The Evolution of Vaccines

When you have a live virus, when you're infected by a virus or you're giving a live vaccine, those viruses infect your cell and then your cell processes them. And as the virus tries to replicate any virus that infects you, I want to say hijacks your cellular machinery but certainly uses different nucleotides and things that you have in your cells to help itself reproduce. So if we were to take that spike protein and not give it as part of an mRNA vaccine, but give it as just what we call a subunit protein vaccine, which is old school technology,. It's really kind of wild to think about it.
