Hib Vaccine


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 through coughing, sneezing, or sharing utensils. The Hib vaccine is often combined with other vaccines. In infants and children, the vaccine is given in the thigh. In older children and adults, it is given in the upper arm.

Who should get the Hib vaccine?

  • Infants and children 2 months to 4 years receive 4 doses. 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
    • The final dose at 12 to 15 months
  • Adults and children 5 years or older with a weak immune system who have not received the vaccine may need 1 dose. Anyone who received a stem cell transplant should receive a 3-dose series starting 6 months after the transplant.
  • Adults and children at high risk who have any of the following conditions may need 1 dose if not already vaccinated:
    • HIV or AIDS
    • Leukemia
    • Sickle cell disease
    • Surgery to remove the spleen

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

Ask your child's healthcare provider what to do if a dose is missed.

Who should not get the Hib vaccine?

The Hib vaccine is usually not given to people 5 years or older. This is because most people are protected against infection from an earlier exposure to the Hib bacteria. Do not get the Hib vaccine if you had an allergic reaction to the vaccine in the past. Do not get the vaccine if you are allergic to latex, gelatin, thimerosal (mercury), or any other part of the vaccine. Do not get the vaccine if you are sick or have a fever. Wait until you recover from your illness.
