In vaccines which use mRNA to produce immunity, mRNA from the virus is injected into the arm of a patient. The mRNA usually represents a gene from the virus which produces the spike proteins on the outside of the virus. After the vaccinated person's cells create spike proteins similar to the virus' spike proteins, the immune system will recognize the invading virus. The process by which the cells' mRNA creates the spike proteins is: a. translation b. transcription c. replication​
