Hib vaccine can prevent
Haemophilus influenzae type b (Hib) disease.
Haemophilus influenzae type b can cause many different kinds of infections. These infections usually affect children under 5 years of age, but can also affect adults with certain medical conditions. Hib bacteria can cause mild illness, such as ear infections or bronchitis, or they can cause severe illness, such as infections of the bloodstream. Severe Hib infection, also called invasive Hib disease, requires treatment in a hospital and can sometimes result in death.
Before Hib vaccine, Hib disease was the leading cause of bacterial meningitis among children under 5 years old in the United States. Meningitis is an infection of the lining of the brain and spinal cord. It can lead to brain damage and deafness.
Hib infection can also cause:
Hib vaccine is usually given as 3 or 4 doses (depending on brand). Hib vaccine may be given as a stand-alone vaccine, or as part of a combination vaccine (a type of vaccine that combines more than one vaccine together into one shot).
Infants will usually get their first dose of Hib vaccine at 2 months of age, and will usually complete the series at 12-15 months of age.
Children between 12-15 months and 5 years of age who have not previously been completely vaccinated against Hib may need 1 or more doses of Hib vaccine.
Children over 5 years old and adults usually do not receive Hib vaccine, but it might be recommended for older children or adults with asplenia or sickle cell disease, before surgery to remove the spleen, or following a bone marrow transplant. Hib vaccine may also be recommended for people 5 to 18 years old with HIV.
Hib vaccine may be given at the same time as other vaccines.
Tell your vaccine provider if the person getting the vaccine:
In some cases, your health care provider may decide to postpone Hib vaccination to a future visit.
People with minor illnesses, such as a cold, may be vaccinated. People who are moderately or severely ill should usually wait until they recover before getting Hib vaccine.
Your health care provider can give you more information.
People sometimes faint after medical procedures, including vaccination. Tell your provider if you feel dizzy or have vision changes or ringing in the ears.
As with any medicine, there is a very remote chance of a vaccine causing a severe allergic reaction, other serious injury, or death.
An allergic reaction could occur after the vaccinated person leaves the clinic. If you see signs of a severe allergic reaction (hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness), call 9-1-1 and get the person to the nearest hospital.
For other signs that concern you, call your health care provider.
Adverse reactions should be reported to the Vaccine Adverse Event Reporting System (VAERS). Your health care provider will usually file this report, or you can do it yourself. Visit the VAERS website at www.vaers.hhs.gov at www.vaers.hhs.gov or call 1-800-822-7967.VAERS is only for reporting reactions, and VAERS staff do not give medical advice.
The National Vaccine Injury Compensation Program (VICP) is a federal program that was created to compensate people who may have been injured by certain vaccines. Visit the VICP website at www.hrsa.gov/vaccinecompensation or call 1-800-338-2382 to learn about the program and about filing a claim. There is a time limit to file a claim for compensation.
