Why not just inject the double-stranded cDNA that codes for the spike protein of the virus? What additional step or steps would you need to use to get the human muscle cells to produce the spike protein if the cDNA was injected to serve as the virus

  • Why not just inject the double-stranded cDNA that codes for the spike protein of the virus? What additional step or steps would you need to use to get the human muscle cells to produce the spike protein if the cDNA was injected to serve as the virus?
  • The new Covid19 vaccine produced by two companies (Pfizer, Moderna) uses mRNA coding for part of the spike protein of the virus. The virus uses the spike protein to invade human cells where it replicates. Is it surprising that the mRNA must be stabilized with chemicals that need ultra-cold or frozen storage to protect the mRNA from degradation before it causes human muscle cells to make the spike protein?
