PRIMARY outcome

Timeframe: within 4 hours following vaccination

Population: Immediate complaints were vaccination symptoms that were solicited and observed at 30 minutes (+15 minutes) and (±30 minutes) after the vaccination on Day 0.

SECONDARY outcome

Timeframe: 28 days after vaccination

Population: The immunogenicity of the vaccine was evaluated by measuring the number of subjects who demonstrate seroconversion either by developing a measurable titer following vaccination or by showing a significant increase in HAI serum antibody titers post-vaccination.
