Primary Outcome Measures:
  • Efficacy Against Rotavirus Gastroenteritis of Any Severity Caused by Rotavirus Serotypes G1, G2, G3, G4 and G-serotypes Associated With Serotype P1 [ Time Frame: At least 14 days following the 3rd vaccination ] [ Designated as safety issue: No ]

    Any severity cases of rotavirus gastroenteritis caused by G1, G2, G3, G4 or G-serotypes associated with serotype P1 occurring at least 14 days postdose 3 in the per-protocol population using per-protocol case definition.

    Vaccine Efficacy is defined as: 1-Relative Risk (RR), expressed as a percentage; the RR is the incidence in the vaccine group / the incidence in the placebo group.



Secondary Outcome Measures:
  • Efficacy Against Moderate to Severe Rotavirus Gastroenteritis Caused by Rotavirus Serotypes G1, G2, G3, G4 and G-serotypes Associated With Serotype P1A. [ Time Frame: At least 14 days following the 3rd vaccination ] [ Designated as safety issue: No ]

    Moderate to severe cases of rotavirus gastroenteritis caused by G1, G2, G3, G4 or G-serotypes associated with serotype P1 occurring at least 14 days postdose 3 in the per-protocol population using per-protocol case definition Vaccine Efficacy is defined as: 1-Relative Risk (RR), expressed as a percentage; the RR is the incidence in the vaccine group / the incidence in the placebo group.

    Severity score was calculated based on frequency and duration of diarrhea, vomiting, elevated temperature, and behavioral changes. Score of >8 and <=16 was considered moderate, and >16 was considered severe.


  • Efficacy Against Severe Rotavirus Gastroenteritis Caused by Rotavirus Serotypes G1, G2, G3, G4 and G-serotypes Associated With Serotype P1A [ Time Frame: At least 14 days following the 3rd vaccination ] [ Designated as safety issue: No ]

    Severe cases of rotavirus gastroenteritis caused by G1, G2, G3, G4 or G-serotypes associated with serotype P1 occurring at least 14 days postdose 3 in the per-protocol population using per-protocol case definition Vaccine Efficacy is defined as: 1-Relative Risk (RR), expressed as a percentage; the RR is the incidence in the vaccine group / the incidence in the placebo group.

    Severity score was calculated based on frequency and duration of diarrhea, vomiting, elevated temperature, and behavioral changes. Score of >8 and <=16 was considered moderate, and >16 was considered severe.



Other Outcome Measures:
  • Occurrence of Rotavirus Gastroenteritis of Any Severity Caused by Rotavirus Serotypes G1, G2, G3, G4 and G-serotypes Associated With Serotype P1 [ Time Frame: At least 14 days following the 3rd vaccination ] [ Designated as safety issue: No ]
    Any severity cases of rotavirus gastroenteritis caused by G1, G2, G3, G4 or G-serotypes associated with serotype P1 occurring at least 14 days postdose 3 in the per-protocol population using per-protocol case definition.

  • Occurrence of Moderate to Severe Rotavirus Gastroenteritis Caused by Rotavirus Serotypes G1, G2, G3, G4 and Gserotypes Associated With Serotype P1A. [ Time Frame: At least 14 days following the 3rd vaccination ] [ Designated as safety issue: No ]

    Moderate to severe cases of rotavirus gastroenteritis caused by G1, G2, G3, G4 or G-serotypes associated with serotype P1 occurring at least 14 days postdose 3 in the per-protocol population using per-protocol case definition.

    Severity score was calculated based on frequency and duration of diarrhea, vomiting, elevated temperature, and behavioral changes. Score of >8 and <=16 was considered moderate, and >16 was considered severe.


  • Occurrence of Severe Rotavirus Gastroenteritis Caused by Rotavirus Serotypes G1, G2, G3, G4 and G-serotypes Associated With Serotype P1A [ Time Frame: At least 14 days following the 3rd vaccination ] [ Designated as safety issue: No ]

    Severe cases of rotavirus gastroenteritis caused by G1, G2, G3, G4 or G-serotypes associated with serotype P1 occurring at least 14 days postdose 3 in the per-protocol population using per-protocol case definition.

    Severity score was calculated based on frequency and duration of diarrhea, vomiting, elevated temperature, and behavioral changes. Score of >8 and <=16 was considered moderate, and >16 was considered severe.
