Primary Outcome(s)
|
Primary end point(s): - Anti-hemagglutinin (HA) antibody titers for the three strains, 21 days (D21) after the first vaccination. - Seroprotection status: anti-HA antibody individual titer = 40 (1/dil), 21 days (D21) after the first vaccination.
|
Secondary Objective: Immunogenicity: -To describe the antibody persistence induced by both vaccines at 3, 6 and 12 months after the 1st vaccination in a subset of subjects. -To describe the immunogenicity of the ID investigational vaccine after each vaccination using parameters defined in the EMEA Note for Guidance (CPMP/BWP/214/96) specific to elderly subjects.
Safety: -To demonstrate that the ID investigational vaccine is at least as well tolerated as the IM reference vaccine after the first vaccination, in terms of proportions of subjects with any moderate or severe solicited systemic reaction. -To describe the safety profile after each vaccination. -To describe the effect of repetitive ID injections on the safety profile.
Comfort of the vaccination assessment
|
Main Objective: To demonstrate that the intradermal (ID) investigational vaccine induces a better immunogenicity than the intramuscular (IM) reference vaccine in terms of seroprotection rate after the first vaccination
