Brief Summary:

Phase III clinical trial was carried out in Jintan city, Jiangsu Province, China in May, 2006. Trial results showed that the vaccine had proved safety and immunogenicity. Influenza vaccine of Hualanbio has obtained production permission and marketing authorization in May, 2008.

In order to further investigate the safety and immunogenicity of the vaccine in the market, The clinical observation was planned to be conducted in Mianyang city (Yanting County), Sichuan Province, China.


Condition or disease Intervention/treatment Phase
Human Influenza Biological: Inactivated Influenza Vaccine Biological: Inactivated Influenza Vaccine of Pasteur Biological: Inactivated Influenza Vaccine of GSK Not Applicable

Detailed Description:

Dosage and administration route in this clinical trial:

Subjects age 3 years or older was vaccinated following a single 0.5ml dose immunization regime.

The preferred site of injection was the at the skin near outboard deltoid muscle of the upper arm.

The administration route is after the sanitization with 75% alcohol, intramuscularly inject the test vaccine or the control vaccines when the skin was slightly dried for those subjects complied with the inclusion requirements.

Safety indicators:

  • Post-vaccination local and systemic adverse reaction levels, together with the soliciting adverse reaction within 30 minutes ;
  • Post-vaccination local and systemic adverse reaction levels, together with the soliciting adverse reactions through 6 hours to the 29th day ;
  • Summarize the adverse events/severe adverse events and the incidence levels from the inclusion of the subjects to the completion of the clinical trial.

Immunogenicity indicators:

Evaluate the Post-vaccination immunogenicity of the test and the control influenza vaccines in persons age 3 years and older by its HI antibody level on Day 28.

Take 1:10 serum dilution as the minimum dilutability. The seroconversion in this trial was defined as the post-vaccination HI antibody titer ≥ 1:40 when the HI antibody < 1:10 before the vaccination or the post-vaccination HI antibody titer quadruply increased when HI antibody ≥ 1:10 before the vaccination.

The Immunogenicity criteria set for this clinical trial is the seroconversion shall be > 40% after 14 days of the vaccination.
