may have serious symptoms such as meningitis (where the lining of the brain becomes inflamed) or paralysis(where they loose the use of their muscles) Of the people who get polio
- 1 in 100 will become paralysed.
- 1 in 20 patients who become paralysed will die.
- 1 in 2 of those with paralysis who survive will be permanently paralysed.
What are the symptoms of polio?

Symptoms include;
- Headache
- Feeling generally unwell, with a temperature.
- Vomiting
- Stiffness of the neck and back, which may lead to paralysis (loss of the use of muscles) if the infection reaches the central nervous system.
- In the worst cases the muscles used for breathing are paralysed, which can be fatal.
How can polio be prevented?
Back to Top
The most important way to prevent polio is by immunisation with Inactivated (Killed) Polio Vaccine (IPV). Currently in Ireland, the vaccine for polio is usually given as part of the “5-in–1” vaccine (DTAP-HiB-IPV). This vaccine protects against pertussis, diphtheria, tetanus, Haemophilus influenzae type b, and polio. Three doses of the “5-in-1” vaccine are usually given at two, four and six months of age. A fourth dose is recommended at 4-5 years.
If your child requires vaccination, or you are unsure of your child’s vaccination status, contact your GP for advice.
What are the types of polio vaccine?
Back to Top
There are two types of polio vaccine. Inactivated (killed) polio vaccine (IPV) which is given by injection, and live oral polio vaccine (OVP) which is a liquid and swallowed sometimes on a sugar lump.
In Ireland Inactivated (Killed) polio vaccine (IPV) is recommended. While the other type of vaccine, live oral polio vaccine (OPV) is an excellent vaccine on very rare occasions it can actually cause polio. The risk of getting polio is very low once in every 2.4 million doses. The experts have decided that the use of the Inactivated (killed) polio vaccine is safer.
Is Polio Vaccine Safe?
Back to Top
Yes Inactivated (Killed) polio vaccine (IPV) is a very safe vaccine.
No serious side effects have been recorded for inactivated polio vaccine which has been used for over 40 years. There may be a little redness or soreness where the injection was given .
In the past there have been scare stories regarding oral polio vaccine (OPV). The experts have decided that the use of the Inactivated (killed) polio vaccine (IPV) is safer than oral polio vaccine (OPV).
