Population: The analysis was performed on the According-To-Protocol cohort for immunogenicity, which included all evaluable subjects who received one dose of either study vaccine, for whom administration site of study vaccine was known, who did not receive a vaccine forbidden in the protocol and for whom immunogenicity data were available.

A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer \<1:10 and a post-vaccination titer ≥1:40 or a pre-vaccination titer ≥1:10 and at least a four-fold increase in post-vaccination titer. The 3 influenza strains assessed were A/New Caledonia, A/Wisconsin and B/Malaysia.

SECONDARY outcome

Timeframe: During the 7-day (Days 0-6) post-vaccination period

Population: The analysis was performed on the Total Vaccinated cohort, on all subjects with the documented dose.

Assessed solicited local symptoms were ecchymosis, pain, redness and swelling at injection site. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling/ecchymosis = redness/swelling/ecchymosis spreading beyond 50 millimeters (mm) of the injection site. All solicited local symptoms were considered to be related to vaccination.

Timeframe: During the 30-day (Days 0-29) post vaccination period

Population: The analysis was performed on the Total Vaccinated cohort, on all subjects with the documented dose.

Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any = any unsolicited AE regardless of intensity or relationship to vaccination. Grade 3 = unsolicited AE that prevented everyday activities. Related = unsolicited AE assessed by the investigator as related to the vaccination.
