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. | 28 | 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. | 51 | 6,366 | OG001 | ClinicalTrials.gov |

| Type | SECONDARY | ClinicalTrials.gov |
| Title | Number of Participants With ≥ Severe Related Solicited Reactions | ClinicalTrials.gov |
| Description | Participants were monitored for both solicited local reactions (erythema, swelling, \& pain at the injection site) \& solicited systemic reactions (fever, headache, fatigue, muscle aches, joint aches, chills, a feeling of general discomfort, swelling in axilla, \& swelling in neck). The intensity of solicited reactions was graded as mild (1)-easily tolerated and does not interfere with usual activity; moderate (2)-interferes with daily activity, but the participant is still able to function; severe (3)-incapacitating and the participant is unable to work or complete usual activity or potentially life threatening; (4)-likely to be life-threatening if not treated in a timely manner, according to the FDA Guidance for Industry. ≥ Severe events included severe and potentially life-threatening events. Any ≥severe related (possibly related, probably related, and definitely related to the study treatments \[as defined by investigator\]) solicited events are reported. | ClinicalTrials.gov |
| Time frame | Day 0 (post-vaccination) to Day 7 | ClinicalTrials.gov |
| Population | SAS. Participants that were non-compliant to protocol/GCP, as per investigator, were excluded from analysis. | ClinicalTrials.gov |
