[Clinical Trials]
In a randomized, blinded, positive-controlled Phase III pivotal registration clinical trial completed in China, a total of 3,000 subjects aged 3 and above were enrolled, in which 800 subjects aged ≥65 years, and 700 subjects aged 18-64 years, 700 subjects aged 9-17 years, and 800 subjects aged 3-8 years. The subjects in each age group were randomly vaccinated with 1 dose of this product or the quadrivalent influenza virus split vaccine at a ratio of 1:1. Blood samples were collected before immunization and at 28 days after immunization, and the HI antibody titer against influenza virus in the serum of subjects was detected by the micro-hemagglutination inhibition test method.
The HI antibody GMTs against influenza virus in the whole study population in the trial group after immunization were: 400.39 for H1N1, 436.71 for H3N2, 267.60 for BY, and 77.80 for BV (see Table 1 for details); the antibody seroconversion rates after immunization were: 82.71% for H1N1, 91.22% for H3N2, 88.36% for BY, 84.96% for BV (see Table 2 for details); and the antibody protection rates (≥1:40) after immunization were: 96.60% for H1N1, 97.96% for H3N2, 95.92% for BY, 89.45% for BV (see Table 2 for details). FAS results were consistent with PPS results.

Seroconversion: With 1:10 serum as the lowest dilution, those with HI antibody <1:10 before immunization and HI antibody titer ≥1:40 after immunization were considered to achieve seroconversion, or those with HI antibody ≥1:10 before immunization and 4-fold increase in HI antibody titer after immunization were considered to achieve seroconversion.
Seroconversion rate: the ratio of subjects who achieved HI antibody seroconversion after immunization; protection rate: the ratio of subjects who had HI antibody titer ≥ 1:40 after immunization.
The non-inferiority test was valid if the lower limit of the 95% CI of the antibody seroconversion rate difference (trial group - control group) was >-10%.
