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.
Bleeding disorders: If you or your child have a bleeding disorder or are taking medications that make you more likely to bleed (i.e., warfarin, acetylsalicylic acid [ASA]) tell the person giving you the injection. There is a risk of excessive bleeding where you get the injection 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.
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 6 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 6 years of age or older.
