How many infants received the RotaShield (rotavirus) vaccine before it was withdrawn from use?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.
