Title: Non-interference and Safety of Concomitant Administration of Measles-rubella and Rotavirus Vaccines at 9 Months of Age in Rural Bangladesh
Brief Summary: The investigators aim to establish the non-inferiority of concomitant administration of measles-rubella and rotavirus vaccines to measles-rubella vaccine given alone in terms of measles seroconversion rates. The primary study hypothesis is the measles seroconversion rate as defined by the percentage of children seroconverting to measles with a measles serum antibody concentration of \>=1:120 at 8 weeks post vaccination after the concomitant administration of measles-rubella and rotavirus vaccines is non-inferior to that obtained when measles-rubella vaccine is given alone in children 9 months of age who have received a primary rotavirus vaccine series with the first dose between 6 and 10 weeks and the second at least 4 weeks later and are seronegative for measles antibody in the pre-vaccination sample.

* Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
* Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
* Planned administration/ administration of a vaccine 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. BCG is administered at birth according to the local EPI.

* Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period.
B: Inclusion Criteria:

* Infants who have received a previous dose of hepatitis B immunoglobulin after birth.

Exclusion Criteria:

* Child in care.
* Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
* Chronic administration of immunosuppressants or other immune-modifying drugs with the exception of Hepatitis B immunoglobulin since birth. Child is unlikely to remain in the study area for the duration of the study.
* Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccine.
* 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.
* Previous vaccination against rotavirus.
* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
* Family history of congenital or hereditary immunodeficiency.
* History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine.
* Major congenital defects or serious chronic illness.
* Acute disease and/or fever at the time of enrolment.
* Administration of immunoglobulins (with the exception of HBIG) and/or any blood products since birth or planned administration during the study period.
* Gastroenteritis within 7 days preceding the study vaccine administration.
* Previous confirmed occurrence of Rotavirus gastroenteritis.
C: Inclusion Criteria:

* 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.
D: Inclusion Criteria:

* Male or female infants who are at least 6 weeks of age and no more than 14 weeks, 6 days of age at Visit 1.
* Parent(s)/legal guardian(s) have signed informed consent documents.
* Children who will be available for the entire study period and whose parents/legal guardians can be reached by telephone.
* Healthy infants as determined by medical history and by a baseline physical examination with no clinically significant abnormal findings within 14 days before the first dose.
* Parents/legal guardians able to complete all relevant study procedures during study participation.

Exclusion Criteria:

* Any clinically significant history of gastrointestinal disease including abdominal surgery or liver disease or other serious medical conditions as determined by the site investigator.
* Any history of immunodeficiency in the infant (e.g., the infant is known to be human immunodeficiency virus (HIV) positive, to have hypogammaglobulinemia, or to have an underlying malignancy), or any infant with any unvaccinated household contact who is immunocompromised such as:

  * Any malignancies or are otherwise immunocompromised;
  * Primary immunodeficiency; or
  * Receiving immunosuppressive therapy.
* Known sensitivity to any vaccine components, such as latex in the Rotarix® applicator.
* Previous receipt of a rotavirus vaccine.
* Acute illness at the time of vaccine administration, such as any of the following within the past 48 hours:

  1. Axillary temperature of 100.4 degrees Fahrenheit or higher, or
  2. More than 3 grossly watery stools, or
  3. Any episodes of vomiting (forceful expulsion of partially digested milk/food). Infants with previous diagnoses of gastroesophageal reflux whose regurgitation episodes have not changed in the 48-hour period prior to the first vaccination may be enrolled.

If these symptoms clear within 48 hours and the subject meets the other inclusion/exclusion criteria, then the subject may be enrolled.

* The subject is currently participating in a study that involves an experimental agent (vaccine, drug, biologic, device, blood product, or medication) or has received an experimental agent within 1 month prior to enrollment in this study, or expects to receive another experimental agent during participation in this study.
* Less than 37 weeks gestation at birth.
* Receipt of blood and/or blood products (including immunoglobulin) within 4 weeks before vaccine administration.
* Receipt of live vaccine within the past 30 days or a nonreplicating, inactivated, or subunit vaccine within the last 14 days, although planned licensed trivalent inactivated influenza vaccine that may be administered to children over 6 months of age during a routine clinic visit is permitted and would not be exclusionary.
* The subject has any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
