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.

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.

Seek care immediately if:

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

Call your child's doctor if:

  • 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.

Who should get the Hib vaccine:

  • Infants and children 2 months to 4 years receive 2 to 3 regular doses and a booster dose. The first dose can be given as early as 6 weeks of age. Hib shots are usually given at the following times:
    • 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 5 years or older with a weak immune system who have not received the vaccine may need 1 dose. A child who received a stem cell transplant should receive a 3-dose series starting 6 to 12 months after the transplant.
  • Children at high risk who have any of the following conditions may need 1 or more doses if not already vaccinated:
    • HIV or AIDS
    • Sickle cell disease
    • Surgery to remove the spleen
    • Chemotherapy or radiation
    • Hematopoietic stem cell transplant (HSCT)
    • Immunoglobulin deficiency, early component complement deficiency

If your child misses a dose of the Hib vaccine

, ask his or her doctor when to get a catch-up dose.

Who should not get the Hib vaccine:

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 healthcare provider 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.

Apply a warm compress

to the injection area as directed to decrease pain and swelling.
