Haemophilus Influenzae Type B (Hib) Vaccine

Haemophilus Influenzae Type B (Hib) Vaccine

British Columbia Specific Information

Meningitis is an inflammation of the protective lining around the brain and spinal cord. It is a type of meningococcal infection that is usually caused by a virus or bacteria. In British Columbia, there are 2 vaccines that can help protect against meningitis: the Meningococcal C Conjugate (Men-C) Vaccine and the Meningococcal Quadrivalent Vaccine.

The Meningococcal C Conjugate (Men-C) Vaccine is provided free. It is recommended for children at 2 and 12 months of age, and as a booster in grade 6. For more information on this vaccine see HealthLinkBC File #23a Meningococcal C Conjugate (Men-C) Vaccine, and our B.C Immunization Schedules web page.

The Meningococcal Quadrivalent Vaccine is not part of the routine immunization program in B.C. However, it may be recommended by a health care provider for patients that have health concerns or medical conditions that put them at risk of getting sick with meningococcal bacteria. For more information on this vaccine see HealthLinkBC File #23b Meningococcal Quadrivalent Vaccines.

How It Works

Haemophilus influenzae type b (Hib) vaccine is given to protect people from becoming infected with Haemophilus influenzae type b (Hib)  bacteria. The vaccine contains small amounts of weakened bacteria and is given as a shot (injection). This helps your body make chemicals called antibodies  that can then recognize and destroy Hib bacteria if you are exposed to it later.

Why It Is Used

Hib disease can cause meningitis , pneumonia , skin and bone infections, and other serious illnesses in young children. It usually causes problems for children younger than age 5. (It does not cause the flu.)

Hib vaccine is given to protect people from becoming infected with Hib bacteria.

Your child can get Hib disease by being around other children or adults who have the infection and do not know it. The germs spread from person to person. If the germs stay in your child’s nose and throat, your child will probably not get sick. But sometimes the germs cause serious problems when they spread into your child’s lungs or blood.

The National Advisory Committee on Immunization (NACI) recommends that all children should be immunized against Hib at 2, 4 and 6 months with a fourth dose at 18 months. 1 The Hib vaccine may be combined with other vaccines so children only have to receive one shot (known as the 5-in-1, or 6-in-1 shots).

You can keep track of when your child received vaccines using the National Childhood Immunization Record (What is a PDF  document?) or the Alberta childhood immunization record (What is a PDF  document?) .

Children older than age 5 usually do not need Hib vaccine. Some older children and adults may need the shot if they also have other health problems, such as sickle cell disease , HIV , or AIDS . The Hib shot may also be needed if your child has had surgery to remove his or her spleen , a stem cell transplant , or is being treated for cancer.

Side Effects

Hib vaccine is a safe medicine. Side effects are usually mild and may include:

  • Redness, warmth, or swelling where the shot was given.
  • Fever.

Even though serious allergic reactions  are rare with this medicine, call your doctor or public health unit right away if you or your child has trouble breathing, a high fever, or anything unusual after having the shot.

A child who has had a severe allergic reaction to a previous dose of Hib vaccine should not get another dose. Tell your doctor or nurse if you child has had a severe reaction to any vaccine or has severe allergies.

Children that are younger than 6 weeks old should not get the shot until they are older.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

What To Think About

People that are sick at the time that the shot is scheduled should wait until they are feeling better before having the shot.
