Mrna and adenovirus vector vaccines shift the factory production of viral proteins into the body.

“What Moderna and what Pfizer, and what AstraZeneca are doing is they're moving that factory production points out of their realm and they're putting it into your body. So it's your body that's now making the protein, it's your body that's doing this, they don't have to do that. And therefore they can get a product faster.”
