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. | 263 | 6,352 | EG000 | 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. | 266 | 6,366 | EG001 | ClinicalTrials.gov |
