Does anyone know how they manage to produce complex microstructures like that, RNA inside a lipid capsule, on such a large scale?
Does these vaccines need an adjuvant to work, or is the change to the affected cells large enough to trigger an immune reaction?
- m-ee 6y agoThere’s no additional adjuvant. I have no idea how they’re produced, would love to learn more.
- blackbear_ 6y agoThis article [1] has a section with several references on that, with the most used technique [2] being depicted in fig. 3 (this is from 2016 so there might be a more recent technique around now). The basic principle is to mix a solution with lipids and one with the mRNA and pump it through a channel with herringbone-shaped incisions that generate turbulence in the fluid. Apparently, the turbulence makes lipids surround the mRNA and stick together to form the nano-particle.

I wonder what the rate of lipid-surrounded mRNA is after the process. Say you fire 100 mRNAs through this construct, will 90 of them be surrounded by lipids afterwards? Or 30? Or 100?
