mRNA is the body’s messenger molecule that instructs cells which proteins to produce. Proteins are central to all life and are functionally required for most biological processes in the body. For the mRNA Universal Coronavirus Vaccine (mRNA UCV) product, when a person is injected with the mRNA UCV molecules, the genetic code of specific harmless “spike” protein segments, and other “conserved” targets of the virus, are delivered into the cell. The mRNA UCV molecules then instructs the body’s cells to make copies of the specific viral proteins. The immune system is now well understood to recognize these proteins as a foreign virus and build up immunity, as is the current case for successful mRNA vaccines for COVID-19. If the person later gets exposed to variants of the SARS-VoV-2 virus, the immune system will be far better prepared to respond to the viral infection. However, mRNA molecules alone are fragile and would be quickly broken down by the body’s defenses. For delivery of mRNA molecules into the cell, the commonly understood solution is to encapsulate mRNA in Lipid Nanoparticles (LNPs) that protect the mRNA from degradation. This is how the mRNA molecules of the current COVID-19 mRNA vaccines reach the cells, undamaged, whereby the mRNA molecule is expressed into the specified proteins to enable the immune response against SAR-CoV-2 viruses.
