- Polio is a disease caused by infection with the polio virus.
- 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.
- Polio can be spread by contact with the bowel movements (stool) 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).
The polio vaccine is combined with other vaccines so that you or your child can get protection against several diseases with fewer shots. There are several different combination vaccines used to prevent polio in infants, children, adolescents and adults.
- 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 a 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. The booster dose strengthens or boosts the immune system to give better protection against these diseases.
- 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 polio virus (for example, through work or travel).
- People who have not been immunized and may be exposed to the polio virus 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.
