| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | D-QIV | Subjects received 1 or 2 doses of candidate influenza Influsplit™ Tetra vaccine (GSK2321138A). | 79 | 5,707 | OG000 | ClinicalTrials.gov |
| Group 2 | Control | In function of their age and Influsplit™ Tetra (D-QIV) vaccine status, subjects received Prevenar 13® or Havrix® Junior and possibly a varicella vaccine (Varilrix® or Varivax/ProVarivax ®). | 216 | 5,697 | OG001 | ClinicalTrials.gov |

| Type | SECONDARY | ClinicalTrials.gov |
| Title | Number of Subjects With First Occurrence of Culture-confirmed Moderate to Severe Influenza A and/or B Disease Due to Any Seasonal Influenza Strain. | ClinicalTrials.gov |
| Description | Attack rate (AR) was defined as the number/percentage of subjects with at least 1 RT-PCR confirmed influenza event. | ClinicalTrials.gov |
| Time frame | During the surveillance period (approximately 6 to 8 months) | ClinicalTrials.gov |
| Population | The ATP cohort for efficacy - Time to event included all eligible subjects who received study vaccine(s) according to their random assignment, for whom vaccine administration site was known, who had a swab collected during the window (0-7 days) of episode onset and who would be censored but not eliminated based on protocol criteria. | ClinicalTrials.gov |
