Disease it protects from

Who should get this vaccine

Children under age 5 years who have been immunized for diphtheria, tetanus, pertussis, and polio and only need the Hib vaccine can get this vaccine.

Older children and adults may also get this vaccine if they have a high risk of severe Hib disease because of health problems. These may include those with no spleen, a weak immune system, or those who have a cochlear implant.

Who should not get this vaccine

You may not be able to get this vaccine if:

  • You have an allergy to any part of the vaccine.
  • You had a severe (serious) or unusual side effect after this vaccine or one like it.

If you have allergies or have had a side effect from this vaccine in the past, check with your doctor or a public health nurse before you get the vaccine.

Although you can get the vaccine if you have a mild illness, such as a cold or fever, you should stay home until you are feeling better to prevent spreading your illness to others.


The number of doses you need depends on your age and why you’re having the vaccine.

You usually get 3 doses (the primary series) of the Hib vaccine as a baby in a combined vaccine that protects against other diseases. This is followed by an extra (booster) dose at age 18 months.

If you have certain health problems, you may need more doses after age 5 years.
