Primary
| Measure | Time frame |
|---|---|
| Main Objective: To demonstrate the non-inferior (NI) HAI immune response of RIV4 vs licensed IIV4 for the 4 strains based on the egg-derived antigen in all participants aged 3 to 8 years ;Secondary Objective: • To summarize the HAI immune response induced by RIV4 and IIV4 for the 4 strains based on the egg-derived antigen in participants aged 3 to 8 years • To assess the safety profile of each vaccine in all participants and by age group;Primary end point(s): 1- Individual Hemagglutination inhibition (HAI) titer at D29 after vaccination: Antibody titers are expressed as GMTs 2- Percentage of participants achieving seroconversion: Seroconversion for participants with a pre-vaccination titer lower than (<) 10 [1/dil] at D01 and a post-vaccination titer = 40 [1/dil] at D29 or D57, or a pre-vaccination titer = 10 [1/dil] at D1 and a = 4-fold increase in post-vaccination titer at D29 or D57;Timepoint(s) of evaluation of this end point: 1 and 2: Day 29 or Day 57 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1- Individual Hemagglutination inhibition (HAI) titer at Day01 and at D29 after vaccination 2- Percentage of participants with detectable antibody titers greater than or equal to (=) 10 [1/dil] 3- Percentage of participants with antibody titers greater than or equal to (=) 40 [1/dil] 4- Occurrence of immediate adverse events (AEs): Immediate adverse events include unsolicited systemic adverse events within 30 minutes after vaccination 5- Occurrence of solicited injection site reactions and systemic reactions: Adverse reactions pre-listed in the (electronic) case report book (CRB) Injection site reactions: pain, redness, swelling, hardening, bruising Systemic reactions: fever, headache, malaise, myalgia 6- Occurrence of unsolicited AEs: AEs that other than solicited reactions 7- Occurrence of attended adverse event (MAAEs) 8- Occurrence of serious adverse events (SAEs): SAEs, including adverse event of special interest (AESIs);Timepoint(s) of evaluation of this end point: 1, 2 and 3: Day 1 and Day 29 or Day 57 4: Within 30 minutes after each vaccination 5: Within 8 days after each vaccination 6 and 7: Up to 28 days after each vaccination 8: From Day 1 until the EoS (up to 6 months after vaccination) | — |
