Hib Vaccine

WHAT YOU NEED TO KNOW:

What is the Hib vaccine?

The Hib vaccine is an injection given to help prevent a Haemophilus influenzae type b (Hib) infection. Hib is a common bacterial infection that spreads when a person coughs, sneezes, or shares utensils. The Hib vaccine is often combined with other vaccines.

Who should get the Hib vaccine?

  • Infants and children 2 months to 4 years:
    • The first dose at 2 months
    • The second dose at 4 months
    • The third dose at 6 months (if needed)
    • A booster dose at 12 to 15 months


  • Children at high risk who have any of the following conditions may need 1 or more doses if not already vaccinated:
    • Weakened immune system due to HIV, chemo, or radiation
    • Stem cell transplant
    • Sickle cell disease
    • Surgery to remove the spleen
    • Immunoglobulin deficiency, early component complement deficiency

What should I do if my child misses a dose of the Hib vaccine?

Talk to your child's doctor about when to bring your child in for a catch-up dose.

Who should not get the Hib vaccine or should wait to get it?

Your child should not get the Hib vaccine if he or she had an allergic reaction to the vaccine. Your child should not get the vaccine if he or she is allergic to latex, gelatin, thimerosal (mercury), or any other part of the vaccine. Tell your child's doctor about all of your child's allergies. If your child is sick or has a fever, wait until he or she recovers before getting the vaccine.

Call your local emergency number (911 in the US) if:

  • Your child's mouth and throat are swollen.
  • Your child is wheezing or having trouble breathing.
  • Your child has chest pain or his or her heart is beating faster than usual.
  • Your child feels like he or she is going to faint.

When should I seek immediate care?

  • Your child's face is red or swollen.
  • Your child has hives that spread over his or her body.

When should I call my child's doctor?

  • Your child feels weak or dizzy.
  • Your child has increased pain, redness, or swelling around the area where the shot was given.
  • You have questions or concerns about the Hib vaccine.
