Geometric Mean Titers of the Cell Culture-derived Vaccine Compared With the Egg-derived Vaccine in 3 to 8 Year-old Children
Zeitfenster: Day 50 post vaccination
|
To demonstrate non-inferiority of the post vaccination hemagglutination inhibition (HI) geometric mean titer (GMT) of the cell culture-derived influenza (cTIV) vaccine to the corresponding GMT of the egg-derived (eTIV) influenza vaccine, for all three strains, after two injections administered four weeks apart to a subset of children 3 to 8 years of age. GMTs were evaluated using two assays, HI egg derived antigen assay and HI cell derived antigen assay. |
