Participant flow

The study included a first 385-days Blinded Phase (all subjects), followed by a 385-days Unblinded Phase. In this phase, subjects who received the placebo in the Blinded Phase were offered, after completing the Blinded Phase, 2 doses of Influenza A (H5N1) Virus monovalent vaccine administered for Dose 1 within a short delay of Day 385 (Day U0).

As the analyses were performed and disclosed stepwise - i.e. as soon as a study phase was completed - several releases of the CTRS (result summaries) were published. To generate an integrated Clinical Study Report, one set of domain datasets covering all analyses was used and the Adapted ATP cohort for immunogenicity has been defined. As a consequence, some of the data previously disclosed and based on ATP cohort for immunogenicity at Day 42, Day 182 and Day 385 have been replaced in this summary with data generated with the Adapted ATP cohort for immunogenicity.
