| NCT00363077 | Study to Evaluate the Immunogenicity and the Safety of an Adjuvanted Influenza Vaccine Candidate | PHASE2 | COMPLETED | 150 | — | — | Oct 2, 2006 | Nov 17, 2006 | Jun 8, 2018 | 1 | Belgium |
Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia. The seropositivity cut-off assay was 1:10.
A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer \<1:10 and a post-vaccination titer ≥1:40 or a pre-vaccination titer ≥1:10 and at least a four-fold increase in post-vaccination titer. The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia.
A seroprotected subject was defined as a vaccinated subject who had a serum HI titer ≥ 1:40. The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia.
The seroconversion factor (SCF) was defined as the fold increase in serum Hemagglutination Inhibition (HI) geometric mean titers (GMTs) post vaccination compared to Day 0. The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia.
