Phase II Clinical Trial of COVID-19 mRNA Vaccine in Adults Aged 18 Years and Older

COVID-19 Clinical Trial

Official title:
A Randomized, Double-blind, Dose-exploring, Placebo-controlled, Multi-center Phase II Clinical Trial Evaluating the Safety and Immunogenicity of COVID-19 mRNA Vaccine in Adults Aged 18 Years and Older

Clinical Trial Summary

To evaluate the safety and immunogenicity of COVID-19 mRNA vaccine in people aged 18 years and older, 300 participants will be enrolled and divided into two groups: low- and high-dose groups. Each dose group (150 people) will be divided into 2 age groups (75 each):18 to 59 years old and ≥ 60 years old. The subjects will be randomized into vaccine group or placebo group in a ratio of 2:1. Subjects will complete 2 doses of vaccination on Day 0 and Day 21, in which the low-dose group will received 0.3 ml of the study vaccine or placebo, and the high dose group received 0.5 ml of the study vaccine or placebo.
