Before your child receives this vaccine, be sure to inform your 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. If you notice signs of a severe allergic reaction (e.g., hives; trouble breathing or swallowing; or swelling of the lips, face, throat, or tongue), get medical attention immediately.
Bleeding: If your child has a bleeding disorder or is taking anticoagulants (blood thinners), discuss with their doctor how this vaccine may affect their medical condition and whether any special monitoring is needed.
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, or 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: Your child’s doctor may decide to delay this vaccine if your child has an acute infection or fever. Mild infections without fever, such as colds, usually do not require delay of the vaccine.
Seizures: If your child has an increased risk of seizures, their doctor may suggest that a medication to prevent fever (e.g., acetaminophen) be given at the time of vaccination and for 24 hours after the vaccine.
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 or virus.
Pregnancy and breast-feeding: This medication should not be administered to women who are pregnant or breast-feeding.
Children: This medication is not recommended for children under 2 months of age.
