Safety and Immunogenicity Study of Quadrivalent Influenza Virus Vaccine in Healthy People Aged Years 3-60

Study Overview
=================
Brief Summary
-----------------
This study evaluates the safety and immunogenicity of the quadrivalent influenza virus vaccine in healthy people aged years 3-60.Subjects will be randomly divided into 3 groups,receiving the test vaccine, commercially available trivalent influenza vaccine and trivalent influenza vaccine containing new influenza B component respectively. Each group has 800 subjects,2400 in total.

Conditions

Intervention / Treatment
-----------------
* Biological: one dose test vaccine
* Biological: one dose commercially available trivalent influenza vaccine
* Biological: One dose of Quadrivalent Influenza Virus Vaccine
