Description
To evaluate the inter-batch consistency (CI) of quadrivalent influenza vaccine (split virion) among healthy people aged 18-59 years; Secondly, to evaluate the safety and immunogenicity of quadrivalent influenza vaccine (split virion) in the expanded population aged 3 years and above, in order to observe the rare adverse reaction of 1‰.

Status
Completed
Treatment
One dose of quadrivalent influenza virus split vaccine was administered
Safety observation: All 4900 vaccine recipients participated in the safety observation after vaccination, and were followed up for adverse events (AE) within 30 minutes and 0-30 days after vaccination, and SAEs within 6 months after vaccination. In addition to 1050 recipients aged 18-59 years who were included in the first layer test, 350 recipients aged 3-17 years and 350 recipients aged ≥60 years were randomly selected from each group. Blood samples were collected before and 30 days after vaccination for influenza virus HI antibody detection.
Arms:
Approval consistency study, Safety and immunogenicity in a larger vaccination cohort aged 3 years and older
Size
4900
Primary endpoint
To evaluate the safety and immunogenicity of Hualan Biovar quadrivalent influenza vaccine in a larger population in the real world, and to observe rare adverse drug reaction (ADR) of 1‰.
The safety was observed until 6 months after the full course of immunization
