This vaccine helps protect young children from Haemophilus influenzae type b (Hib) infection. Hib is a bacterial infection that can cause serious illness, including brain infection (meningitis). Children younger than age 5 are at highest risk for infection. Vaccination is the best way to protect against this life-threatening disease. Vaccines work by causing the body to produce its own protection (antibodies).
This vaccine is not usually used in children over the age of 5 or in adults.
A series of injections is needed to provide the best protection. It is very important that your child receive all the injections ordered by the health care professional, or the vaccine may not work as well. Keep all scheduled medical appointments.
Vaccines are usually given in a series of doses to provide the best protection. Closely follow the vaccination schedule provided by your health care professional. Keep all scheduled medical appointments. It may be helpful to mark a calendar as a reminder. There are various combinations of vaccines available. Based on your age, vaccination history, and previous reaction to vaccines, your health care professional will decide which vaccines are best for you. Discuss the risks and benefits of vaccination with your health care professional.
Hib vaccine can be given at the same time as the other usual childhood vaccinations (e.g., diphtheria/tetanus/pertussis, hepatitis, polio) either in the same injection or using a separate needle and injection site, depending on the types of vaccine being given.
Pain, swelling, and redness at the injection site may occur. Drowsiness, irritability/crying, loss of appetite, diarrhea, fever, or vomiting may also occur. If any of these effects persist or worsen, notify the health care professional promptly.
Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care professional right away if your child has any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms.
Remember that your health care professional has prescribed this medication because he or she has judged that the benefit to your child is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Get medical help right away if your child has any very serious side effects, including: seizures, unresponsiveness.
