Haemophilus b conjugate (PRP-OMP) vaccine

Haemophilus influenzae type B (Hib) is a bacteria that can cause serious illnesses, such as breathing problems or meningitis. Hib infection mainly affects children and can be fatal.

Haemophilus b conjugate (PRP-OMP) vaccine is used to help prevent this disease in infants and children aged 2 to 71 months.

The vaccine works by exposing your child to a small amount of the bacteria or a protein from the bacteria, which helps the body develop immunity to the disease. This vaccine will not treat an active infection that is already present in the body and will not protect against other types of influenza.

Haemophilus b conjugate (PRP-OMP) vaccine is not for use in children younger than 6 weeks or older than 71 months of age.

Like any vaccine, haemophilus b conjugate (PRP-OMP) vaccine may not provide protection from disease in every person.

This vaccine is given as an injection into a muscle. Your child will receive this injection at a doctor's office or clinic.

This vaccine is given in a series of shots. The first shot is usually given when the child is 2 months old, followed by another dose two months later. If the child receives the two-dose series before 12 months of age, a booster shot is required at 12 to 15 months of age.

For children who do not start this series of shots before 15 months of age, the vaccine is usually given as a one-time injection. Unless your doctor tells you otherwise, you will not need a booster vaccine.

Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of your state.

Your doctor may suggest treating fever and pain with a pain reliever that does not contain aspirin, such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much haemophilus b conjugate (PRP-OMP) vaccine to give your child.

It is especially important to prevent fever in a child who has a seizure disorder such as epilepsy.

Tell your doctor if your child takes any other medicines, has other medical conditions, or has allergies.

Your child should not get this vaccine if he or she has ever had an allergic reaction to a haemophilus B or meningococcal vaccine.

If your child has any of these other conditions, this vaccine may need to be delayed or not given at all:

• severe immune suppression caused by disease (like cancer, HIV, or AIDS), or by taking certain medicines like steroids, chemotherapy, or radiation;
• a history of seizures; or
• an allergy to latex rubber.

Get emergency medical help if your child shows signs of an allergic reaction: hives; trouble breathing; swelling of the face, lips, tongue, or throat.

Keep track of any side effects your child experiences after getting this vaccine. When your child receives a booster dose, inform the doctor if the previous shot caused any side effects.

Call your doctor immediately if your child has:

• a high fever (within a few hours or a few days after the vaccine);
• a seizure; or
• fussiness, irritability, or crying for an hour or longer.

Common side effects of haemophilus b conjugate (PRP-OMP) vaccine may include:

• irritability, crying;
• drowsiness;
• diarrhea, vomiting;
• rash;
• pain, swelling, or redness at the injection site;
• cold symptoms like stuffy nose, sneezing, sore throat; or
• ear infection—fever, ear pain or full feeling, trouble hearing, drainage from the ear, fussiness in a child.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.
