Summary

Rotavirus, sometimes called the "stomach flu," is the most common cause of severe diarrhea in children. Vaccines can prevent many types of infections and work by causing the body to make proteins called antibodies that fight infection. For some vaccines, more than one vaccination is needed so that the body will make enough antibodies to fight infection. The vaccines (RotaTeq® or Rotarix® oral vaccines) given in this study are recommended for infants by the Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP). These vaccines require either 2 or 3 vaccinations to be effective. Healthy infants between 6 weeks and 14 weeks, 6 days of age at Visit 1 will participate for about 10-12 months. Study procedures include reaction assessment and blood sample.

Conditions

  • Rotavirus Infection

Interventions

BIOLOGICAL

Rotarix®

Each 1-mL dose of Rotarix® contains a suspension of at least 10\^6 median Cell Culture Infective Dose (CCID50) of live, attenuated human G1P rotavirus after reconstitution. The lyophilized vaccine contains amino acids, dextran, Dulbecco's Modified Eagle Medium (DMEM), sorbitol, and sucrose. The liquid diluent contains calcium carbonate, sterile water, and xanthan. The diluent includes an antacid component (calcium carbonate) to protect the vaccine during passage through the acid environment of the stomach. Rotarix® contains no preservatives. Once reconstituted, the vaccine will appear white and turbid.

BIOLOGICAL

RotaTeq®

2-mL ready-to-use oral solution of live reassortant rotaviruses, containing G1, G2, G3, G4, and P1A, which contains a minimum of 2.0 to 2.8 x 10\^6 infectious units (IU) per individual reassortant dose, depending on the serotype, and not greater than 116 x 10\^6 IU per aggregate dose. The buffered stabilizer solution contains sucrose, sodium citrate, sodium phosphate monobasic monohydrate, sodium hydroxide, polysorbate 80, cell culture media, and trace amounts of fetal bovine serum. RotaTeq® contains no preservatives. RotaTeq® is a pale yellow clear liquid that may have a pink tint.
