Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The clinical trial was designed to evaluate the immunogenicity and safety against pediatric Inactivated influenza vaccine (Split Virion) (0.25ml formulation) of Hualan administered on infants age 6 months to 36 months.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The clinical trial was designed randomized and double-blind. Participants included up to 810 persons (540 persons in test group and 270 persons in control group).

Healthy 6-36 months infants were selected, whose guardians were volunteers and had signed the informed consent. Subjects were selected according to the inclusion and exclusion criteria. Every subject accepted 30min's observation in the hospital after vaccination and received periodic follow-up till the fourth week after the boost vaccination.

Blood of subjects was collected at the third week after the boost vaccination for the analysis of the immunogenicity. During the test, the adverse reactions and detailed information were reported to the SFDA under the status of blinding every month. Unblinding was conducted after the completion of the follow-up of subjects.
