A solution has been discovered that provides a more effective Coronavirus vaccine. The solution is an mRNA vaccine encoding a SARS-CoV-2 nucleoprotein (N) (mRNA-N) in combination with an mRNA vaccine encoding SARS-CoV-2 spike protein(S) (mRNA-S). Chemically modified mRNA-N (pseudouridine) and/or chemically modified mRNA-S (pseudouridine) can be synthesized and packaged in lipid nanoparticles (LNP). In mouse and hamster models, it was shown that mRNA-N alone is immunogenic and can significantly diminish viral loads in the mouse lung after prime-boost intramuscular immunization. In addition, the combinatorial mRNA-N/mRNA-S vaccination induces substantially stronger protection against SARS-CoV-2 than vaccination with mRNA-S alone.

After DNA vaccine construction, HEK293T cells were transfected and analyzed for protein expression capacity by IFA, Western blot and RT-qPCR, then BALB/c mice and K18-hACE2 transgenic mice were immunized with DNA vaccine administered intramuscularly (IM) and intradermally (ID) using an electroporator device three times on days 0, 14 and 56. Humoral and cellular immune responses were then analyzed using recombinant ELISA, Western blot, surrogate virus neutralization assay, microneutralization assay, Cytokine ELISA and flow cytometry.
