Immunization protects you from disease.Get protected, get immunized.
The Hib vaccine protects against Haemophilus influenzae type b bacteria.
This vaccine is given to children under age 5 years who have been immunized for diphtheria, tetanus, pertussis, and polio and only need the Hib vaccine.
Older children and adults may also get this vaccine if they have a high risk of severe Hib disease because of health problems. This may include those with no spleen, a weak immune system, or those who have a cochlear implant.
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.
DTaP-IPV-Hib protects against diphtheria, tetanus, pertussis (whooping cough), polio and Hib. This vaccine is given to children born before March 1, 2018, who are under age 7 years as part of their primary series. Children also get this vaccine as a booster dose when they are age 18 months.
DTaP-IPV-Hib-HB is a vaccine that babies get if they are born on or after March 1, 2018. It protects against all of the same diseases as DTaP-IPV-Hib as well as hepatitis B.
After the primary series and a booster dose, protection is over 95%. It may be less if your immune system is weak.
You can get the vaccine at a public health office in your area.
There can be side effects from the Hib vaccine, but they tend to be mild and go away in a few days. Side effects may include:
It’s important to stay at the clinic for 15 minutes after your vaccine. Some people may have a rare but serious allergic reaction called anaphylaxis. If anaphylaxis happens, you will get medicine to treat the symptoms.
It’s rare to have a serious side effect. Call Health Link at 811 to report any serious or unusual side effects.
You may not be able to get the vaccine if you:
Check with your doctor or a public health nurse before you get the vaccine.
You can still have the vaccine if you have a mild illness, such as a cold or fever. Always tell your healthcare provider if you have allergies or if you have had a side effect from a vaccine in the past.
