ABOUT THE VACCINE
The Hib vaccine protects against infection from the bacteria Haemophilus influenzae type b (Hib). Hib can cause serious and life-threatening infections, including meningitis, an infection of the lining that covers the brain, and septicemia, an infection of the blood. Despite its name, this disease is not the same as influenza (the flu).
The Hib vaccine is recommended for all children younger than 5 years of age. Some older children and adults with certain medical conditions should also get the vaccine. The Hib vaccine is usually combined with other vaccines so that you or your child can get protection against several diseases with fewer needles. There are many different vaccines used to prevent Hib.

Diphtheria, Tetanus, Pertussis, Hepatitis B, Polio, and Haemophilus influenzae type b (DTaP-HB-IPV-Hib) Vaccine
- This vaccine is given to babies as a series of 3 doses at 2, 4, and 6 months of age. They should get this vaccine at the same time as other childhood immunizations.
- This vaccine is given to children as a booster dose at 18 months of age after completing a three-dose primary series of DTaP-HB-IPV-Hib.
- This vaccine is given to some people 5 years of age and older with certain medical conditions.
The Hib vaccine is the best way to protect against Hib infection, a serious disease that sometimes causes death.
Vaccines are very safe. It is much safer to get the vaccine than it is to get Hib.
Many people have no side effects from these vaccines. For those that do, side effects are usually mild and last 1 to 2 days (see a list of common side effects for each vaccine below). Serious side effects are very rare.
It is important to stay in the clinic for 15 minutes after getting any vaccine because there is an extremely rare possibility of anaphylaxis, which is a life-threatening allergic reaction. This may include hives, difficulty breathing, or swelling of the throat, tongue, or lips. The chance of true anaphylaxis is about 1 in 1 million vaccine doses. Should this reaction occur, your health care provider is prepared to treat it. Emergency treatment includes administration of epinephrine (adrenaline) and transfer by ambulance to the nearest emergency department. If symptoms develop after you leave the clinic, call 9-1-1 or the local emergency number. Learn more about anaphylaxis on our vaccine side effects page.
It is important to always report serious or unexpected reactions to your immunizing health care provider.
Common side effects may include soreness, redness, and swelling where the vaccine was given. Some children may have a fever or experience crankiness, restlessness, vomiting, diarrhea, persistent crying, or a loss of appetite. These reactions are mild and usually last 1 to 2 days.

ABOUT THE DISEASE
- Hib is a bacteria that most commonly infects children under 5 years of age.
- Hib infection is spread by coughing, sneezing, or close face-to-face contact. Babies and children can become sick through sharing soothers, bottles or toys used by other children.
- Hib can cause serious and life-threatening infections, including meningitis, an infection of the lining that covers the brain, and septicemia, an infection of the blood.
- In the early 1990s, Hib was the most common cause of bacterial meningitis in children younger than 5 years of age in Canada. Hib is now rare in Canada because of routine childhood vaccination programs.
