Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Quadrivalent (30 μg) VLP Vaccine | Participants received one IM injection of 0.5 mL of 30 μg/strain of the Quadrivalent VLP Influenza Vaccine on Day 0. | 15 | 6,352 | OG000 | ClinicalTrials.gov |
| Group 2 | Active Comparator (Fluarix) | Participants received one IM injection of 0.5 mL of 15 μg/strain of the Fluarix Quadrivalent® comparator vaccine on Day 0. | 20 | 6,366 | OG001 | ClinicalTrials.gov |

| Title | Number of Participants Who Withdrew Due to an AE | ClinicalTrials.gov |
| Description | An AE or adverse experience was defined as any untoward medical occurrence in a participant or clinical investigation participant who received study drug, with or without a causal relationship with the treatment. An AE can be any favorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not related to a medicinal product. | ClinicalTrials.gov |
| Time frame | Day 0 up to ~9 months | ClinicalTrials.gov |
| Population | SAS. Participants that were non-compliant to protocol/GCP, as per investigator, were excluded from analysis. | ClinicalTrials.gov |
