That is all true as long as the RNA doesn’t replicate itself and only produces antigens. However, I couldn’t find any papers at all that discussed if any of the current mRNA vaccine candidates self replicate their RNA to amplify the antigen production. I’d love some good references that address that.
- lbeltrame 6y agoThis doesn't replicate, AFAICS. The one in Phase I by Imperial College is instead self-replicating.
- antgiant 6y agoDid some more searching today and this one does in fact amplify just like the Imperial College one
- lbeltrame 6y agoDid it? Can you point me to the relevant paper? It's been a while since I read their phase 1 data.

- lbeltrame 6y ago> Pfizer Inc. (New York, NY) in partnership with BioNtech (Germany) has also developed a saRNA prototype vaccine, although the details of this vector/formulation have not been disclosed yet. AFAICS, this is not BNT162b2, which is the one that we are talking about. There are 3 other candidates, one of them is the self-amplifying one.
- antgiant 6y agoLooks like you are right! Thanks for the good news!
- The_rationalist 6y agoSo will this be in significant quantity in my body for years?
- antgiant 6y agoI don’t know. Busy straining my biology knowledge trying to figure that out. The paper seems to imply maybe not? https://www.sciencedirect.com/science/article/pii/S1879625720300705 https://www.sciencedirect.com/science/article/pii/S187962572...
