Inactivated Split Virus Seasonal Influenza Vaccine (Vero Cell-Derived)

Completed · Phase 3

Conditions studied: Influenza

In brief

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.
