Amazing read. Leaves me with wondering how do we make sure the sequences injected with the vaccine are exactly the same sequences that are described. Do they have some kind of verification method that there was no encoding errors and they won't inject some random sequences? Also what's the risk of this erroneous sequences to be harmful? The futurologist in me imagines prescriptions containing RNA sequences which you get to the nearest pharmacy to 3D print the drug. Future of the medicine looks more exciting than ever.
