Immunogenicity and Safety of the Shenzhen Trivalent Inactivated Influenza Vaccine Versus a Trivalent Influenza Vaccine Comparator in Healthy Chinese Subjects Aged 18 to 59 Years

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Summary of Geometric Mean Titers (GMTs) of Each of the Three Strains of TIV Antibodies Following a Single Dose of SP Shz TIV or Hualan TIV
Time Frame: Day 28 post-vaccination
GMTs were assessed using the hemagglutination inhibition (HAI) assay.
Day 28 post-vaccination
Percentage of Participants with TIV Seroconversion Following a Single Dose of SP Shz TIV or Hualan TIV
Time Frame: Day 28 post-vaccination
Seroconversion rates were assessed using a HAI assay. Seroconversion was defined as titers <10 (1/dil) at Day 0 and post-injection titer ≥40 (1/dil) at Day 28, or titer ≥10 (1/dil) at Day 0 and a ≥4-fold increase in titer (1/dil) at Day 28.
Day 28 post-vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
