By contrast, by using just the genetic material that makes the Spike glycoprotein—the protein on the surface of the coronavirus that is essential for infecting human cells—the design and manufacture of the vaccine is simplified. The genetic material mRNA is easy to make in a laboratory. Manufacturing an mRNA vaccine rather than a protein vaccine can save months if not years. Another factor that accelerated vaccine development was the swift and efficient recruitment of patients for clinical trials. True or false: The argument has logical strength because the premises of this argument support the conclusion.
