| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To demonstrate that the vaccine administered by the intradermal (ID) route with the new Becton Dickinson (BD) ID system (pre-filled ID system allowing a better ergonomic use) is at least as immunogenic as the administration of the vaccine by the intramuscular (IM) route after the first vaccination. |
|
| E.2.2 | Secondary objectives of the trial |
- To describe the safety profile after each vaccine administration. - To describe the effect of the repetition of ID injections and of the interchangeability of ID/IM and IM/ID injections on the safety profile. - To describe the anti-HA antibody persistence after the first injection (at Month 3 [M3], M6 and M12). - To describe the compliance of the immunogenicity of the ID study vaccine with the European Medicines Agency (EMEA) Note for Guidance (CPMP/BWP/214/96) after the first injection. |
