The coronavirus RNA vaccine is correctly produced with recombinant technology following the steps as follows:
1. Identify and clone the coronavirus spike protein gene into a plasmid.
2. Use the plasmid containing the coronavirus spike protein to produce spike protein mRNA.
3. Inject spike protein mRNA into recipients.
4. Recipient cells use the spike protein mRNA to produce and display spike protein on the cell surface.
5. The spike protein stimulates an immune response that ideally will protect the recipient from future coronavirus infections.
