Reporting Groups
  Description
RotaTeq™ Three oral doses (~6.5x10^7 to ~1.2x10^8 IU/dose) of RotaTeq™ (rotavirus vaccine, live, oral, pentavalent) administered at 3 separate visits scheduled 4 to 10 weeks (28 to 70 days) apart.
Placebo Placebo matching RotaTeq™ administered at 3 separate visits scheduled 4 to 10 weeks (28 to 70 days) apart.

[1] The eligibility for this study was to enroll infants 6-12 weeks of age; however infants that were 5 weeks and under, and infants who were 12 weeks and over were inadvertently enrolled outside these ranges. Those infants who received at least 1 dose of study vaccine, were followed for safety.
