It is very important that your child return to your doctor's office at the right time for his or her next dose of this vaccine. Be sure to notify your child's doctor of any side effects that occur after your child receive this vaccine.
Make sure your child's doctor knows if your child has any type of cancer or is receiving a treatment that may weaken the immune system (steroid medicine, radiation treatment, or medicine to treat cancer). Tell you child's doctor if your child has received a blood transfusion or blood products within the past 42 days.
Tell your child's doctor if your child spends time with a person who has immune system problems or is receiving cancer treatment. Your doctor may recommend ways (e.g., proper hand washing after changing of diapers) to help prevent the spread of vaccine virus to other people.
Call your child's doctor right away if your child has diarrhea, blood in the stool, a high fever, severe stomach pain, or vomiting. These maybe symptoms of a serious bowel problem called intussusception.
