R520A is an mRNA COVID-19 vaccine specifically targeting the Omicron variant developed by Wuhan Recogen Biotechnology Co., Ltd., a subsidiary of the Company. R520A adopts a self-developed lyophilization technology that can effectively sustain the physiochemical properties and bioactivity of mRNA-LNP and achieve long-term storage at 2℃–8℃. In the pre-clinical studies, the level of neutralizing antibody titers against Omicron variant increased to a high level of 4,758 and it can also induce neutralization response against Delta variant, indicating its promising immunogenicity profile.

The relevant research results have been posted on the preprint server, bioRxiv.
