Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical trial aimed to gather safety and immunogenicity data in COVID-19 vaccine-experienced healthy adults. The main questions it aims to answer are:

* The neutralizing antibodies levels of bivalent mRNA vaccines RQ3027(Alpha/Beta+Omicron XBB.1.5) and RQ3025(Alpha/Beta+Omicron BA.2/4/5) and monovalent mRNA vaccine RQ3013 against the current SARS-CoV-2 circulating variant.
* The safety profile of RQ3027 and RQ3025 given as a second booster dose to COVID-19 vaccine-experienced participants 18 through 55 years of age.
* Explore the protective efficacy by documenting confirmed COVID-19 cases after vaccination.
