Can the spike protein created by the Covid mRNA vaccines be created independently of the human body, and is there a higher cost to that?
It is quite costly and difficult to manufacture and store proteins. It's very likely more efficient to have the human cells create as much protein as they can, from a relatively small amount of mRNA. Remember than one mRNA molecule can be translated into protein many many many times, so the manufacturers need to only make one mRNA molecule to get many protein molecules, whereas it would be more expensive to manufacture many protein molecules.
It's kind of a &quot;give a man a fish, he eats for a day, teach a man to fish, he eats forever&quot; situation. Better to give the body the instructions (mRNA) than the product, for cost effectiveness.
