ZF2001 Booster Immunization Clinical Trials of 6 Months After the Completion of Basic Immunization

Summary

The purpose of this study is to evaluate the immunogenicity and safety of the recombinant novel coronavirus vaccine (CHO cells) after the booster immunization. It is planned to screen 300 subjects of 18 years old and above who have completed the basic immunization of recombinant novel coronavirus vaccine (CHO cells), to evaluate the immunogenicity and safety of the booster immunization of 6 months (window period ± 1 month) after the basic immunization. Investigate the geometric mean titer (GMT), GMI and 4 times growth rate of SARS-CoV-2 neutralizing antibody and RBD protein binding antibody 14 days, 30 days, and 6 months after booster vaccination; the incidence of all AEs within 1 month after the booster vaccination, the incidence of all serious adverse events (SAE) within 6 months after the booster vaccination.
