| NCT00652743 | Immunogenicity of GSK Biologicals' Pandemic Influenza Vaccine (GSK1562902A) at Different Boosting Vaccination Schedules | PHASE3 | COMPLETED | 845 | — | — | Mar 23, 2008 | Jun 8, 2011 | Aug 2, 2018 | 6 | Hong Kong, Singapore +2 |
Seropositivity cut-off values assessed were equal to or above (≥) 1:10 in the sera of subjects seronegative before vaccination. The flu strain assessed was Flu A/Indonesia/05/2005.
Titers are presented as geometric mean titers (GMTs). The reference seropositivity cut-off value was equal to or above (≥) 1:10. The flu strain assessed was Flu A/Indonesia/05/2005.

Titers are presented as geometric mean titers (GMTs). The reference seropositivity cut-off value was equal to or above (≥) 1:10. The flu strain assessed was Flu A/Indonesia/05/2005.
Booster vaccine response was defined as: antibody titer after booster vaccination ≥ 4-fold the pre-booster antibody titer. The Flu strain assessed was A/Indonesia/05/2005 (H5N1).
Booster vaccine response was defined as: antibody titer after booster vaccination ≥ 4-fold the pre-booster antibody titer. The Flu strain assessed was A/Indonesia/05/2005 (H5N1).
GMFR, also known as seroconversion factor (SCF), was defined as the geometric mean of the within-subject ratios of the post-vaccination reciprocal HI titer to the pre-vaccination reciprocal HI titer for the vaccine virus. The flu strain assessed was Flu A/Indonesia/05/2005.
GMFR, also known as seroconversion factor (SCF), was defined as the geometric mean of the within-subject ratios of the post-vaccination reciprocal HI titer to the pre-vaccination reciprocal HI titer for the vaccine virus. The flu strain assessed was Flu A/Indonesia/05/2005.
Seroprotection (SPR) was defined as the proportion of subjects with H5N1 reciprocal HI titers equal to or above (≥) 1:40 against the tested vaccine virus. The flu strain assessed was Flu A/Indonesia/05/2005.
