Haemophilus influenzae type b bacteria (Hib) were the leading cause of meningitis in children younger than 5 years old until the Hib vaccine became available. It also used to be a common cause of infections in the ears, lungs, blood, skin, and joints in children.
The Hib vaccine is given by injection at ages:
Kids ages 15 months or older who are receiving the vaccine for the first time only need one dose.
Children ages 12 months to 59 months (almost 5 years old) may need more doses if their immune systems are weakened due to things like asplenia (when the spleen is missing or not working properly), HIV infection, chemotherapy or radiation treatment, or a stem cell transplant.
The vaccine is not routinely recommended for kids older than 5 unless they have a condition that weakens the immune system and have never been vaccinated.
Sometimes doctors give the Hib vaccine in combination with other vaccines, such as DTaP, IPV, or HepB vaccines.
The vaccine provides long-term protection from Haemophilus influenzae type b. Those who are immunized have protection against Hib meningitis; pneumonia; pericarditis (an infection of the membrane covering the heart); and infections of the blood, bones, and joints caused by the bacteria.
Minor problems — such as redness, swelling, or tenderness where the shot was given — can happen. There is a very small chance of an allergic reaction with any vaccine.
The Hib vaccine only contains a small piece of the germ and so it cannot cause Hib disease.
The vaccine is not recommended if your child:
The vaccine may cause mild soreness and redness in the area where the shot was given. For pain and fever, check with your doctor to see if you can give either acetaminophenoribuprofen, and to find out the appropriate dose.
