What if there is a moderate or severe reaction?
What should I look for? • Any unusual condition, such as a high fever, weakness, or behavior changes. Signs of a serious allergic reaction can include difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, a fast heart beat or dizziness. 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 provider to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS) form. Or you can file this report through the VAERS website at www.vaers.hhs.gov, or by calling 1-800-822-7967. • VAERS does not provide medical advice. • Reporting reactions helps experts learn about possible problems with vaccines.
