How many infants received the RotaShield® (rotavirus) vaccine before it was withdrawn from use?
In studies before RotaShield® vaccine was licensed, about 7,000 infants received the vaccine. After RotaShield® vaccine was licensed, many more infants were vaccinated during 9 months that the vaccine was available. However, the exact number of infants who received RotaShield® is not known. In the two investigations conducted by CDC, overall, fewer than 13% of infants who were less than one year of age had been vaccinated with one or more dose of the three dose series.
