About

This was a blind-observer, monocenter, randomized, comparative, Phase IV study designed to evaluate the immunogenicity and safety of the Sanofi Pasteur Shenzhen Trivalent Influenza Vaccine (SP Shz TIV) versus the Trivalent Influenza Vaccine manufactured by Hualan Biological Engineering Inc (Hualan TIV) comparator in healthy Chinese participants aged 18 to 59 years.

Full description

This study is designed to demonstrate the non-inferiority of the immune response in terms of geometric mean titers (GMTs) and seroconversion rates for the 3 strains (A/H1N1, A-H3N2, and B) after a single dose of either the SP Shz TIV or Hualan TIV. Vaccine immune responses will be assessed on Day 0 (pre-vaccination) and Day 28 post-vaccination. Solicited reactions will be collected from Day 0 up to Day 7 after vaccination, unsolicited non-serious adverse events (AEs) will be collected from Day 0 up to Day 28 post-vaccination, and serious AEs will be collected from Day 0 up to 6 months post-vaccination.

To be considered of non- childbearing potential, a female must be post-menopausal for at least 1 year or surgically sterile
Participation at the time of study enrollment (or in the 4 weeks preceding the trial vaccination) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure
Receipt of any vaccine or planned receipt of any vaccine within the period from 2 weeks before trial vaccination to 2 weeks following trial vaccination
Previous vaccination against influenza (in the previous 6 months) with either the trial vaccines or another vaccine
Receipt of immune globulins, blood or blood-derived product in the past 3 months
Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
Known systemic hypersensitivity to any of the vaccines components, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances
Self-reported thrombocytopenia contraindicating intramuscular vaccination
Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination
Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
Current alcohol abuse or drug addiction
Chronic illness that, in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion
Moderate or severe acute illness/infection (according to Investigator judgment) on the day of vaccination or febrile illness (axillary temperature ≥ 37.1°C). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided
Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw
Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study
