Title: A Phase IIIb, Partially Blind, Randomized, Placebo-controlled Study to Asses the Effect on Immunogenicity of Administration of Vaccine Without Buffering Agent and to Assess Heat Stability in Terms of Immunogenicity, Reactogenicity and Safety of GlaxoSmithKline Biologicals' Oral Live Attenuated Human Rotavirus (HRV) Vaccine Following a 0, 2 Month Schedule, in Healthy Infants Previously Uninfected With Human Rotavirus
Brief Summary: Rotavirus (RV) is the most important cause of acute gastroenteritis (GE) requiring hospitalization of infants and young children in developed and developing countries and can be a frequent cause of death in children less than 5 years of age. GSK Biologicals has developed a vaccine against human rotavirus gastroenteritis. In this study, the immunogenicity, reactogenicity and safety of the HRV vaccine will be evaluated when stored or reconstituted in circumstances different from the recommendations: i.e. when not reconstituted with a buffer or when stored for 7 days at 37°C before reconstitution. In addition, the effect of feeding will be explored for HRV vaccine reconstituted without buffer.


Options:
A: Inclusion Criteria:

* Healthy infants birth weigh \>2000 g, 11 -17 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.
B: INCLUSION CRITERIA:

* A male or female between, and including, 6 and 12 weeks (42-90 days) of age at the time of the first vaccination.
* Written informed consent obtained from the parent or guardian of the subject.
* Free of obvious health problems as established by medical history and clinical examination before entering into the study.

EXCLUSION CRITERIA:

* Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine or placebo, or planned use during the study period.
* Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs prior to the first vaccine dose, since birth. (For corticosteroids, this will mean prednisone, or equivalent, greater than or equal to 0.5 mg/kg/day. Inhaled and topical steroids are allowed.)
* Planned administration of a vaccine (except routine paediatric vaccines) not foreseen by the study protocol. (If exceptionally OPV is given, this should be administered at least 14 days apart from the HRV vaccine or placebo dose.)
* Any clinically significant history of chronic gastrointestinal disease including any uncorrected congenital malformation of the GI tract or other serious medical condition as determined by the investigator.
* History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
* Any confirmed or suspected immunosuppressive or immunodeficient condition based on medical history and physical examination (no laboratory testing is required).
* Major congenital defects or serious chronic illness.
* Gastroenteritis within 7 days preceding the study vaccine administration (warrants deferral of the vaccination).
* Administration of immunoglobulins and/or blood products since birth or planned administration during the study period. Oral intake of immunoglobulins via e.g. breastfeeding is allowed.
* Previous confirmed occurrence of RV gastroenteritis.
C: Inclusion Criteria:

* Healthy infants at least 6 weeks (42 days) and up to 12 weeks (84 days) of age at the time of the first study vaccination
* Parent/legal guardian agrees to participate by giving written informed consent and is willing and able to comply with study requirements

Exclusion Criteria:

* History of congenital abdominal disorders, prior rotavirus gastroenteritis, chronic diarrhea, failure to thrive, or abdominal surgery
* History of intussusception
* Impairment of immunological function, including Severe Combined Immunodeficiency (SCID)
* Acute disease, severe chronic disease, or chronic disease during the acute period
* Uncontrolled epilepsy, encephalopathy, seizure, or other progressive neurological disease
* Hypersensitivity to any component of the rotavirus vaccine, OPV, or DTaP
* Prior receipt of any rotavirus vaccine
* Fever, with an axillary temperature \>=37.5 °C (or equivalent) within 24 hours before study vaccination (study vaccination can be deferred until complete resolution of febrile illness)
* Clinical evidence of active gastrointestinal illness
* Received intramuscular, oral, or intravenous corticosteroid treatment since birth (topical, ophthalmic, and inhaled steroids are permitted)
* Resides in a household with an immunocompromised person
* Receipt of a blood transfusion or blood products, including immunoglobulins
* Participation in another interventional study within 14 days before the first study vaccination or during the study
* Receipt of an investigational or non-registered product other than the study vaccine within 30 days before the first study vaccination or during the study
* For participants in immunogenicity arms: inability to obtain a blood specimen at randomization visit (note: the visit may be rescheduled so that a baseline specimen may be obtained); history of polio, diphtheria, tetanus, or pertussis disease; previous vaccination against diphtheria, tetanus, pertussis, or poliomyelitis
* Any condition which, in the opinion of the investigator, may interfere with the evaluation of the study objectives
D: Inclusion Criteria:

* Between 42 and 55 days of age at the time of enrollment.
* Healthy infant free of chronic or serious medical condition as determined by history and physical examination at the time of study enrollment.
* Parents/guardians of each subject are able to understand and follow study procedures and agree to participate in the study by providing parental/guardian permission.

Exclusion Criteria:

* If child has previously had intussusception or abdominal surgery.
* Use of any immunosuppressive drugs or immunoglobulin and/or blood product use since birth or anticipated during study period.
* Current enrollment in any other intervention trial or use of any investigational drug or vaccine throughout the study period.
* Birthweight less than 2000 grams or gestation \< 36 weeks, if this information is available.
* Any subject who reports plan to leave the study area before the completion of the study (i.e., relocation, migration, etc.).
* Another child living in the same compound is already enrolled in the trial (i.e., only one participant can be enrolled per compound).
* After the rotavirus vaccine is introduced into the routine EPI system in Navrongo: Another child in the compound is less than 16 weeks of age.
* The child has received rotavirus vaccine outside of this study.
