Rotavirus Vaccination

Pronounced "row-tuh-virus"

Rotavirus vaccination

Rotavirus is the leading cause of severe acute gastroenteritis (vomiting and severe diarrhea) among children worldwide. Two different rotavirus vaccines are currently licensed for infants in the United States. The vaccines are RotaTeq® (RV5) and Rotarix® (RV1). Before being licensed, both vaccines were tested in clinical trials and shown to be safe and effective. In these studies, during approximately the first year of an infant’s life, rotavirus vaccine was found to prevent almost all (85% to 98%) rotavirus illness episodes that were severe and to prevent 74% to 87% of all rotavirus illness episodes.
