Brief summary

phase I study will evaluate the safety and tolerability of GEN2-Recombinant COVID-19 Vaccine (CHO cells) in healthy people aged 18 years and older. A total of 234 subjects were enrolled, of which 126 were enrolled in the 18-59-year-old group, and were randomly assigned to receive experimental vaccine 1, experimental vaccine 2, experimental vaccine 3 and placebo in a ratio of 2:2:2:1; 60- A total of 54 people were enrolled in the 69-year-old and ≥70-year-old groups, and were randomly assigned to receive the experimental vaccine 1 and placebo according to the ratio of 2:1.
