Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each dose of RV3-BB rotavirus vaccine is 1ml sterile cell-free aqueous solution for oral administration, containing RV3-BB live naturally attenuated human rotavirus particles (at a concentration of 8.3E6 FFU/ml), in cell culture medium containing 10% sucrose.

Neonatal Schedule Arm participants will receive three 1ml doses of RV3-BB rotavirus vaccine, with the 1st dose administered at 0-5 days of age, followed by doses at approximately 9 weeks of age and approximately 15 weeks of age. To maintain blinding with the infant schedule arm, the participants in this arm will receive a 1ml dose of placebo at the end of the treatment period (approximately 23 weeks of age).

Infant Schedule Arm participants will receive three 1ml doses of RV3-BB rotavirus vaccine, with the 1st dose administered at approximately 9 weeks of age, followed by doses at approximately 15 weeks of age and approximately 23 weeks of age. To maintain blinding with the neonatal schedule arm, participants in this arm will receive a 1ml dose of placebo at 0-5 days of age.

Outcomes
Primary outcome [1] 285981 0
Vaccine Take (defined as serum immune response or evidence of vaccine shedding in stool)
Timepoint [1] 285981 0
Serology assessments will be done on serum collected at baseline, and 28 days after dose 1, dose 3 (full neonatal vaccine schedule) and dose 4 (full infant vaccine schedule).
Shedding will be assessed in stool collected in the week after each dose.
Secondary outcome [1] 294892 0
Solicited adverse events
Timepoint [1] 294892 0
Solicited Systemic and Gastrointestinal adverse event data will be collected on diary cards in the days 0-7 following each dose. Events will be recorded as they occur.
Secondary outcome [2] 294893 0
Serious Adverse Events (SAE) and unsolicited adverse events
Timepoint [2] 294893 0
Unsolicited adverse event data, including and SAE, will be collected through observation and participant follow-up up from randomisation up to 28 days following the last dose of investigational product. Events will be recorded as they occur.

Eligibility
Key inclusion criteria
healthy, full-term infant, 0-5 days of age.
Minimum age

Sex
Both males and females
Can healthy volunteers participate?

Key exclusion criteria
Moderate or severe illness, major congenital malformations or genetically determined disease, known or suspected disease of the immune system, household member with severe immunosuppression, exposure to the following in the 4 weeks prior to enrolment (including gestation): glucocorticosteroids, cytotoxic drugs or blood products.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computer-generated list of randomization codes will be supplied to the pharmacist involved in the study. At the point of enrolment, the investigator (or delegate) will call the pharmacist and ask for the next randomisation number on the list. That will be the participant number, which will be announced by the pharmacist to the investigator. The investigator and delegates will not be aware of the treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation will be computer generated (by a statistician outside of the study team) using block randomisation, providing allocations for 120 participants in order to accommodate replacement of participants in the event of withdrawal prior to investigational product administration. Randomisation will be stratified by multiple births (single vs multiple).
