Brief Summary:
This is a randomized, blinded, positive-controlled study to evaluate the safety and immnunogenicity of Recombinant SARS-CoV-2 Vaccine (CHO Cell) LYB001, in population aged 18 years old and above. 100 subjects will be recruited in this study, including 50 aged 18-59 years old and 50 aged 60 years old and above.

Condition or disease Intervention/treatment Phase
COVID-19 Biological: low-dose LYB001 Biological: Recombinant COVID-19 Vaccine (CHO Cell) Biological: high-dose LYB001 Phase 1

Detailed Description:
All subjects will be received 3 doses of LYB001, according to the immunization schedule of 0, 28, 56 days. The adverse events within 28 days after vaccination will be observed. In addition, blood samples will be collected on day 0 before vaccination,day 14 after dose 2, and on day 14, 28 and month 3, 6, 9, 12 after full vaccination. Serum antibody levels, cellular immune responses will be analyzed to evaluate the immunogenicity and immune persistence of the vaccine.
