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
