The present study aims to evaluate the safety and immunogenicity of the new influenza subunit vaccine produced in Madin Darby Canine Kidney (MDCK) cells in healthy adult and elderly subjects.

Clinical Details

Official title: A Phase III, Observer-Blind, Randomized, Multi-Center Study to Evaluate Safety, Tolerability and Immunogenicity of a Single Intramuscular Dose of a Trivalent Subunit Influenza Vaccine Produced in Mammalian Cell Culture and of a Trivalent Subunit Influenza Vaccine Produced in Embryonated Hen Eggs, in Healthy Adult and Elderly Subjects

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Prevention

Primary outcome:

Percentages Of Subjects Who Achieved HI Titer ≥40 After One Vaccination of Cell Culture-derived (cTIV) or Egg-derived (TIV) Influenza Subunit Vaccines

Percentages Of Subjects Who Achieved Seroconversion Or Significant Increase In HI Titer After One Vaccination of cTIV or TIV

Geometric Mean Ratio of Subjects After One Vaccination of cTIV or TIV

Secondary outcome: Number of Subjects Who Reported Solicited Local and Systemic Reactions up to 7 Days After Vaccination


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
