简要总结
This is a Phase 3, open-label, randomized study to evaluate lot-to-lot consistency in the manufacture of Bovine Rotavirus Pentavalent Vaccine (BRV-PV).
详细描述
The study is designed to evaluate lot-to-lot consistency in the manufacturing of Rotavirus vaccine by testing the vaccine in infants in order to demonstrate equivalence in the induction of specific anti-rotavirus IgA antibodies across three production lots. The study will also examine the potential interference of vaccine with UIP vaccines that will be administered concurrently by assessing non-inferiority in the immune responses to those vaccines when administered with / without the study vaccine.

- •Parental ability and willingness to provide written informed consent.
- •Parent who intends to remain in the area with the child during the study period.
- •Receipt of birth dose of Hepatitis B vaccine and OPV.
排除标准

- •Presence of fever on the day of enrollment (temporary exclusion).
- •Acute disease at the time of enrollment (temporary exclusion).
- •Concurrent participation in another clinical trial at any point throughout the entire timeframe for this study.
- •Presence of significant malnutrition or any systemic disorder as determined by medical history and / or physical examination which would compromise the subject's health or is likely to result in nonconformance to the protocol.
- •History of congenital abdominal disorders, intussusception, or abdominal surgery.
- •Known or suspected impairment of immunological function based on medical history and physical examination.
