Are there any side effects from the rotavirus vaccine?
Slight side effects are associated with the rotavirus vaccine. Within a week of getting a dose, babies are slightly more likely to have mild, temporary diarrhea or vomiting.
In the 1990s a different kind of rotavirus vaccine was developed, but was soon taken off the market. In rare cases, this version of the vaccine could cause a type of bowel obstruction called intussusception. But before the Food and Drug Administration approved today's rotavirus vaccine (RotaTeq), it was safely tested in more than 70,000 children with no serious side effects. Experts agree that the current version of the vaccine is very safe.
As with any vaccine, severe allergic reactions are very rare, but possible. If you notice your child having difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, dizziness, or a rapid heartbeat shortly after receiving a shot, call your doctor right away.
