Menhibrix (PF) intramuscular

Name: Menhibrix (PF) intramuscular


This vaccine is used for high-risk infants to help prevent serious, sometimes fatal infections caused by 2 different bacteria (Haemophilus influenzae type b and Neisseria meningitides groups C and Y). These infections are very serious and may cause severe problems (such as hearing loss, brain/nerve problems, paralysis, blindness, seizures, loss of limbs) even with proper antibiotic treatment. Therefore, preventing these infections through vaccination is very important.

This vaccine contains parts from the bacteria. It works by causing the body to produce its own protection (antibodies) against the bacteria.

This vaccine is not approved for use by children over 18 months of age or by adults.

This vaccine does not provide protection against all types of Neisseria meningitides. Another vaccine may be required. Ask your health care professional for more details.

How to use Menhibrix Vial

Read all vaccine information available from your health care professional before receiving the vaccine. If you have any questions, ask your health care professional.

This vaccine is given by injection into the muscle by a health care professional.

A series of 4 injections is needed to provide the best protection. They are usually given when the infant is aged 2 months, 4 months, 6 months, and 12 to 15 months. 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.

Side Effects

Pain, swelling, and redness at the injection site may occur. Drowsiness, irritability/crying, loss of appetite, or fever may also occur. If any of these effects persist or worsen, tell 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 vaccine because he or she has judged that the benefit to your child is greater than the risk of side effects. Many children receiving this vaccine do not have serious side effects.
