Study Endpoints
Primary Endpoints
Percentage of Participants With Anti-rotavirus (RV) Immunoglobulin A (IgA) Antibody (Ab) Seroconversion Rate
At Month 2 (1-month post-Dose 2)

Seroconversion rate is defined as the percentage of participants who were initially seronegative (i.e., with anti-RV IgA Ab concentration below \[\<\] 20 unit per milliliter \[U/mL\] prior the first dose of study intervention) and developed anti-RV IgA Ab concentration greater than or equal to (\>=) 20 U/mL at Month 2 (1-month post-Dose 2).

Serum Anti-RV IgA Ab Concentrations Expressed as Geometric Mean Concentrations (GMCs)
At Month 2 (1-month post-Dose 2)
Secondary Endpoints
Percentage of Participants With Serum Anti-RV IgA Ab Concentrations >= 90 U/mL
At Month 2 (1-month post-Dose 2)
Number of Participants Reporting Solicited Systemic Events
Within 14 days (the day of vaccination and 13 subsequent days) after each vaccination (occurring at Day 1 and Month 1)
Number of Participants Reporting Unsolicited Adverse Events (AEs)
Within 31 days (the day of vaccination and 30 subsequent days) after each vaccination (occurring at Day 1 and Month 1)
