To assess rotavirus shedding until it stops in HIV infected infants.
To assess enteric pathogens in diarrhoeal stools.
To assess the immune deficiency status (HIV viral load and CD4+ cell counts).
To assess the immunogenicity of routine vaccines (DTPw-HBV/Hib + OPV) two months after the third dose.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
-Subjects who the investigator believed that their parents/guardians could and would comply with the requirements of the protocol (e.g. completion of the diary cards, returned for the follow-up visits) were enrolled in the study.
-A male or female between, and including 6 and 10 weeks of age at the time of the first vaccination.
-Written informed consent obtained from the parents/guardians of the subject
-Documented HIV status of the subject as confirmed by PCR.
-HIV asymptomatic and HIV mildly symptomatic; Stage I and II disease according to WHO’s most recent classifi-cation for HIV stages in infants and children [30 Revised WHO clinical staging of HIV/AIDS for infants and children and 21 Guidelines for the management of HIV-infected children, 2005 or latest updated version].
-Born after a gestation period of 36 to 42 weeks.
|
|
E.4 | Principal exclusion criteria |
-Use of any investigational or non-registered drug or vac-cine other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period.
-Previous routine vaccination except OPV, BCG and HBV vaccination at birth (should have been documented in the CRF).
-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 reaction likely to be exacerbated by any component of the vaccine.
-Acute disease at time of enrolment. (Acute disease was defined as the presence of moderate or severe illness with fever i.e. temperature more than or equal to 38.0°C (more than or equal to 37.5°C) as measured by a rectal (axillary) thermometer) (warrants deferral of the vaccination).
-Gastroenteritis (diarrhoea) within 7 days preceding the study vaccine administration (warrants deferral of the vaccination).
-Previous confirmed occurrence of RV gastroenteritis.
-Other conditions which in the opinion of the investigator might have potentially interfered with interpretation of study outcomes.
