结局指标
主要结局
Number of Seroconverted Subjects Against Human Rotavirus
时间窗: At 1 to 2 months after the second vaccine dose (Months 3-4)
A seroconverted subject was defined as a vaccinated subject who had an anti-rotavirus IgA antibody concentration equal to or above (≥) 20 units per milliliter (U/mL) and who was initially (i.e. prior to the first dose of Rotarix™ vaccine) negative for rotavirus.
次要结局
- Concentrations of Anti-rotavirus IgA Antibodies(At 1 to 2 months after the second vaccine dose (Months 3-4))
- Number of Subjects With Vaccine Take for Anti-rotavirus IgA Antibodies(At 1 to 2 months after the second vaccine dose (Months 3-4))
- Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms(During the 15-day (Day 0-14) follow-up period, after each vaccine dose and across doses, up to 4 months.)
- Number of Subjects With Unsolicited Adverse Events (AEs)(Within 31 days after any vaccine dose (Day 0-30) post-vaccination, up to 4 months)
- Number of Subjects With Serious Adverse Events (SAEs)(Throughout the entire study period (from Day 0 to Month 4))
- Number of Subjects With Rotavirus in Stool Samples Collected During Gastroenteritis Episodes(From the first vaccine dose (Dose 1) up to Month 4)
