Pneumococcal Conjugate Vaccine
What You Need to Know

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
  • weakness
  • hives
  • hoarseness or wheezing
  • fast heart beat
  • pallor
  • swelling of the throat
  • 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 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.
