One Month after vaccination

Vaccine response was defined as: * for initially seronegative subjects, post vaccination rSBA titer ≥ 1:32 * for initially seropositive subjects, at least 4-fold increase in rSBA titer from pre to post vaccination.

Number of Subjects With rSBA Antibody Titers Greater Than or Equal to the Cut-off Value
Prior to (PRE) vaccination

The cut-off value for the rSBA titers was greater than or equal to (≥) 1:8. This analysis was performed by the GSK Biologicals' laboratory.

Percentage of Subjects With rSBA Antibody Titers Greater Than or Equal to the Cut-off Value
