General information about the trial
|
|||
Main objective of the trial |
To assess the immune response to the Hib component of GSK Biologicals’ combined DTPa-HBV-IPV/Hib preservative-free vaccine in terms of seroprotection rates one month after the three-dose primary vaccination course in “Aboriginal infants” and “Other Non-Aboriginal infants”.
|
||
Protection of trial subjects |
All subjects were supervised after vaccination/product administration with appropriate medical treatment readily available. Vaccines were administered by qualified and trained personnel. Vaccines were administered only to eligible subjects that had no contraindications to any components of the vaccines.

A seroprotected subject was a subject with anti-HBs antibody concentrations ≥ 10 milli-International Units ler milliliter (mIU/mL). A decrease in the specificity of the anti-HB ELISA assay had been observed in some studies for low levels of antibody (10-100 mIU/mL). The table shows updated results following partial or complete retesting/reanalysis. Some of the available blood samples initially tested with ELISA were re-tested using the new assay, CLIA.

Amendment 2
The protocol was originally designed for sites in British Columbia (BC) and therefore the vaccines that the subject may receive outside of the study were recommended according to the BC vaccination schedule. New sites were selected in provinces where the recommended schedule for vaccine co-administration is different from BC, therefore the protocol is being amended to allow vaccine coadministration according to the provincial schedule rather than the BC schedules.
