Polio is a viral infection that can result in permanent paralysis.
The inactivated poliovirus vaccine (IPV) is usually given at ages 2 months, 4 months, 6-18 months, and 4-6 years.
Though the oral poliovirus vaccine (OPV) is still used in many parts of the world, it has not been used in the United States since 2000. Using IPV eliminates the small risk of developing polio after receiving the live oral polio vaccine.
Why the Vaccine Is Recommended
The vaccine offers protection against polio, which can cause paralysis and death.
Side effects include fever and redness or soreness at the site of injection. There is a very small chance of an allergic reaction with any vaccine.
When to Delay or Avoid Immunization
The vaccine is not recommended if your child:
- has a severe allergy to neomycin, streptomycin, or polymyxin B
- had a severe allergic reaction to a previous IPV shot
Caring for Your Child After Immunization
IPV may cause mild fever, and soreness and redness at the site of the injection for several days. Depending on your child's age, pain and fever may be treated with acetaminophen or ibuprofen. Check with your doctor to see if you can give either medication, and to find out the appropriate dose.
When to Call the Doctor
- Call if you aren't sure whether the vaccine should be postponed or avoided.
- Call if moderate or severe adverse reactions occur after the immunization.
