Detailed Description

This study is an open-label, single-center, randomized phase IV clinical trial of the SARS-CoV-2 inactivated vaccine (Vero cell) manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the safety and immunogenicity of concomitant administration of the SARS-CoV-2 Inactivated Vaccine (Vero cell) with Quadrivalent Influenza Vaccine in adults aged from 18 to 59 Years. 480 healthy adults as participants are randomly assigned into two groups in the ratio 1:1. The first group was the combined immunization group, which is randomly divided into two subgroups, 120 subjects in each group. The combined immunization subgroup Ⅰ receive SARS-CoV-2 inactivated vaccine &Quadrivalent Influenza Vaccine on day 0 and SARS-CoV-2 inactivated vaccine (second dose) on day 28.The combined immunization subgroup Ⅱ receive SARS-CoV-2 inactivated vaccine on day 0 and SARS-CoV-2 inactivated vaccine (second dose) & Quadrivalent Influenza Vaccine on day 28. The second group was the non combined immunization group，which receive SARS-CoV-2 inactivated vaccine (first dose) on day 0, Quadrivalent Influenza Vaccine on day 14 and SARS-CoV-2 inactivated vaccine (second dose) on day 28.
