Prevention of Influenza Clinical Trial

Status Completed

Clinical Trial Summary

This study is aimed to confirm the lot-to-lot consistency of 3 consecutive batches of 'GC FLU® Pre-filled Syringe Injection' and 'GC FLU® Injection' in the lot-to-lot

Clinical Trial Description

This is a Post-Marketing, Multicentre, Open, Randomized Phase 4 Clinical Study. Subjects who gave voluntary written informed consent to participate in the study were screened for eligibility in the study, and those who met the eligibility criteria were randomized in the investigational group.

An investigator assessed the effectiveness (immunogenicity) and safety of the study vaccine in each subject during his/her participation in the study.

Subjects were randomized (Visit 1) into the investigational group according to a randomization table previously generated, and were vaccinated with influenza split vaccine, 'GC FLU®Pre-filled Syringe Injection' and 'GC FLU®Injection'.

12 Assessments for HI titre to each strain of influenza were performed at Visit 1 (pre-vaccination), and at Visit 3 (21 days after vaccination) for the efficacy (immunogenicity) evaluation [Picture 1].For the safety assessment, subject diaries were handed out to subjects, who were instructed to record any adverse event emerging ager the receipt of study vaccine. ;
