Phase I Trial of a Recombinant COVID-19 Vaccine (CHO Cell)

Summary

This is a phase I, randomized, placebo-controlled, double-blind study, to evaluate safety and immunogenicity of a recombinant SARS-CoV-2 vaccine (CHO cell) in Chinese healthy population aged 18 years and older. After randomization, the trial for each subject will last for approximately 13 months. Screening period is 1 week prior to randomization (Day -7 to Day -1), and each dose of either SARS-CoV-2 vaccine (CHO Cell) or placebo will be given intramuscularly (IM) on Day 0 and Day 14 for a two-dose regimen, or on Day 0, Day 14, and Day 28 for a three-dose regimen. Subjects who are ≥18 years old and ≤ 59 years old will be enrolled in adult group, and healthy elderly population who are \>59 years old will be enrolled in elderly group.
