NCT05499351

Brief Summary

This study is a single center , randomized ,controlled and open-label phase Ⅳclinical trial of the booster immunization with the third dose of inactivated COVID-19 vaccine(CoronaVac)manufactured by Sinovac Research \& Development Co.,Ltd. The purpose of this study is to evaluate the immunogenicity and safety of the third dose of COVID-19 vaccine,inactivated (Vero Cell) co-administration with influenza vaccine and pneumococcal polysaccharide vaccine in healthy population aged 18 years and older.
