It is very important that your child's doctor check your child's progress at regular visits to make sure that this vaccine is working properly and to check for unwanted effects.
Make sure your child's doctor knows if your child is receiving medicine or a procedure that may weaken the immune system, such as steroids, cancer medicines, or radiation. Tell your child's doctor if your child spends time with a person who has an immune system problem or is getting cancer medicines.
The oral applicator of this vaccine contains dry natural latex rubber. Make sure your child's doctor knows if your child has had an allergic reaction to latex rubber.
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 could be symptoms of a serious bowel problem called intussusception.
