    Pneumococcal Vaccine: What You Need to Know


    6. What if there is a moderate or severe reaction?

    What should I look for?

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

    Serious allergic reactions are extremely rare with any vaccine. If one were to occur, it would most likely be within a few minutes to a few hours after the shot. Signs can include:

    - difficulty breathing

    - hoarseness or wheezing

    - hives

    - paleness

    - weakness

    - a fast heart beat

    - dizziness

    - 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 health care provider to file a Vaccine Adverse Event Reporting

    System (VAERS) form. Or you can file this report through the VAERS web site at, or by calling 1-800-822-7967.

    7. The Vaccine Injury Compensation Program

    In the rare event that you or your child has a serious reaction to a vaccine, a federal program has been created to help pay for the care of those who have been harmed.

    For details about the National Vaccine Injury Compensation Program, call 1-800-338-2382 or visit the program's website at

    8. How can I learn more?

    • Ask your provider. They can give you the vaccine package insert or suggest other sources of information.
    • Call your local or state health department.
    • Contact the Centers for Disease Control and Prevention
