Participant Flow

Up to 100 subjects between the ages of 18 and 59 were planned with 83 subjects enrolled and 82 subjects vaccinated. Pre- and post-vaccination serum samples were collected from 78 subjects and were analyzed in the Efficacy population.

A total of 83 subjects were recruited and 78 (39 Stratis® and 39 NS) completed the study. One Stratis® group subject (subject # 23) discontinued from the study prior to vaccination.

PRIMARY outcome

Timeframe: 28 days

Population: Seroconversion against the hemagglutinin antigens contained in the vaccine were assessed in the Immunogenicity Population.

Seroconversion is defined as a 4-fold rise in HAI titer in post-immunization serum relative to pre-immunization serum, or if pre-immunization serum had an undetectable titer (\<1:10), attainment of a post-immunization titer of ≥1:40.

SECONDARY outcome

Timeframe: 4 days

Population: Data included in the analysis were collected on a 4-Day Diary Card from the safety population and grade \>1.

Vaccine reactogenicity will be collected on a patient-completed diary card daily for seven days post-vaccination. The following adverse events will be solicited on the diary card: injection site tenderness, injection site pain, injection site redness, injection site swelling, injection site itching, injection site bruising, fatigue, muscle aches, headache, decreased appetite, fever, pruritus.
