RotaTeq is a vaccine that can help prevent rotavirus gastroenteritis in infants—a leading cause of severe diarrhea among infants and young children.


Every year in the United States, rotavirus is estimated to be responsible for up to 70,000 hospitalizations and approximately 250,000
emergency-room visits among children younger than 5 years of age.
RotaTeq is not a shot-it is given by mouth in 3 doses.
• Your doctor or health care professional can give the first dose of RotaTeq to your baby starting as early as 6 weeks of age. The third dose should be given before 32 weeks (8 months) of age.
• Rotavirus can cause mild, moderate, or severe symptoms. There is no reliable way to predict which babies will have serious cases.
• Rotavirus can cause high fever, multiple episodes of vomiting and diarrhea, and can quickly lead to dehydration (loss of body fluids).
• Dehydration is the most serious complication associated with rotavirus infection. If your baby has a severe case of rotavirus and becomes very dehydrated, it can be life threatening.
• RotaTeq was extensively tested in a large study and was approved by the Food and Drug Administration (FDA) in February 2006.
• Talk to your doctor or health care professional today about RotaTeq.
Important Safety Information
The most common side effects reported were diarrhea, vomiting, fever, runny nose, sore throat, wheezing or coughing, and ear infection. Ask your doctor or health care professional for a more complete list of side effects. Call your child's doctor right away if your child has vomiting, diarrhea, severe stomach pain, blood in their stool or change in their bowel movements, as these may be signs of a serious and life-threatening condition known as intussusception. It is important to contact your health care professional if your child has any of these symptoms at any time after vaccination. RotaTeq should not be given to infants who are allergic to any part of the vaccine.
