Information

Polio vaccine

The inactivated polio vaccine (IPV) is mostly given as a booster dose to adults who received the polio vaccine in childhood and are at increased risk of exposure to the polio virus. In young children, immunization against polio is combined with other vaccines.

Disease it protects against

The polio vaccine protects against:
 
  • Polio
Polio is a serious infection that can result in paralysis of arms or legs and even death. There is no cure for polio. Learn more about polio.
Fact

Did you know?

Before the vaccine, thousands of Canadians were paralyzed or died from polio. 

Who should get the vaccine

Age Schedule
Infants & young children
School-age children & teens
  • Those who never received the recommended doses of vaccine should get this vaccine.
Adults
  • Those who received the polio vaccine in childhood and are at increased risk of exposure to polio viruses. 
 

How well it works

When people get all the recommended doses, the protection is almost 100% for polio.
 
When you get immunized, you help protect others as well. People who are immunized are much less likely to catch a preventable disease and spread it to others. 
Fact

Did you know?

Thanks to vaccination, Canada has been polio-free for more than 20 years.  However, until polio is eliminated globally, immunization is the best protection.

Safety

Vaccines are very safe and getting the vaccine is much safer than getting polio. Vaccine safety is a top priority in Canada. Every vaccine must be shown to be safe and effective before it is approved for use in Canada. After approval, the safety of vaccines is continuously monitored. Learn more about vaccine safety.
 

Side effects

Often, vaccines cause no side effects, but sometimes they do. When side effects happen after the polio vaccine, they are generally minor and usually last 1 to 2 days. Serious side effects are very rare. 
 
Side effects of the polio vaccine can include:
 
  • Redness, swelling, and soreness where the vaccine was given
  • Fever 
It is important to stay in the clinic for 15 minutes after getting any vaccine because there is an extremely rare chance of a life-threatening allergic reaction called anaphylaxis. If anaphylaxis happens, you will be given medicine to treat the symptoms.
 
Let your immunization provider/clinic or health care provider know if you or your child have any serious or unexpected side effects after immunization.
 
 

How to manage side effects

Who should not get the vaccine

Speak to your health care provider if you or your child has had a life-threatening reaction to a previous dose of polio vaccine or to any component of the vaccine, including neomycin, streptomycin or polmyxin B. 
 
There is no need to delay getting immunized because of a cold or other mild illness. However, if you have concerns, speak to your health care provider.
 

Polio quick facts

What is polio?
 
Polio is a disease caused by infection with the polio virus. Due to immunization, polio has been eliminated in most parts of the world. In 1994, Canada was certified as a “polio-free” country. However, until polio is eliminated globally, immunization is the best protection.
 
How does it spread?
 
Polio can be spread by contact with the stool of an infected person. This can happen by eating food or drinking water contaminated with stool.
 
What are the symptoms and risks?
 
While most polio infections show no symptoms, others can result in paralysis of arms or legs and even death. Paralysis occurs in about 1 in 200 people infected with the polio virus.
