The polio vaccine is given to protect people from getting all three strains of the polio virus. The vaccine is given as a shot (injection).
Polio (poliomyelitis) is a virus that damages nerves that control muscles, resulting in muscle weakness. In a severe case, a person can lose the ability to move both arms and legs (paralysis) and to breathe without help.
In the early 1900s, thousands of people were paralyzed or died from polio. Today polio immunization programs have made the disease very rare in Canada, the United States, Europe, the Mediterranean, Japan, Australia, and New Zealand. Outbreaks are common in other parts of the world.
For babies and children
A total of four shots are given at 2 months, 4 months, 6 months, and between 4 to 6 years of age. The polio vaccine may be combined with other vaccines so children only have to receive one shot (known as the 4-in-1, 5-in-1, or 6-in-1 shots).
A booster dose of the polio vaccination is not needed for adults (even those who were not immunized as children) unless they:footnote 1
The series given to children provides lifelong protection.
Most people who get the vaccine do not have any problems. But there may be soreness or tenderness where the shot was given. There have been no reports of any serious reactions with the vaccine used today. footnote 2
Even though serious allergic reactions are rare with these medicines, call your doctor or local health unit right away if you or your child has trouble breathing, a high fever, or anything unusual after having the shot.
A child who has had a severe allergic reaction to a previous dose of polio vaccine should not get another dose of this vaccine. Tell your doctor or nurse if your child has had a severe reaction to any vaccine or has severe allergies.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
Only the inactivated polio vaccine shot (injection) is used in Canada today. An oral vaccine was once used but is no longer because it had rare but serious risk of causing polio.
