Babies might become irritable, or have mild, temporary diarrhea or vomiting after getting a dose of rotavirus vaccine.
Some studies have shown a small increase in cases of intussusception within a week after the fi rst dose of rotavirus vaccine. Intussusception is a type of bowel blockage that is treated in a hospital. In some cases surgery might be required. The estimated risk is 1 intussusception case per 100,000 infants.
What if there is a moderate or severe reaction?
What should I look for?
During the first week after the first dose of vaccine,
look for episodes of stomach pain with severe crying (which may be brief), several episodes of vomiting, or blood in the stool. Your baby could act weak or be very irritable.
Look for any unusual condition, such as a severe allergic reaction or a high fever. If a severe allergic
reaction occurred, it would be within a few minutes to an hour after the vaccination. Signs of a serious allergic reaction can include difficulty breathing, weakness, hoarseness or wheezing, a fast heart beat, hives, dizziness, paleness, or swelling of the throat.
What should I do?
Call a doctor, or get the person to a doctor right away.
Tell your doctor what happened, the date and time it happened, and when the vaccination was given.
Ask your provider to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS) form. Or you can file this report through the VAERS website at www.vaers.hhs.gov
, or by calling 1-800-822-7967.
