What is a booster dose?
Immunity (protection) from some vaccines weakens with time. A "booster" dose is an added dose of vaccine given to strengthen or "boost" the immune system to provide better protection against disease.
What is the polio vaccine?
The polio vaccine protects against polio, a disease caused by infection with the poliovirus.
In young children, the polio vaccine is usually combined with other vaccines so that children can get protection against several diseases with fewer shots.
Who should get the polio vaccine?
The polio vaccine is recommended for all children. Some adults who are at increased risk of polio should also get the vaccine. There are many different vaccines used to prevent polio.
Diphtheria, Tetanus, Pertussis, Hepatitis B, Polio and Haemophilus influenzae type b (DTaP-HB-IPV-Hib) Vaccine
- This vaccine is given as a series of 3 doses to infants at 2, 4, and 6 months of age.
- This vaccine is given to infants as a booster dose at 18 months of age after completing a three-dose primary series of DTaP-HB-IPV-Hib.
- This vaccine is given as one dose to children 4-6 years of age. This is a booster dose for children who were immunized against diphtheria, tetanus, pertussis, and polio at a younger age.
- This vaccine is mostly given as a booster dose to adults who had a series of polio vaccine in childhood and are at increased risk of exposure to the poliovirus (for example, through work or travel).
- People who have not been immunized and may be exposed to the poliovirus through work or travel should also get the vaccine.
- A series of this vaccine can also be given to infants and children who have already received protection from diphtheria, tetanus, pertussis, and Hib in other vaccines.
What are the benefits of the vaccine?
The polio vaccine is the best way to protect against polio, a serious disease that sometimes causes death. When you or your child get vaccinated, you help protect others too.
What are the side effects?
Vaccines are very safe. It is much safer to get the vaccine than it is to get polio.
Many people have no side effects from these vaccines. For those that do, side effects are usually mild and last 1 to 2 days (see a list of common side effects for each vaccine below). Serious side effects are very rare.
It is important to stay in the clinic for 15 minutes after getting any vaccine because there is a very rare possibility, between one in 100,000 and one in a million, of a life-threatening allergic reaction called anaphylaxis. This may include hives, difficulty breathing, or swelling of the throat, tongue or lips. Should this reaction occur, your health care provider is prepared to treat it. Emergency treatment includes injection of epinephrine (adrenaline) and transfer by ambulance to the nearest emergency department. If symptoms develop after you leave the clinic, call 9-1-1 or the local emergency number.
It is important to always report serious or unexpected reactions to your immunizing health care provider.
Common side effects may include soreness, redness, and swelling where the vaccine was given. Some children may have a fever or experience crankiness, restlessness, vomiting, diarrhea, persistent crying, or a loss of appetite. These reactions are mild and usually last 1 to 2 days.

Some children may have a fever, or experience crankiness, drowsiness, loss of appetite, vomiting, and diarrhea. These reactions are mild and generally last 1 to 2 days. Large areas of redness and swelling may be present but these generally do not interfere with normal activity.

- Polio is a disease caused by infection with the poliovirus.
- 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 poliovirus.
- Polio can be spread by contact with the bowel movements (stool/poop) of an infected person. This can happen from eating food or drinking water contaminated with stool.
Extensive use of the polio vaccine has eliminated the disease in the western hemisphere. However, polio still exists in three countries (Pakistan, Afghanistan, and Nigeria). It takes only one traveler with polio to bring the disease into Canada, and if people aren't immunized, it could spread quickly here. To keep Canada polio-free, we need to keep vaccinating against it until the disease is completely eliminated world-wide.
