For the Consumer

Applies to haemophilus b conjugate (prp-t) vaccine / meningococcal conjugate vaccine: intramuscular powder for injection

Your child should not receive a booster vaccine if he or she had a life threatening allergic reaction after the first shot. Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shot caused any side effects.

Becoming infected with haemophilus B influenza or meningitis is much more dangerous to your child's health than receiving this vaccine. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.

Get emergency medical help if your child has any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if the child has a serious side effect such as:

• severe weakness, trouble breathing;

• extreme drowsiness, fainting;

• fussiness, irritability, crying for an hour or longer;

• seizure (convulsions); or

• high fever (within a few hours or a few days after the vaccine).

Less serious side effects of haemophilus b conjugate (prp-t) vaccine / meningococcal conjugate vaccine may include:

• redness, pain, swelling, or a lump where the shot was given;

• low fever;

• mild fussiness or crying;

• loss of appetite;
