Rotavirus is a common virus that causes diarrhea, especially in infants and young children. Childcare centers are a common site of outbreaks.
The vaccine, which is a liquid given by mouth, is recommended at ages 2, 4, and 6 months.
Why the Vaccine Is Recommended
Rotavirus can cause dehydration secondary to large amounts of diarrhea, and can result in children requiring hospitalization. Vaccination against rotavirus can help stop spread in the community, in addition to protecting the individual child.
Possible Risks
Side effects can include diarrhea and vomiting, in addition to fever.
When to Delay or Avoid Immunization
- if your child is currently sick, although simple colds should not prevent immunization
- if your child had an allergic reaction to a previous dose of the vaccine
- if your child has an abnormality of the digestive system or a gastrointestinal disease
- if your child has a history of intussusception, a type of serious bowel blockage
- if your child has recently received gamma globulin or a blood transfusion
- if your child has immune system problems related to cancer, leukemia, or lymphoma; is taking steroids or other immunosuppressive drugs; or is undergoing chemotherapy or radiation therapy
Caring for Your Child After Immunization
Depending on the age of your child, fever may be treated with acetaminophen or ibuprofen. Check with your doctor to see if you can give either medication, and to find out the appropriate dose. If vomiting or diarrhea occur, make sure to give your child small, frequent amounts of fluid and watch for signs of dehydration, such as less urine than usual.
When to Call the Doctor
- if you aren't sure if the vaccine should be postponed or avoided
- if there are problems after the immunization
