Official title
Randomized, Age-stratified, Double Blind, Controlled Phase 3 Study Comparing a Vero Cell-derived Trivalent Seasonal Influenza Vaccine Made by the Modified Manufacturing Process With Vaccine Made by the Current Manufacturing Process and a Licensed Trivalent Influenza Vaccine in Healthy Adults Aged 18 Years and Older
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine if a Vero cell-derived trivalent seasonal influenza vaccine produced by the modified manufacturing process: 1. induces immune responses comparable to that produced by the current manufacturing process 2. has an acceptable safety profile compared to a licensed trivalent seasonal influenza vaccine 3. demonstrates consistency of immune response among three different lots.
