PRIMARY outcome

Timeframe: At Day 7 post dose 1

Population: Analyses was performed on According-to-Protocol cohort for immunogenicity (ATP-I) excluding subjects who had an RT-PCR confirmed influenza infection in study 115345 consisted of all evaluable subjects from the ATP-I, excluding subjects who had an RT-PCR confirmed influenza infection in study 115345.

Mean geometric increase was defined as the geometric mean of the within subject ratios of the post-vaccination reciprocal HI titer to the Day 0 reciprocal HI titer. The vaccine strains included A/Christchurch/16/2010 (H1N1), A/Victoria/361/2011(H3N2), B/Brisbane/60/2008 (Victoria) and B/Hubei-Wujiagang/158/2009 (Yamagata) antigens.

Timeframe: At Day 7 post dose 1

Population: Analysis was performed on According-to-Protocol (ATP) cohort for immunogenicity which included all evaluable subjects who received study vaccine according to their treatment assignment, for whom assay results for antibodies against at least 1 study vaccine strain after vaccination and data concerning immunogenicity outcome measures were available.

MGI was defined as the fold increase in serum HI GMT post-vaccination compared to Day 0. The vaccine strains included A/Christchurch/16/2010 (H1N1), A/Victoria/361/2011 (H3N2), B/Brisbane/60/2008 (Victoria) and B/Hubei-Wujiagang/158/2009 (Yamagata) antigens.

SECONDARY outcome

Timeframe: At Day 7 post dose 1

Population: Analyses was performed on According-to-Protocol cohort for immunogenicity (ATP-I) excluding subjects who had an RT-PCR confirmed influenza infection in study 115345 consisted of all evaluable subjects from the ATP-I, excluding subjects who had an RT-PCR confirmed influenza infection in study 115345.

MGI was defined as the fold increase in GMTs post-vaccination compared to Day 0. The vaccine strains included A/Christchurch/16/2010 (H1N1), A/Victoria/361/2011 (H3N2), B/Brisbane/60/2008 (Victoria) and B/Hubei-Wujiagang/158/2009 (Yamagata) antigens.

Population: Analysis was performed on According-to-Protocol (ATP) cohort for immunogenicity which included all evaluable subjects who received study vaccine according to their treatment assignment, for whom assay results for antibodies against at least 1 study vaccine strain after vaccination and data concerning immunogenicity outcome measures were available

Antibody titers were expressed as geometric mean titers. The vaccine strains included A/Christchurch/16/2010 (H1N1),A/Victoria/361/2011 (H3N2), A/Victoria/361/2011 and B/Hubei-Wujiagang/158/2009)(Yamagata) antigens. The humoral response in terms of neutralising antibodies for all vaccine strains were calculated by age stratum which included 17-29 months and 30-48 months age groups for both the Fluarix primed and unprimed groups.

SECONDARY outcome

Timeframe: At Day 7 post dose 1

Population: Analyses were performed on the ATP cohort for immunogenicity which included all evaluable subjects who received the study vaccine according to their treatment assignment, for whom the assay results for antibodies against at least one study vaccine strain after vaccination and for whom data concerning immunogenicity outcome measures were available

MGI was defined as the fold increase in GMTs post-vaccination compared to Day 0. The vaccine strains included A/Christchurch/16/2010 (H1N1), A/Victoria/361/2011 (H3N2), B/Brisbane/60/2008 (Victoria) and B/Hubei-Wujiagang/158/2009 (Yamagata) antigens. The humoral response in terms of anti-neuraminidase antibodies for all vaccine strains were calculated by age stratum which included 17-29 months and 30-48 months age groups for both the Fluarix primed and unprimed groups.
