Before your child receives this vaccine, be sure to inform your child's doctor of any medical conditions or allergies your child may have, any medications your child is taking, and any other significant facts about your child's health. These factors may affect the vaccine your child is receiving.
Allergic reactions: In rare cases, this vaccine may cause severe allergic reactions. For this reason, doctors often ask people to stay in the office for about 30 minutes after having the vaccine so they can receive medical care if an allergic reaction occurs. If you notice signs of a severe allergic reaction in your child (hives; trouble breathing or swallowing; or swelling of the lips, face, throat, or tongue), get medical attention immediately.
Bleeding disorders: If your child has a bleeding disorder or is taking medications that make them more likely to bleed (i.e., warfarin, acetylsalicylic acid [ASA]) tell the person giving the injection. There is a risk of excessive bleeding where the injection is given if it is not done carefully.
Immune system: As with any vaccine, this vaccine may not be as effective for people with a weakened immune system (e.g., people with AIDS or cancer, people taking antirejection medications after an organ transplant, people receiving chemotherapy, people taking any medication that suppresses the immune system). If your child has a weakened immune system, their doctor may decide to postpone the vaccine till their immune system recovers.
Infection or fever: This vaccine should not be given to anyone who has an active infection or an illness associated with fever, unless the doctor decides that the benefits outweigh the risks.
Seizures: People who have a history of seizures or seizure disorders may be at an increased risk of experiencing seizures with this vaccine. Your child's doctor may suggest that you give your child a dose of medication to prevent fever. If your child has a history of seizures, discuss with their doctor whether any special precautions are needed.
Vaccine protection: As with any vaccine, this vaccine may not protect 100% of people who receive it and may not prevent infection in those people already infected with the bacteria.
Pregnancy and breast-feeding: Studies have not been conducted with this vaccine during pregnancy or breast-feeding. This vaccine is not recommended for anyone 7 years of age or older.
Children: The safety and effectiveness of this vaccine have not been established for infants younger than 2 months or children 2 years of age or older.
