Safety and Immunogenicity of MF59C.1 Adjuvanted Trivalent Subunit Influenza Vaccine in Elderly Subjects

Phase 3
Completed
Conditions
Influenza
Interventions
Biological: MF59 adjuvanted trivalent subunit influenza vaccine (aTIV)
Biological: Non-adjuvanted trivalent subunit influenza vaccine (TIV)
Registration Number
NCT01162122
Lead Sponsor
Novartis Vaccines
Brief Summary

The present phase III study aims to evaluate the safety and immunogenicity of MF59-adjuvanted subunit seasonal influenza vaccine and to evaluate the consistency in the manufacturing process of three consecutive lots of MF59-adjuvanted subunit seasonal influenza vaccine with respect to immunogenicity in subjects aged 65 years and older. The active comparator non-adjuvanted seasonal influenza vaccine is approved for use in this age group in the United States and will be used to provide a comparative assessment for immunogenicity and safety.
