* Chronic administration of immunosuppressants or other immune-modifying drugs since birth.
* Planned administration/ administration of a vaccines not foreseen by the study protocol except for DTPw, HBV and OPV vaccines within 14 days before each dose of HRV liquid vaccine or placebo and ending 14 days after.
* Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product (pharmaceutical product or device).
* History of allergic disease or reactions likely to be exacerbated by any component of the HRV liquid vaccine or placebo.
B: Inclusion Criteria:

* Child 9 months of age eligible for measles-rubella vaccination
* documented evidence of a primary rotavirus vaccine series with first dose between 6 and 10 weeks of age and second dose at least 4 weeks after first dose
* healthy infants free of chronic or serious medical condition as determined by history and physical examination at time of study enrollment
* parents/guardians of each participant are able to understand and follow study procedures and agree to participate in study by providing signed informed consent

Exclusion Criteria:

* hypersensitivity to any component of measles-rubella or Rotarix vaccine which would preclude administration of the vaccine
* history of intussusception, intestinal malformations, or abdominal surgery
* known history of measles and/or rubella disease
* history of previous receipt of measles and/or rubella vaccine
* use of any immunosuppressive drugs or immunoglobulin and/or blood products since birth or anticipated during study period
* current enrolment in any other intervention trial or use of any investigational drug or vaccine throughout the study period
* any participant who reports planning to leave the study area before the completion of the study
* acute diarrhea (defined as ≥3 loose stools within a 24-hour period) or vomiting (defined as projectile vomiting or any vomiting at the discretion of the clinician) at the time of enrollment or within the last 24 hours
* acute febrile illness (defined as a temperature of ≥38°C) at the time of enrollment.
C: Inclusion criteria:

* Healthy infants 6 -12 weeks old at Dose 1 with written informed consent.

Exclusion criteria:

* Allergic reaction to vaccine components;
* clinically significant history of chronic GI disease (uncorrected GI congenital malformation) or other serious medical condition per investigator, received vaccines or treatment prohibited by the protocol;
* immunocompromised.
D: Inclusion Criteria:

* Healthy infants of 6 weeks of age (±2 days).
* Study families reside within the Health and Demographic Surveillance System (HDSS) area, service area of the ICDDR,B.
* Family able to understand and comply with planned study procedures

Exclusion Criteria:

* Family residence outside the ICDDR,B HDSS service area, or families expecting to move away during the study period, will be excluded.
* A diagnosis or suspicion of immunodeficiency disorder (either in the infant or in a member of the immediate family).
* A diagnosis or suspicion of bleeding disorder that would contraindicate venipuncture.
* Acute diarrhea, infection or illness at the time of the first visit (6 weeks of age) that would require infant's admission to a hospital or would contraindicate provision of OPV per country guidelines.
* Acute vomiting and intolerance to liquids within 24 hours before the first visit (6 weeks of age).
* Receipt of OPV or IPV at any time before enrollment based upon mother's recall or immunization card if available.
* Because of contact transmission of vaccine poliovirus strains, newborns from multiple births will be excluded from the study to prevent transmission of vaccine strains received during routine immunization from the twin to the study participant.
