The Polio Vaccine: Health 101

Are there any side effects from the polio vaccine?

Contracting polio is far more dangerous than any side effects from the vaccine. Though allergic reactions are possible, the polio vaccine generally only causes mild side effects, like redness, swelling, or warmth near the injection site.

As with any vaccine, severe allergic reactions are rare, but possible. If you notice your child having difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, dizziness, or a rapid heartbeat shortly after he receives a shot, call your doctor right away.
