What should I look for?

Look for any unusual condition, such as a serious allergic reaction, high fever, or unusual behavior.

If a serious allergic reaction occurred, it would happen within a few minutes to a few hours after the shot. Signs of a serious allergic reaction can include difficulty breathing, weakness, hoarseness or wheezing, a fast heart beat, hives, dizziness, paleness, or swelling of the throat

What should I do?

• Call a doctor, or get the person to a doctor right away. Tell your doctor what happened, the date and time it happened, and when the vaccination was given.
  
• Ask your doctor, nurse, or health department to file a Vaccine Adverse Event Reporting System (VAERS) form, or call the VAERS toll-free number yourself at 1-800-822-7967.
